ABSTRACT The increased spread of Echinococcus multilocularis into novel areas has created a need for early detection and monitoring of parasites within wild canid populations. In order to survey the prevalence and relative intensity of helminthes in wild canid populations, coyote, red fox and gray fox scat samples were collected during February and March 2012 at Letterkenny Army Depot, in south central Pennsylvania, USA. Using standard fecal flotation, 13 different parasites were identified in 75 fecal samples, of which 40% of coyote (n=35) and 72.5% (n=40) of fox samples contained evidence of at least one parasite. This represents 8 new species now known to parasitize coyotes and foxes in Letterkenny Army Depot when compared with previous published research. Eleven of the 13 parasites identified were shared between coyotes and foxes. Fox samples had a higher prevalence of parasitism than did coyote samples; however, the relative intensity of parasitism was greater in coyote samples. While parasitism with Taenia sp., Capillaria sp., Isospora sp., Toxocara canis, Toxascaris leonina, Strongyloides stercoralis and Uncinaria stenocephala is likely detrimental, we did not identify Echinococcus sp. or other zoonotic parasites. We recommend continued surveillance for parasites found within wild canids through standard fecal flotation techniques as well as molecular and specific DNA analyses.

To verify the presence of cross-reaction among leishmaniosis, ehrlichiosis and babesiosis in serological diagnostics used in human visceral leishmaniasis control programs, serum samples from leishmaniasis endemic and non-endemic areas were collected and tested by Indirect Fluorescent Antibody (IFAT) and Enzyme-linked immunosorbent assay (ELISA). All serum samples from endemic areas were positive for Leishmania sp., by ELISA and IFAT, 51% positive for Babesia canis and 43% for Ehrlichia canis by IFAT. None of the serum samples from non-endemic areas were positive for Leishmania sp., by IFAT, but 67% were positive for B. canis and 78% for E. canis using the same test. When tested by ELISA for Leishmania sp., four samples from non-endemic area were positive. These dogs were then located and no clinical signs, parasites or antibody was detected in new tests for a six month period. Only one of these 4 samples was positive for B. canis by IFAT and ELISA and three for E. canis by IFAT. The results of the work suggest a co-infection in the endemic area and no serological cross-reaction among these parasites by IFAT and ELISA.

AbstractThe aim of this study was to investigate the morphology of Demodex canis and Demodex sp. cornei found in six dogs with canine demodicosis. A deep skin scraping technique was used for Demodex mite detection. Measurement data of 52 adult D. canis mites (26 females, 25 males and one specimen whose sex could not be determined) and 39 adult Demodex sp. cornei mites (22 females, 14 males and three specimens whose sex could not be determined) were reported. The correlation between body size of both Demodex species were estimated by the Student’s t-test. There was a significant correlation between short-tail and long-tail forms and total body length and length of the podosoma and opisthosoma (p<0.05). A significant difference was not found between the length of the gnathosoma and short-tail and long-tail forms (p>0.05). Demodex sp. cornei and D. canis, found in dogs from Vladivostok, were smaller than species from other countries. However, the present data did not significantly differ from other studies with D. canis and Demodex sp. cornei descriptions.

Haemoparasites of the genus Babesia infect a wide range of domestic and wild animals. Feline babesiosis is considered endemic in South Africa, while data on Babesia spp. infection in felids in Europe is scarce. Using samples from 51 wild felids, 44 Felis silvestris and 7 Lynx lynx, the study aimed to determine the presence and genetic diversity of Babesia spp. in wild felids in Romania by analyzing the 18S rDNA and two mitochondrial markers, cytochrome b (Cytb) and cytochrome c oxidase subunit I (COI) genes. By 18S rDNA analyses, Babesia spp. DNA was detected in 20 European wild felids. All sequences showed 100% similarity to B. canis by BLAST analysis. Conversely, Cytb and COI analyses revealed the presence of two Babesia spp., B. pisicii n. sp., which we herein describe, and B. canis. The pairwise comparison of both mitochondrial genes of B. pisicii n. sp. showed a genetic distance of at least 10.3% from the most closely related species, B. rossi. Phylogenetic analyses of Cytb and COI genes revealed that B. pisicii n. sp. is related to the so-called “large” canid-associated Babesia species forming a separate subclade in a sister position to B. rossi.

