Abstract:
It is estimated that vibriosis account for about half of the economic losses in Asian fish culture. Consequently, the prevention and control of vibriosis is one of the priority research topics in the field of Asian fish culture disease. Relevant measures have been proposed to control some Vibrios that pose a threat to Asian fish culture, but there are currently only a few effective vaccines available to combat these Vibrios. The purpose of our review is to sum up the main prevention methods and the latest control strategies of seven Vibrio species that cause great harm to Asian aquaculture, including Vibrio harveyi, Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio mimicus, Vibrio anguillarum, Vibrio alginolyticus and Vibrio cholerae. Strategies such as antibiotics, probiotics, bacteriophages, antimicrobials from plants and other natural sources, as well as vaccines, are compared and discussed here. We expect this review will provide some new views and recommendations for the future better prevention and control of vibriosis in Asian fish culture.

Abstract:
Vibrio alginolyticus and V. parahaemolyticus, the causative agents of Vibriosis in marine vertebrates and invertebrates, are also responsible for fatal illnesses such as gastroenteritis, septicemia, and necrotizing fasciitis in humans via the ingestion of contaminated seafood. Aquaculture farmers often rely on extensive prophylactic use of antibiotics in farmed fish to mitigate Vibrios and their biofilms. This has been postulated as being of serious concern in the escalation of antibiotic resistant Vibrios. For this reason, alternative strategies to combat aquaculture pathogens are in high demand. Bacteriophage-derived lytic enzymes and proteins are of interest to the scientific community as promising tools with which to diminish our dependency on antibiotics. Lysqdvp001 is the best-characterized endolysin with lytic activity against multiple species of Vibrios. Various homologues of Vibrio phage endolysins have also been studied for their antibacterial potential. These novel endolysins are the major focus of this mini review.

Abstract:
This study analysed the usefulness of recA gene sequences as an alternative phylogenetic and/or identification marker for vibrios. The recA sequences suggest that the genus Vibrio is polyphyletic. The high heterogeneity observed within vibrios was congruent with former polyphasic taxonomic studies on this group. Photobacterium species clustered together and apparently nested within vibrios, while Grimontia hollisae was apart from other vibrios. Within the vibrios, Vibrio cholerae and Vibrio mimicus clustered apart from the other genus members. Vibrio harveyi- and Vibrio splendidus-related species formed compact separated groups. On the other hand, species related to Vibrio tubiashii appeared scattered in the phylogenetic tree. The pairs Vibrio coralliilyticus and Vibrio neptunius, Vibrio nereis and Vibrio xuii and V. tubiashii and Vibrio brasiliensis clustered completely apart from each other. There was a correlation of 0·58 between recA and 16S rDNA pairwise similarities. Strains of the same species have at least 94 % recA sequence similarity. recA gene sequences are much more discriminatory than 16S rDNA. For 16S rDNA similarity values above 98 % there was a wide range of recA similarities, from 83 to 99 %.

Abstract:
Several Vibrio species have been implicated in diarrheal diseases and wound infection, and some foods are important vehicles for these pathogens. A number of these vibrios isolated from food produced extracellular heat-labile or heat-stable hemolysin and cytotoxins, but only a few strains hybridized to nucleic acid probes of Shiga-like toxin, cholera toxin, or thermostable direct hemolysin. These vibrios also produced extracellular or cell-mediated mouse-lethal factors. The vibrios from foods may produce toxins not identical or related to the common toxins of Escherichia coli, Vibrio cholerae, or Vibrio parahaetnolyticus.