O aumento da incidência das infecções fúngicas, bem como o registro crescente de resistência e falha terapêutica, têm impulsionado a realização de estudos de prospecção de fitoquímicos com propriedades antifúngicas. Diante do exposto, o presente estudo investigou o potencial antifúngico de extratos de Baccharis ligustrina, B. schultzii, Croton jacobinensis, Licania rigida, Moringa oleifera, Vernonia sp. e V. brasiliana, e de óleos essenciais de Lippia alba (Quimiotipos 1, 2, 3 e 4) e Ocimum gratissimum. Inicialmente, foi realizada uma avaliação qualitativa da atividade antifúngica de cada amostra por meio do método de difusão em ágar, frente a cepas de Candida albicans e Microsporum canis, mostrando que apenas os extratos de M. oleifera (MLF-C) e Vernonia sp. (TVS-H) apresentaram atividade frente a C. albicans e M. canis, com halos de inibição =10mm. Também foram determinadas a concentração inibitória mínima (CIM), frente a 12 cepas de C. albicans e M. canis, e a toxicidade aguda de MLF-C e TVS-H, através de protocolos do Clinical and Laboratory Standards Institute (CLSI) e ensaio com Artemia sp., respectivamente. A CIM (80%) de MLF-C e TVS-H variou de 0,156 a 2,5mg mL-1 frente C. albicans e de 0,039 a 1,25 e 0,039 a 0,625mg mL-1 para M. canis, respectivamente. A CIM (100%) de MLF-C e TVS-H variou de 0,625 a 2,5mg mL-1 frente C. albicans é de 0,039 a 2,5 e 0,078 a 1,25mg mL-1 para M. canis, respectivamente. As doses letais (DL50) para o MLF-C e TVS-H foram de 201,09 e 204,17mg mL-1, respectivamente, sendo, portanto, demonstrada a baixa toxicidade desses extratos. Os extratos de M. oileifera e Vernonia sp. apresentaram atividade antifúngica frente cepas de C. albicans e M. canis, abrindo a perspectiva de estudos para caracterização dos seus componentes bioativos.

The purpose of the research is identifying a species of the causative agent of canine babesiosis in the Kirov Region.Materials and methods. To determine the parasite species, we microscopically examined smears from the peripheral blood of sick dogs stained by the Romanowsky-Giemsa method and Leucodif. The microscopy was performed with a binocular microscope Micromed-1. For morphometric assessment of the causative agent, we used a digital camera and software for image analysis ToupView.Results and discussion. We found parasites of various shapes and sizes in erythrocytes of the dogs’ blood in an amount from 1 to 4, rarely 8, 16, and 32. Parasites having large paired pear-shaped forms prevailed (100% in Kirov and 92.86% in Vyatskiye Polyany), which were mainly connected by thin ends at an acute angle and located in the center of an erythrocyte. In Vyatskiye Polyany, we found single small pear-shaped parasites in 7.14%, that were also located along the periphery of an erythrocyte. Based on morphological features, the causative agent of “large” Babesia infection (piroplasmosis) of dogs in the Kirov Region is Babesia (Piroplasma) canis (Piana et Galli Walerio, 1895), and of small Babesia infection of dogs is B. (P.) gibsoni (Patton, 1910). In the Kirov City environment, babesiosis proceeds in monoinfection (81.58% prevalence of infection), and the B. canis infection rate is 28.57% in the south of the Region. We recorded a mixed infection of B. canis + Anaplasma sp. (35.71%), B. canis + Anaplasma sp. + Ehrlichia canis (14.29%), B. canis + E. canis (14.29%), and B. gibsoni + Anaplasma sp. (7.14%) in 71.43%.

Over recent decades, diseases have been shown to be important causes of extinctions among wild species. Greater emphasis has been given to diseases transmitted by domestic animals, which have been increasing in numbers in natural areas, along with human populations. This study had the aim of investigating the presence of intestinal helminths in wild canids (maned wolf, Chrysocyon brachyurus, and crab-eating fox, Cerdocyon thous) in the Serra do Cipó National Park (43-44º W and 19-20º S) and endo and ectoparasites of domestic dogs in the Morro da Pedreira Environmental Protection Area (an area surrounding the National Park). The Serra do Cipó is located in the state of Minas Gerais, Brazil. Among the enteroparasites found in domestic and wild canids, the following taxons were identified: Ancylostomidae, Trichuridae, Toxocara sp., Spirocerca sp., Physaloptera sp., Strongyloides sp., Cestoda, Dipylidium caninum, Diphyllobothriidae, Hymenolepidae, Anoplocephalidae, Trematoda, Acanthocephala and Isospora sp. Domestic dogs were positive for leishmaniasis and Babesia canis in serological tests. Among the ectoparasites, Rhipicephalus sanguineus, Amblyomma cajennense and Ctenocephalides felis felis were observed in domestic dogs. Variations in the chaetotaxy of the meta-episternum and posterior tibia were observed in some specimens of C. felis felis.

Toxoplasmosis, leishmaniasis, and ehrlichiosis are zoonoses that have cosmopolitan distribution and cause important clinical changes in dogs and humans. Dogs are important in the epidemiology and transmission of Leishmania infantum and Ehrlichia canis and serve as indicators of environmental contamination by the transmission of Toxoplasma gondii. The aim of this study was to detect antibodies against T. gondii, Leishmania spp., and E. canis in dogs from Bahia and identify the risk factors associated with infections. Blood samples were collected from 353 dogs from several municipalities of Bahia and the sera were tested using reaction of indirect immunofluorescence (RIFI) for T. gondii and Leishmania spp. and enzyme-linked immunosorbent assay (ELISA) for E. canis. The data were tabulated and analyzed using EPI-INFO 7.1.5 program. Of 353 samples analyzed, 144 (40.8%) were positive for T. gondii (antibody titer 16-4,096) and 92 (26.1%) were seropositive for Leishmania spp. (antibody titer 40-160). The seropositivity for E. canis was the highest as compared to that of the other agents. Furthermore, 184 (52.1%) samples were positive for antibodies against E. canis. Sixteen (4.5%), 71 (20.1%), and 25 (7.1%) samples were co-infected with T. gondii and Leishmania spp., T. gondii and E. canis, and E. canis and Leishmania spp., respectively, while 20 (5.7%) dogs presented co-seropositivity for all three etiological agents. Risk factors such as age, sex, habitat (stray/not stray), and region of dog’s origin were analyzed; age ( ? 1 year) was significantly associated with T. gondii (p = 0.03) and E. canis (p = 0.02) infection and stray animals were more exposed to T. gondii (p = 0.03) and Leishmania spp. (p = 0.01) infection. The results confirmed the heterogeneous distribution of the three etiological agents in dogs from Bahia and identified animals with co-infections.