Abstract:
Pathogenic vibrios are important etiologic agents in tropical regions and have been frequently recovered from seafoods and aquacultured foods. In this study, commercially frozen seafoods including peeled shrimps and fish and shrimp dumplings were examined. Vibrio alginolyticus, Vibrio parahaemolyticus, Vibrio cholerae and Vibria fluvialis were recovered at 36.0%, 15.8%, 14.9% and 13.2%, respectively. A number of psychrotrophic vibrios were selected and their survival in tryptic soy broth (TSB) supplemented with 1% sodium chloride (NaCl) (TSBS medium) and shrimp homogenate at 4°C and −30°C were studied. Two psychrotrophic non-O1 V. cholerae (laboratory stocks no 128 and 129) survived well at these low temperatures. Counts decreased by about 1 log/ml in TSBS medium at 4°C for 6 days and 3 log/ml at −30°C for 3 days. Shrimp homogenate provided better protection than TSBS medium for psychrotrophic V. cholerae at −30°C. Survival of V. cholerae at low temperatures was further increased by the addition of 0.5% of heated pyrophosphate and metaphosphate, probably by decreasing the lethality of the cold injury to the cells. Measures should be taken to minimize the risk from pathogenic vibrios in frozen seafoods, especially if phosphates are used and psychrotrophic strains are present.

Typing and identification of 60 marine psychrophilic and psychrotrophic vibrios isolated from the north-western Pacific Ocean and coastal environment of Japan were performed by restriction fragment length polymorphism analysis on the basis of polymerase chain reaction amplified 16S rDNA. We obtained 15 operational taxonomic units (OTUs) by digestion with four restriction endonucleases (HhaI, DdeI, RsaI, and Sau3AI); four large groups were obtained from the neighbor-joining method. Significant differences were observed in OTU composition between isolates from the deep sea and coastal areas. Vibrio marinus and Photobacterium species were the dominant culturable vibrios in the deep sea areas, while Vibrio splendidus like species were the dominant culturable vibrios in a coastal area of Japan.Key words: restriction analysis, Vibrio, Photobacterium, Vibrio marinus (Moritella marina), Vibrio splendidus.

Abstract:
Vibrios are halophilic bacteria that are ubiquitous in marine environments. Their occurrence in tropical lakes has rarely been investigated. In this study, the predominance and diversity of Vibrio spp. was investigated over a 12-month period in a coastal lagoon, Songkhla Lake, in southern Thailand. Water samples were collected at 2 stations in the estuary near Yor Island in Songkhla Lake. The predominant vibrios were detected by a culture-based method, using thiosulfate–citrate–bile salt–sucrose agar and CHROMagar Vibrio. The diversity of Vibrio spp. was evaluated using denaturant density gradient electrophoresis (DGGE). The highest numbers of total vibrios and Vibrio parahaemolyticus in both areas were observed during the summer. There was no significant correlation between the numbers of vibrios, including V. parahaemolyticus, and either the water temperature or plankton density. Variations in Vibrio species were observed with changes in salinity. Vibrio parahaemolyticus and V. cholerae non-O1/non-O139 were detected during the rainy season when the salinity dropped to nearly 0 parts per thousand. In both areas, V. alginolyticus was the most prominent species detected by the culture method, whereas Vibrio parahaemolyticus was detected by DGGE, every month. Other Vibrio spp. of potential public health concern were also detected by the culture method; they included V. vulnificus , V. fluvialis , and V. mimicus .

Abstract:
Vibrios are ubiquitous in the aquatic environment and can be found in association with animal or plant hosts. The range of ecological relationships includes pathogenic and mutualistic associations. To gain a better understanding of the ecology of these microbes, it is important to determine their phenotypic features. However, the traditional phenotypic characterization of vibrios has been expensive, time-consuming and restricted in scope to a limited number of features. In addition, most of the commercial systems applied for phenotypic characterization cannot characterize the broad spectrum of environmental strains. A reliable and possible alternative is to obtain phenotypic information directly from whole genome sequences. The aim of the present study was to evaluate the usefulness of whole genome sequences as a source of phenotypic information. We performed a comparison of the vibrio phenotypes obtained from the literature with the phenotypes obtained from whole genome sequences. We observed a significant correlation between the previously published phenotypic data and the phenotypic data retrieved from whole genome sequences of vibrios. Analysis of 26 vibrio genomes revealed that all genes coding for the specific proteins involved in the metabolic pathways responsible for positive phenotypes of the 14 diagnostic features (Voges–Proskauer reaction, indole production, arginine dihydrolase, ornithine decarboxylase, utilization of myo-inositol, sucrose and l-leucine, and fermentation of d-mannitol, d-sorbitol, l-arabinose, trehalose, cellobiose, d-mannose and d-galactose) were found in the majority of the vibrios genomes. Vibrio species that were negative for a given phenotype revealed the absence of all or several genes involved in the respective biochemical pathways, indicating the utility of this approach to characterize the phenotypes of vibrios. The absence of the global regulation and regulatory proteins in the Vibrio parahaemolyticus genome indicated a non-vibrio phenotype. Whole genome sequences represent an important source for the phenotypic identification of vibrios.