Hemoparasitic infections are frequently encountered in wild carnivores. Although, mostly, the infections are typically asymptomatic, they can be pathogenic under certain circumstances, viz. concurrent disease and stress due to captivity, habitat degradation, adverse climatic conditions or immunosuppression. The present study was undertaken to genotype Babesia sp. and Hepatozoon sp. isolated from lions of Lion Safari, Etawah, Uttar Pradesh, India and establishing phylogenetic relationship based on 18S rRNA sequence with other isolates around the globe. Blood samples of five Asiatic lions, received in the Clinical and Wildlife Parasitology Laboratory, Division of Parasitology, Indian Veterinary Research Institute, were screened microscopically for any haemoparasitic infection. Out of five, one sample was positive for Hepatozoon sp. and another sample was positive for Babesia sp. Polymerase chain reaction of 18S rRNA with genomic DNA amplified 1775 bp and 1665 bp segments for Hepatozoon sp. and Babesia sp., respectively. Sequencing of PCR amplicon and BLAST analysis indicated that Hepatozoon spp. in Asiatic lion was 99% similar to Hepatozoon felis isolate of Spain and Babesia spp. like organism was 95% similar to Babesia canis 18S ribosomal RNA gene of Israeli cat and Babesia canis canis of domestic dogs. Based on the literature available in public domain and the findings of present study, it can be concluded that these haemoprotozoa are not restricted to their respective hosts, and more than one genotype can be found in the same habitat. Cryptic babesiosis and hepatozoonosis can flare up in immuno-compromised animals and may result into fatal consequences in endangered Asiatic lion.

An analysis of 16S rRNA gene sequences from archived clinical reference specimens has identified two novel Neisseria species. For each species, two strains from independent sources were identified. Amongst species with validly published names, the closest species to the newly identified organisms were Neisseria canis, N. dentiae, N. zoodegmatis, N. animaloris and N. weaveri. DNA–DNA hybridization studies demonstrated that the newly identified isolates represent species that are distinct from these nearest neighbours. Analysis of partial 23S rRNA gene sequences for the newly identified strains and their nearest neighbours provided additional support for the species designation. Bayesian analysis of 16S rRNA gene sequences suggested that the newly identified isolates belong to distinct but related species of the genus Neisseria, and are members of a clade that includes N. dentiae, N. bacilliformis and N. canis. The predominant cellular fatty acids [16 : 0, summed feature 3 (16 : 1ω7c and/or iso-15 : 0 2-OH) and 18 : 1ω7c], as well as biochemical and morphological analyses further support the designation of Neisseria wadsworthii sp. nov. (type strain 9715T =DSM 22247T =CIP 109934T) and Neisseria shayeganii sp. nov. (type strain 871T =DSM 22246T =CIP 109933T).

From a phlegmon in a dog an aerobic and facultatively anaerobic, indole-, oxidase- and catalase-negative, non-motile bacterium was isolated in 2019 in Germany that stained Gram-negative and showed a pleomorphic, rod-shaped, non-spore-forming appearance. Based on the results of 16S rRNA gene sequence analyses, strain IHIT1603-19T was assigned to the genus Streptobacillus with sequence similarities of 98.6, 98.0, 97.9, 97.1 and 94.4 % to the type strains of Streptobacillus felis , Streptobacillus notomytis , Streptobacillus ratti , Streptobacillus moniliformis and Streptobacillus hongkongensis , respectively. Strain IHIT1603-19T could also clearly be differentiated from other Streptobacillus species by rpoB, groEL and recA gene, nucleotide and amino acid sequence analyses as well as by core genome phylogeny. Regarding DNA–DNA relatedness, strain IHIT1603-19T demonstrated an average nucleotide identity of 83.00 and 82.28 % compared to S. felis 131000547T and S. moniliformis DSM 12112T, respectively. Chemotaxonomic and physiological data of strain IHIT1603-19T were in congruence with other closely related members of the family Leptotrichiaceae , represented by highly similar enzyme profiles and fatty acid patterns. MALDI-TOF MS analysis also proved suitable in unequivocally discriminating strain IHIT1603-19T from all currently described taxa of the genus Streptobacillus . On the basis of these data, we propose the novel species Streptobacillus canis sp. nov. with the type strain IHIT1603-19T (=DSM 110501T=CCUG 74118T=CIP 111795T). The G+C content of the DNA of the type strain is 26.6 mol%, genome size is 1.60 Mbp.

A small collection of carnivoran fossils from the South Turkwel hominid site is described. The fauna is composed of Megantereon ekidoit new species, Homotherium sp., Crocuta cf. dietrichi, cf. Pachycrocuta sp., Canis new species A., cf. Civettictis sp., Viverridae or Herpestidae indet., and Lutrinae indet. The record of Megantereon and Canis, as well as Pachycrocuta and Civettictis, if these genera are identified correctly, represents the earliest occurrences of their respective taxa in Africa. These specimens suggest a relatively rapid reorganization of the carnivore guild some time around 3.5 Ma, followed by a longer period of transition to a fauna more comparable in composition to the modern one.

Ehrlichia canis, Anaplasma platys, and Babesia vogeli are frequently detected in the veterinary routine with varied pathogenesis that can lead to death, mainly in co-infections. Although canine hemotropic mycoplasmas are considered of low clinical importance, they have recently gained prominence in molecular research. The present study aimed to analyze two hospital populations of dogs, randomly selected from the year 2013 and 2015, from the municipalities of Toledo (n=68) and Cascavel (n=107). Direct examination of blood smears, serology, and PCR were used to detect the presence of E. canis, A. platys, B. vogeli and Mycoplasma sp. Direct blood smear examination was negative for the investigated agents in all samples. Serum immunochromatography (SensPERT ™, VetAll Laboratories, Korea) in 175 animals showed that only 4% (n = 7) had anti-E. canis antibodies, while 60% (n = 105) were positive for Anaplasma sp. All PCR samples were negative for E. canis, while 18.28% (n = 32) were positive for A. platys, 3.42% (n = 6) positive for Babesia vogeli, and 7.41% (n = 13) positive for Mycoplasma sp. The study revealed the presence of A. platys in Toledo and Cascavel by PCR, which accentuates the need to monitor vector populations and usual hosts and to evaluate the potential risk of infection in humans.

Tick-borne haematozoans cause severe diseases in domestic animals, and some of them have zoonotic potential. The results of previous studies in Europe point to the important role of foxes in natural endemic cycles of several tick-borne pathogens, including protozoa. The aim of the present research was to acquire information on the prevalence and distribution of tick-borne protozoan parasites among foxes in Serbia. Legally hunted foxes from 14 localities throughout Serbia were analysed. Spleen samples were collected from 129 animals and tested for the presence of Babesia spp. and Hepatozoon spp. by PCR. In total, 79/129 (61.2%) of the tested foxes were positive for H. canis, while the presence of two Babesia species was confirmed: B. vulpes (37/129, 28.7%) and B. canis (1/129, 0.8%). Coinfection with B. vulpes and H. canis was present in 26/129 (20.2%) foxes and one animal (1/129, 0.8%) was co-infected by B. canis and H. canis. The results of this study indicate the important role of foxes in the epizootiology of B. vulpes and H. canis in the Republic of Serbia and stress the need for further research to clarify all elements of the enzootic cycle of the detected pathogens, including other reservoirs, vectors, and transmission routes.

A serological survey on Ehrlichia canis was conducted among dogs in the central area of the state of Rio Grande do Sul, where the tick Rhipicephalus sanguineus is a common parasite of dogs. Out of a total of 316 dogs attended at the veterinary teaching hospital in the municipality of Santa Maria, only 14 (4.43%) reacted positively to E. canis antigens in the indirect immunofluorescence assay, with the following endpoint titers: 80 (three dogs), 160 (five), 320 (four), 640 (one) and 1280 (one). Like in previous studies in other regions of the state of Rio Grande do Sul, only a very small portion of the dogs in Santa Maria presented antibodies reactive to E. canis, even though canine infestations due to R. sanguineus are very common in this study region. These results contrast with other regions of Brazil, where E. canis is endemic among canine populations, with seropositivity values generally higher than 30%. Genetic differences among the R. sanguineus populations in South America might be implicated in these contrasting results.

Minnesota wolves (Canis sp.) sometimes are reported to have affinity to a small, narrow-skulled eastern form ( Canis lupus lycaon Schreber, 1775) and sometimes to a larger, broader western form ( Canis lupus nubilus Say, 1823). We found that pre-1950 Minnesota wolf skulls were similar in size to those of wolves from southeastern Ontario and smaller than those of western wolves. However, Minnesota wolf skulls during 1970–1976 showed a shift to the larger, western form. Although Minnesota skull measurements after 1976 were unavailable, rostral ratios from 1969 through 1999 were consistent with hybridization between the smaller eastern wolf and the western form. Our findings help resolve the different taxonomic interpretations of Minnesota skull morphology and are consistent with molecular evidence of recent hybridization or intergradation of the two forms of wolves in Minnesota. Together these data indicate that eastern- and western-type wolves historically mixed and hybridized in Minnesota and continue to do so. Our findings are relevant to a recent government proposal to delist wolves from the endangered species list in Minnesota and surrounding states.