Abstract:
Vibrio is a genus of ubiquitous heterotrophic bacteria found in aquatic environments. Although they are a small percentage of the bacteria in these environments, vibrios can predominate during blooms. Vibrios also play important roles in the degradation of polymeric substances, such as chitin, and in other biogeochemical processes. Vibrios can be found as free-living bacteria, attached to particles, or associated with other organisms in a mutualistic, commensal, or pathogenic relationship. This review focuses on vibrio ecology and genome plasticity, which confers an ability to adapt to new niches and is driven, at least in part, by horizontal gene transfer (HGT). The extent of HGT and its role in pathogen emergence are discussed based on genomic studies of environmental and pathogenic vibrios, mobile genetically encoded virulence factors, and mechanistic studies on the different modes of HGT.

Abstract:
Genomas de vibrios ambientais ainda são pouco conhecidos. O presente trabalho de dissertação de mestrado envolveu a anotação de quatro genomas parciais de vibrios ( V. alginolyticus 40B, V. communis 1DA3, V. mimicus VM603 e VM573), a comparação da performance de três sistemas automáticos de anotação de genomas (SABIA, RAST, e GRC) e a determinação de genes putativos únicos de cada um dos quatro genomas. Os genomas de vibrios apresentaram entre 3.745 e 4.977 genes, dos quais em média 2.900 são válidos, 898 são conservados hipotéticos e 385 são hipotéticos. Os genomas apresentaram similaridade em termos de classes de grupos ortólogos com a maioria dos genes válidos identificados nas classes: funções gerais e desconhecidas(R e S), transporte e metabolismo de aminoácidos(E) e transcrição(K) de acordo com as classes de grupos ortólogos (COG) e a maioria das classes foram similares. A comparação entre os anotadores automáticos sugeriu que cada anotador apresenta prós e contras. O anotador SABIA apresenta uma grande interatividade com os bancos de dados biológicos, tais como o InterPro e Swiss-Prot. O anotador RAST é muito útil para comparação genômica do organismo de interesse com os diversos genomas e metagenomas presentes nos bancos públicos, enquanto que o anotador GRC pode ser utilizado localmente, sem a necessidade de acesso à internet. De acordo com as análises comparativas por meio da anotação realizada com o auxílio do BLAST e BLAST Atlas, os genomas de vibrios ( V. alginolyticus 40B, V. communis 1DA3, V. mimicus VM603 e VM573) também apresentaram diferenças em termos de conteúdo gênico, indicando que cada linhagem de vibrio possui sub-grupos de genes únicos. Cada um dos quatro genomas apresentaram de 289 a 1.6432 genes únicos de acordo com o as comparações pareadas com os vizinhos filogenéticos mais próximos disponíveis nos bancos de dados. Assim, a comparação entre os genomas das linhagens V. alginolyticus 40B e V. alginolyticus 12G01 resultou na descoberta de 541 genes únicos na linhagem V. alginolyticus 40B. A comparação entre os genomas de V. communis 1DA3 e V. campbellii ATTC BAA-1116 resultou na descoberta de 1.432 genes únicos na linhagem V. communis 1DA3 e a comparação entre os genomas de V. mimicus VM603 e VM573 resultou na descoberta de 334 e 289 genes únicos, em cada uma destas linhagens. Há um predomínio de genes únicos, sobretudo, pertencentes as classes relacionadas com carboidratos, resposta ao estresse, virulência, aminoácidos e derivados, parede celular e cápsula, sugerindo que estes genes estariam associados com a adaptação das linhagens à diferentes condições ambientais e diferentes nichos ecológicos.
Vibrios genomes are not fully known. This thesis focused on the annotation of four draft genomes ( V. alginolyticus 40B, V. communis 1DA3, V. mimicus VM603 e VM573), the performance comparison of three automated genome annotations (SABIA, RAST and GRC) and the identification of putative unique genes (strain specific genes) in the genomes. The genomes of Vibrios contained between 3,745 and 4,977 genes, of which 2,900 were real genes, 898 were hypothetic conserved genes and 385 were hypothetic genes. The majority of known gene products were related to general functions and unknown functions (R and S), metabolism and amino acid transport (E) and transcription (K) on the basis of the COG (clusters of ortologs group). The comparison of three automated genome annotation systems indicated that each system had advantages and disadvantagens. The SABIA Server revealed interactivity with many biologic databases, such as InterPro and Swiss-Prot. The RAST server was useful for comparative genomics of specific genomes and metagenomes. The GRC server was useful annotation offline as it can be installed and run on a local computer. The genomes of Vibrios showed differences in the genic content revealled by BLAST atlas and BLAST. Each genome showed 289 to 1,432 unique genes, resulting of comparisons with organisms phylogenetically closest related. The comparison of the genomes of V. alginolyticus 40B and V. alginolyticus 12G01 revealed that 40B has 541 unique genes. The comparison of V. communis 1DA3 and V. campbellii ATTC genome revealed 1,432 unique genes in 1DA3. V. mimicus VM573 and VM603 genomes showed 334 and 289 unique genes, respectively. The vast majority of unique genes were related with carbohidrates, stress response, virulence, cell wall and capsule, indicating that this sub-group of genes may be associated with adaptation of strains to differents habitats and ecologic niches.