As doenças transmitidas por carrapatos são afecções de grande importância na clínica médica de pequenos animais, devido à alta casuística e ampla distribuição vetorial no território brasileiro. Os principais agentes responsáveis pelas infecções em cães são Babesia sp., Ehrlichia canis e Hepatozoon canis. Os animais infectados são assintomáticos ou apresentam sinais clínicos inespecíficos, sendo necessário a utilização de testes diagnósticos para definição do agente etiológico, e diagnóstico seguro. O objetivo do presente estudo foi determinar a ocorrência desses micro-organismos em cães naturalmente infectados, domiciliados nos municípios de Vila Velha e Anchieta, Espírito Santo, utilizando diferentes testes de detecção: Reação em cadeia polimerase (PCR), sorologia para detecção de anticorpos anti Ehrlichia canis e pesquisa de hematozoários em esfregaço sanguíneo. Foram analisadas 65 amostras de sangue obtidas por venopunção de veia cefálica de cães. No teste de PCR, 4,62% dos animais foram positivos para Babesia vogeli e 1,54% para Ehrlichia canis sendo os resultados para Hepatozoon canis negativos. No teste sorológico para E. canis 90,77% dos animais foram positivos para a presença de anticorpos, e na pesquisa em lâminas de esfregaço sanguíneo 3,02% apresentavam outros hemoparasitas. Os resultados indicam a dispersão desses hemoparasitas na população canina da região de estudo, entretanto com baixa ocorrência. O teste de PCR demonstrou-se como o mais sensível no qual Babesia vogeli foi o agente mais observado.

Abstract Recently, the importance of wild-living rodents for maintenance of pathogens of the family Anaplasmataceae in the environment was investigated. These mammals play a role as reservoirs for these pathogens and act as hosts for the immature stages of tick vectors. The aim of the present study was to investigate the prevalence of Ehrlichia sp. and Anaplasma sp. in 24 specimens of Azara’s agouti (Dasyprocta azarae) that had been trapped in the Itapiracó Environmental Reserve, in São Luís, Maranhão, northeastern Brazil, using molecular methods. Four animals (16.7%) were positive for Ehrlichia spp. in nested PCR assays based on the 16S rRNA gene. In a phylogenetic analysis based on the 16S rRNA gene, using the maximum likelihood method and the GTRGAMMA+I evolutionary model, Ehrlichia sp. genotypes detected in Azara’s agoutis were found to be closely related to E. canis and to genotypes relating to E. canis that had previously been detected in free-living animals in Brazil. The present work showed the first molecular detection of Ehrlichia sp. in Azara’s agoutis in Brazil.

Os ectoparasitos são capazes de transmitir patógenos incluindo algumas bactérias, como a Ehrlichia sp., causando doenças em animais domésticos. Pouco se conhece sobre a epidemiologia da erliquiose felina, embora alguns estudos já tenham sido realizados para elucidar a sua patogenia e transmissão. Este trabalho relata a primeira infecção mútua por Ehrlichia sp. entre um felino doméstico e o carrapato Rhipicephalus sanguineus sensu lato (s.l.) removido deste animal. Ambos foram testados pela Reação em Cadeia pela Polimerase (PCR) para detectar o gene dsb, e as sequências analisadas confirmaram amostras 100% idênticas à E. canis. Baseado neste relato é discutida a importância dos gatos como vetores de E. canis e sua posição no ciclo de transmissão de carrapatos entre cães e gatos no Brasil.

Background: We present a study about helminth parasites in wolf (Canis lupus signatus) from Sierra de la Culebra, a protected area in the Northwest of Spain, where is the largest population of wolves of the Spanish territory and one of the largest in Western Europe. Materials and Methods: To this aim, 93 fecal samples were collected during May and June of 2013 using 33% zinc sulphate flotation technique and classified based on their morphology, color, structure and size. Results: Parasites were present in 66.67% of the samples and classified as Eucoleus aerophilus (50.54%), Strongyloides sp. (27%), Ancylostomidae gen. sp. (19.35%), Toxocara Canis (10.75%), Taeniidae gen. sp. (9.68%), Trichuris vulpis (9.68%) and Toxascaris leonina (2.15%). Their distributions were very heterogeneous with the highest prevalence being in Northwest Spain. These differences found can be attributed to local environmental factors (ambient temperature, humidity) as well as animal feeding and social behavior. Conclusion: A wide helminthofauna is observed in the studied wolves, similar to other studies carried out in Europe (Estonia, Finland, Italy, Latvia, Poland, Portugal, Spain and Sweden). In addition, this study constitutes the first description of the presence of Strongyloides sp. in Iberian wolf in Spain.