Vibrios sao bacterias amplamente distribuidas no meio aquatico e podem ser encontradas em associacao com organismos marinhos, tanto como causadores de doencas quanto como simbiontes. O advento das tecnicas de sequenciamento de nova geracao e de alto desempenho tem possibilitado o acesso cada vez mais amplo a dados genomicos microbianos, incluindo vibrios. Tal quantidade e disponibilidade de dados permitem analises in silico, que podem compreender desde caracteristicas genomicas ate fenotipicas. A taxonomia microbiana e fundamentada na abordagem polifasica, que mede as relacoes evolutivas a partir do uso de sequencias de genes, especialmente o RNAr 16S, similaridade genomica, por meio de hibridizacao de DNA, e ampla caracterizacao fenotipica. A caracterizacao fenotipica requer testes experimentais, que muitas vezes sao demorados, caros e requerem grande experiencia. Neste estudo propomos o uso de genomas para a analise da diversidade e identificacao fenotipica de vibrios. Para tanto, foram avaliadas caracteristicas basicas de vibrios (tais como tamanho do genoma, conteudo genico e posicao logenetica); analisaram-se genes unicos e suas possiveis funcoes ecologicas; e desenvolveu-se uma ferramenta prototipo para identificacao de fenotipos diagnosticos de vibrios, denominada vibriophenotyping 1.0. A logenia construida a partir do genoma minimo recuperou os diferentes generos e clados descritos na literatura para o grupo vibrio, bem como posicionou as especies consideradas irmas em relacao a um ancestral comum proximo. Os genes unicos, por sua vez, puderam ainda revelar peculiaridades entre especies irmas. Por m, o programa de identificacao fenotipica desenvolvido foi testado com genomas de linhagens tipo de vibrios e apresentou uma media de similaridade superior a 70% entre os fenotipos obtidos in vitro e in silico, sendo alcançada uma similaridade de 100% para genomas integros. Dessa forma, concluiu-se que analises do pangenoma permitem a recontrucao logenetica dentro do grupo vibrios e a identificacao de genes unicos relevantes para o papel ecologico da especie no ambiente de origem, e, ainda, que a identificacao fenotipica atraves da automatizacao por uma ferramenta computacional e possivel a partir da analise de genomas.

La practica prolongada fue realizada en Departamento de Microbiología de Alimentos del Instituto se Salud Pública de Chile, durante los meses de Junio a Diciembre del año 2005. Mi labor en la práctica constó de tres etapas simultáneas: La primera consistió en recibir capacitación durante todo el período de mi práctica, en detección y cuantificación de los patógenos bacterianos más frecuentes encontrados en alimentos. La segunda etapa fue implementar el último método de detección de Vibrios (principalmente Vibrio vulnificus en mi caso) según el Manual Analítico Bacteriológico (BAM) año 2004 impuesto por la Food and Drugs Administration (FDA) (1), para la cual se utilizaron cepas de diversos Vibrios tales como Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio cholerae, etc. Dicha labor será necesaria para actualizar los métodos de detección en los laboratorios de la red de vigilancia epidemiológica de Chile. En la otra etapa, se evaluó según el método que se estaba desarrollando la población de Vibrio vulnificus existente en Puerto Montt, ésta etapa se comenzó a trabajar a partir aproximadamente en julio ya que primero debía estar desarrollada en alguna medida la técnica de detección, además de que estuvieran los materiales necesarios para el trabajo. Las muestras analizadas son ensayos de rutina que llegan al SEREMI de Salud de la región Metropolitana para evaluar durante todo el año la población de Vibrio parahaemolyticus y Vibrio cholerae en Puerto Montt, las cuales se reciben todos los martes y consta de 5 muestras de los cuales se analizan 12 especimenes de cada una, para luego cuantificarlas por el método de tubos múltiples según la tabla de número más probable (anexo, Tabla 1). Es importante que el ISP, como centro de referencia posea información sobre todo patógeno que pueda ser encontrado en alimentos, es por eso que esta etapa culminará con la entrega del procedimiento de detección de Vibrio vulnificus al Departamento de Microbiología de Alimentos

Abstract:
Les amibes libres dans les environnements aquatiques utilisent la phagocytose des bactéries pour leur nutrition. Selon l’hypothèse de l’évolution fortuite de la virulence, les mécanismes cellulaires et moléculaires de la phagocytose étant conservés des amibes aux cellules immunitaires des animaux, la prédation exercée par les amibes pourraient favoriser l’émergence de bactéries pathogènes résistantes à la phagocytose. Depuis 2008, les huîtres creuses Crassostrea gigas sont victimes d’épisodes de surmortalités en France. Cette pathologie poly-microbienne implique le virus Herpes OsHV-1 µvar qui provoque une immunosuppression des huîtres qui sont alors colonisées par divers bactéries pathogènes opportunistes dont des vibrios induisant la mort de l’animal. V. tasmaniensis LGP32 est un pathogène intracellulaire facultatif des hémocytes d’huître qui résiste à la phagocytose et détruit les hémocytes en utilisant un certain nombre de facteurs de virulence. Nous avons donc entrepris d’étudier les interactions entre les amibes libres de l’environnement ostréicole et les vibrios afin de vérifier si certains mécanismes de virulence pouvaient aussi jouer un rôle dans ce type d’interactions. En réalisant des échantillonnages sur le terrain, nous avons mis en évidence que l’interaction entre vibrios et amibes est écologiquement réaliste, et observé une faible diversité de protistes hétérotrophes près des tables ostréicoles de la lagune de Thau par rapport à d’autres environnements moins anthropisés. Des études fonctionnelles entre LGP32 et l’amibe Vannella sp. AP1411 ont montré que LGP32 est capable de résister à la prédation par les amibes impliquant certains facteurs de virulence comme la métalloprotéase Vsm et la pompe d’efflux du cuivre de type P-ATPase CopA qui sont aussi impliqués dans l’interaction de LGP32 avec les huîtres. En revanche, d’autres facteurs de virulence impliqués chez l’huître ne le sont pas dans la résistance à la prédation par les amibes indiquant que certains facteurs sont impliqués dans des interactions avec divers hôtes tandis que d’autres seraient impliqués dans des interactions plus spécifiques
Free living amoebae inhabit aquatic environments and use phagocytosis of bacteria for their nutrition. According to the hypothesis of coincidental evolution of virulence, the cellular and molecular mechanisms of phagocytosis being preserved from amoebae to the immune cells of animals, the predation exerted by amoebae could favor the emergence of pathogenic bacteria resistant to phagocytosis. Since 2008, Crassostrea gigas oysters have suffered from over-mortality in France. This poly-microbial disease involves the Herpes OsHV-1 μvar virus which causes an immunosuppression of oysters that are then colonized by various opportunistic pathogenic bacteria including vibrios inducing the death of the animal. V. tasmaniensis LGP32 is a facultative intracellular pathogen of oyster hemocytes that resists phagocytosis and destroys hemocytes using different virulence factors. We have therefore undertaken to study the interactions between marine amoebae of the oyster environment and the vibrios in order to verify if some mechanisms of virulence could also play a role in this type of interactions. By performing field sampling, we demonstrated that the interaction between vibrios and amoebae is ecologically realistic and observed a low diversity of heterotrophic protists near the oyster tables of the Thau Lagoon compared to other less anthropogenic environments. Functional studies between LGP32 and the amoeba Vannella sp. AP1411 showed that LGP32 is able to resist amoeba predation involving certain virulence factors such as Vsm metalloprotease and CopA P-ATPase copper efflux pump which are also involved in the interaction of LGP32 with oysters. In contrast, other virulence factors implicated in the oyster are not involved in amoeba-predation resistance indicating that some factors are involved in interactions with various hosts while others would be involved in more specific interactions