Background: Livestock are key sources of livelihood among pastoral communities. Livestock productivity is chiefly constrained by pests and diseases. Due to inadequate disease surveillance in northern Kenya, little is known about pathogens circulating within livestock and the role of livestock-associated biting keds (genus Hippobosca) in disease transmission. We aimed to identify the prevalence of selected hemopathogens in livestock and their associated blood-feeding keds. Methods: We randomly collected 389 blood samples from goats (245), sheep (108), and donkeys (36), as well as 235 keds from both goats and sheep (116), donkeys (11), and dogs (108) in Laisamis, Marsabit County, northern Kenya. We screened all samples for selected hemopathogens by high-resolution melting (HRM) analysis and sequencing of PCR products amplified using primers specific to the genera: Anaplasma, Trypanosoma, Clostridium, Ehrlichia, Brucella, Theileria, and Babesia. Results: In goats, we detected Anaplasma ovis (84.5%), a novel Anaplasma sp. (11.8%), Trypanosoma vivax (7.3%), Ehrlichia canis (66.1%), and Theileria ovis (0.8%). We also detected A. ovis (93.5%), E. canis (22.2%), and T. ovis (38.9%) in sheep. In donkeys, we detected ‘Candidatus Anaplasma camelii’ (11.1%), T. vivax (22.2%), E. canis (25%), and Theileria equi (13.9%). In addition, keds carried the following pathogens; goat/sheep keds - T. vivax (29.3%), Trypanosoma evansi (0.86%), Trypanosoma godfreyi (0.86%), and E. canis (51.7%); donkey keds - T. vivax (18.2%) and E. canis (63.6%); and dog keds - T. vivax (15.7%), T. evansi (0.9%), Trypanosoma simiae (0.9%), E. canis (76%), Clostridium perfringens (46.3%), Bartonella schoenbuchensis (76%), and Brucella abortus (5.6%). Conclusions: We found that livestock and their associated ectoparasitic biting keds carry a number of infectious hemopathogens, including the zoonotic B. abortus. Dog keds harbored the most pathogens, suggesting dogs, which closely interact with livestock and humans, as key reservoirs of diseases in Laisamis. These findings can guide policy makers in disease control.

The canine population in the cities of Ciénaga and Santa Marta has been estimated at 54,953 based on individual dogs with owners. Due to the role that dogs play in society, either as pets or as transmitters of zoonoses to humans, we conducted a study with 169 blood samples from dogs that visited two veterinary clinics in these locations between March and September of 2017. The objective of the study was to detect species of Babesia and Hepatozoon canis by amplifying the 18S gene using conventional polymerase chain reaction (PCRc). The presence of Babesia sp. and Hepatozoon canis was detected in 15 (8.87%) and 12 (7.10%) DNA samples, respectively. In addition, 7 (4.14%) cases of coinfection were recorded. The Babesia sp. sequences obtained corresponded to the B. canis vogeli subspecies. This both pathogens in the Colombian Caribbean region and cases of coinfection in Colombian dogs. Therefore, the national veterinary community is encouraged to consider the information presented here in their differential diagnoses associated with companion vector-borne diseases (CVBDs). This information will allow veterinary professionalsto create control and prevention strategies to prevent the spread of these infections.

Tick-borne pathogens affect a wide range of vertebrate hosts. To identify tick-borne pathogens among dogs from Campo Grande, MS, Brazil testing seropositive for Leishmania infantum (syn. L. chagasi), a serological and molecular study was conducted to detectEhrlichia canis, Anaplasma platys and Babesia vogeli in 60 serum and spleen samples. A confirmatory diagnosis ofL. infantum based on serological and molecular assays was also performed, as was sequence alignment and phylogenetic analysis to assess the identity of the parasite species infecting these animals. IgG antibodies toEhrlichia spp., B. vogeli and L. infantum were found, respectively, in 39 (65%), 49 (81.6%) and 60 (100%) of the sampled dogs. Twenty-seven (45%), fifty-four (90%), fifty-three (88.3%), two (3.3%) and one (1.6%) dog were positive, respectively, forE. canis, Leishmania spp., Leishmania donovani complex, Babesia sp. and Anaplasma sp. in PCR assays. After sequencing, the amplicons showed 99% of identity with E. canis, B. vogeli, A. platys andLeishmania chagasi isolates. The findings of this study indicate that L. infantum-seropositive dogs from Campo Grande are exposed to multiple tick-borne pathogens, which should therefore be included in the differential diagnosis of dogs with clinical suspicion of leishmaniasis.

SUMMARYRed fox (Vulpes vulpes) is the most abundant wild canid species in Austria, and it is a well-known carrier of many pathogens of medical and veterinary concern. The main aim of the present study was to investigate the occurrence and diversity of protozoan, bacterial and filarial parasites transmitted by blood-feeding arthropods in a red fox population in western Austria. Blood (n= 351) and spleen (n= 506) samples from foxes were examined by PCR and sequencing and the following pathogens were identified:Babesia canis,Babesiacf.microti(syn.Theileria annae),Hepatozoon canis,Anaplasma phagocytophilum,CandidatusNeoehrlichia sp. andBartonella rochalimae. Blood was shown to be more suitable for detection ofBabesiacf.microti, whilst the spleen tissue was better for detection ofH. canisthan blood. Moreover, extremely low genetic variability ofH. canisand its relatively low prevalence rate observed in this study may suggest that the parasite has only recently been introduced in the sampled area. Furthermore, the data presented here demonstrates, for the first time, the possible vertical transmission ofH. canisfrom an infected vixen to the offspring, and this could explain the very high prevalence in areas considered free of its main tick vector(s).

Os animais são transmissores de vários parasitos que podem ocasionar doenças conhecidas como zoonóticas, podendo causar grande impacto na vida dos seres humanos e na vida do próprio animal com muitos prejuízos a ambos. Assim, este trabalho objetivou verificar a prevalência das principais doenças parasitárias com potencial zoonótico na região de Leopoldina, cidade situada no interior do Estado de Minas Gerais. Trata-se de um estudo descritivo, retrospectivo, realizado em um laboratório veterinário particular no período de janeiro a dezembro de 2017. Neste estudo, foram analisadas 109 amostras de fezes de cães das quais 57 foram positivas para alguma parasitose. Das amostras investigadas, 38 evidenciaram infecções únicas e 19 infecções múltiplas. Foram identificados 23 helmintos e 57 protozoários, totalizando 80 diferentes espécies, destas 29 foram de Giardia sp, 28 foram de Isospora canis, 16 de Ancylostoma sp, quatro de Strongyloides stecoralis uma de Toxocara canis, uma de Taeniidae e uma de Uncinaria sp. As análises revelaram a presença de parasitas de potencial zoonótico, sendo esses Giardia sp, seguida por Ancylostoma sp, Strongiloides stecoralis e Uncinaria sp. Com esses resultados se pode concluir a necessária importância de medidas de prevenção primária a saúde para devida conscientização da população e profissionais veterinários e de saúde qualificados para que possam auxiliar no diagnóstico e, consequentemente, na redução do índice dessas parasitoses e na causa de doenças debilitantes aos humanos e animais.

A Erliquiose canina é uma zoonose causada pela Ehrlichia canis, bactéria Gram negativa de distribuição mundial. Alguns cães com erliquiose se tornam portadores assintomáticos enquanto outros desenvolvem uma doença aguda com morte rápida. A apoptose pode ser importante na eliminação de patógenos intracelulares, podendo, nas infecções por Ehrlichia sp. e Anaplasma sp., ocorrer modulação da apoptose celular para prolongar a sobrevivência desses organismos. Para avaliação do papel da apoptose na erliquiose canina, sete cães foram distribuídos em dois grupos. No Grupo inoculado, realizou-se a infecção por via intravenosa com sangue infectado com E. canis (isolado Jaboticabal), sendo realizada a inoculação com PBS estéril nos animais pertencentes ao Grupo Controle. Semanalmente e até 35 dias pós-inoculação, amostras de sangue foram coletadas e submetidas a n-PCR e reação de imunofluorescência (RIFI) para confirmação da infecção. No 36° dia pós-inoculação, os animais foram eutanasiados, sendo as amostras de baço, linfonodo, rim e fígado coletadas e processadas para as técnicas de TUNEL e imunohistoquímica (Bcl-2, Bax). Verificou-se pela n-PCR que os animais inoculados se tornaram positivos para E. canis a partir da segunda semana. Pela RIFI, verificou-se animais com sorologia positiva a partir da terceira semana pós-inoculação. No grupo controle, todos os testes realizados foram negativos para E. canis. Apesar da reação de TUNEL mostrar maior incidência de apoptose no Grupo Inoculado, sendo o baço e os linfonodos os órgãos que apresentaram maior marcação, os resultados da imunohistoquímica para Bcl-2 e Bax indicam que a via intrínseca de apoptose não é importante nos órgãos analisados.

The bacteria of the families Rickettsiaceae and Anaplasmataceae, harbored by arthropod vectors, may cause disease in animals and humans. The aim of this study was to screen ectoparasites collected from cats and dogs in Attica, Greece for the bacteria of the Rickettsiales group, by molecular methods. The ectoparasites examined were Ctenocephalides felis fleas and Rhipicephalus sanguineus s.l., Rhipicephalus sp., and Ixodes sp. ticks. Rickettsia felis was detected in 4.8% of C. felis fleas, and Rickettsia conorii was detected in 7.3% of R. sanguineus s.l. ticks. Ehrlichia canis was found in one R. sanguineus s.l. tick, and Wolbachia pipientis was detected in the majority of fleas. Another endosymbiont, Cancidatus Midichloria mitochondrii (Cancidatus Midichloriaceae), was detected in one Ixodes sp.. This is the first report of R. conorii and E. canis in R. sanguineus s.l. ticks in this study area. Given the fact that Greece is considered endemic for spotted fever group rickettsioses, further investigation of these rickettsial pathogens’ distribution in their vectors and hosts could enhance our knowledge of their epidemiology, in order to assess their potential implications for public health in this metropolitan area.

Resumo: Os animais silvestres são hospedeiros de uma grande variedade de parasitos que podem interferir em sua conservação ex situ. O objetivo deste estudo foi identificar os parasitos gastrointestinais (PGI) e ectoparasitos dos animais do Centro de Triagem de Animais Silvestres (CETAS) do Instituto Brasileiro de Meio Ambiente e Recursos Naturais Renováveis (IBAMA) de Recife, Pernambuco, além de determinar os aspectos do manejo em cativeiro que possam estar relacionados com os parasitos identificados. Foram coletados ectoparasitos e amostras fecais de 223 aves e mamíferos, as quais foram processadas pelos métodos: microscopia direta, flutuação e sedimentação. Helmintos e/ou protozoários foram detectados em 91 (40,8%) amostras fecais, sendo 64 (70,3%) de aves e 27 (29,7%) de mamíferos. Ovos de Capillaria sp., Ascaridida, Spirurida e oocistos de Eimeria sp. foram detectados nas amostras fecais das aves, enquanto ovos de Trichuris trichiura, Strongyloides sp., Toxocara canis, Ancylostoma sp., Strongylida e oocistos de Coccídios foram encontrados nas amostras fecais de mamíferos. Os ectoparasitos identificados em aves foram Colpocephalum turbinatum, Kurodaia (Kurodaia) fulvofasciata, Halipeurus sp., Naubates sp., Saemundssonia sp., Austromenopon sp., Paragoniocotes sp., Brueelia sp., Myrsidea sp. and Pseudolynchia sp., enquanto em mamíferos os ectoparasitos identificados foram Rhipicephalus sanguineus, Amblyomma varium, A. calcaratum, A. nodosum, Ornithodoros talaje e Ctenocephalides felis felis. A. calcaratum e O. talaje são registrados pela primeira vez em Pernambuco e T. tetradactyla é apresentado como novo hospedeiro de O. talaje. Nenhum dos animais estudados apresentou sinais clínicos em decorrência da infecção/infestação parasitária. Parasitos com potencial zoonótico como T. trichiura, Strongyloides sp., T. canis e Ancylostoma sp. foram identificados em primatas não humanos e carnívoros. Precárias condições estruturais e sanitárias do CETAS-PE estão relacionadas com os parasitos identificados neste estudo e devem ser levadas em consideração para a adoção de medidas adequadas de controle. Os resultados deste estudo contribuirão de maneira significativa para a conservação de animais selvagens no CETAS-PE e para a saúde dos profissionais responsáveis pela manutenção destes animais.

AbstractTwenty species of helminth parasites were identified from fox, wolf, jackal and wild cat material collected in Greece. Of the 314 foxes (Vulpes vulpes) examined, 18 helminth species were recovered comprising one trematode, eight cestodes, seven nematodes and two acanthocephalans, with the cestode species Mesocestoides sp. (73.2%), Joyeuxiella echinorhynchoides (24.5%) and the nematode species Uncinaria stenocephala (43.9%), and Toxocara canis (28.6%) being the most prevalent. Five cestode and three nematode species were reported from six wolves (Canis lupus), together with one trematode, three cestode and four nematode species from five jackals (Canis aureus) and two cestode and three nematode species from four wild cats (Felis silvestris) examined. The species J. echinorhynchoides, Taenia crassiceps and Onicola canisand the genera Spirometra, Rictularia and Pachysentis are reported here for the first time in Greece. The results are discussed in the light of the feeding characteristics of wild carnivores in rural areas of Greece.

Four strains, KC07070T, KC07105, 11 025B-8C and 11 026B-8-C, were isolated from the oral cavity of cats in 2007 or 2011 in Japan. These strains were Gram-stain-negative rods, exhibited gliding motility, grew in air with 5 % CO2 and showed catalase and oxidase activity. The sequences of 16S rRNA genes of the four strains were 100 % identical. Additionally, the sequences of 16S rRNA genes of KC07070T had identity to those of the type strains of Capnocytophaga canimorsus (97.7 %), Capnocytophaga cynodegmi (97.8 %) and Capnocytophaga canis (97.4 %) and 91.2–93.8% identity to those of other species of the genus Capnocytophaga . The major cellular fatty acids of KC07070T were iso-C15 : 0 (56.2 %) and summed feature 11 (14.9 %). The G+C content of the DNA from KC07070T was 35.6 mol%, and the genome size was 2.88 Mbp. KC07070T had digital DNA–DNA hybridization (dDDH) values of 26.2–27.6% and average nucleotide identity (ANI) values of 75.4–83.3 % to the type strains of the closest relatives, C. canimorsus , C. cynodegmi and C. canis . These results of phylogenetic analysis of 16S rRNA gene sequence, cellular fatty acids compositions and dDDH and ANI values indicate that strain KC07070T represents a novel species, for which we propose the name Capnocytophaga felis sp. nov., with type strain KC07070T (=JCM 32681T=DSM 107251T).

Ehrlichiosis is a tick-borne disease that affects both humans and animals. The few existing reports on ehrlichiosis in Brazilian cats have been based on observation of morulae in leukocytes and, more recently, on molecular detection of Ehrlichia sp. In this study, we assessed occurrences of Ehrlichia sp. in the blood of 200 domestic cats in São Luís, Maranhão. Of the 200 animals tested, 11 (5.5%) were seropositive for Ehrlichia sp. and two (1%) were positive for Ehrlichia sp. in PCR. We also performed DNA sequence alignment to establish the identity of the parasite species infecting these animals, using the gene 16S rRNA. One cat presented infection with Ehrlichia sp. with 98% identity with E. canis, and another cat infected with Ehrlichia sp. showed 97% identity with E. chaffeensis. This is the first study on molecular detection of Ehrlichia sp. among domestic cats in São Luís, Maranhão.