Toutefois, sous l'influence de stress biotiques ou abiotiques une dysbiose se crée favorisant la prolifération d'espèces opportunistes de Vibrio qui peuvent induire la mort des huîtres. C’est notamment le cas lors du syndrome de mortalité des huîtres du Pacifique (POMS) provoqué par un virus immunosuppresseur, OsHV-1 µvar. Nous avons ici caractérisé les interactions Vibrio / C. gigas en contexte sain et pathologique. Nous montrons que chez des populations de V. splendidus associées à des huîtres saines, la virulence et la capacité de colonisation peuvent être contraintes par la sélection de structures de l’antigène O qui sont plus facilement reconnues par le système immunitaire de l'hôte mais qui confèrent une résistance au broutage par des amibes marines. Ce compromis entre la capacité à coloniser son hôte et la persistance environnementale est vraisemblablement à l’origine de la grande diversité structurale observée pour l’antigène O dans cette espèce. En contexte pathologique, nous avons montré que les espèces associées à l’huître sont en grande majorité cytotoxiques pour les cellules immunitaires de leur hôte, et ce, quel que soit l’environnement considéré (Atlantique, Méditerranée). Cette cytotoxicité est un déterminant clé de l’échappement aux puissantes défenses cellulaires de l’huître et du succès infectieux. Nous avons observé que les bases moléculaires de la cytotoxicité sont spécifiques à chaque espèce de Vibrio étudiée. Enfin, au-delà des agents pathogènes opportunistes qui utilisent la cytotoxicité (V. tasmaniensis, V. crassostreae, V. splendidus, V. harveyi), nous avons identifié de simples opportunistes, comme V. rotiferianus, qui non seulement bénéficient de l'activité immunosuppressive des autres agents pathogènes mais également adoptent des stratégies d'acquisition non coopérative de biens publics, tels que les sidérophores produits par la communauté microbienne hébergée par leur hôte
Bacteria of the genus Vibrio are ubiquitous in aquatic environments. They adopt free and associated lifestyles. They establish mutualistic, commensal and parasitic symbioses with numerous metazoa. In the healthy Crassostrea gigas oyster, an abundant and diverse microbiota that includes many Vibrio is maintained under immune homeostasis. However, under the influence of biotic or abiotic stressors a dysbiosis is created favoring the proliferation of opportunistic Vibrio species, which can induce the death of oysters. This occurs during the Pacific Oyster Mortality Syndrome (POMS), which is caused by an immunosuppressive virus, OsHV-1 µvar. We have here characterized the Vibrio / C. gigas interactions in health and disease. We show that in populations of V. splendidus associated with healthy oysters, virulence and colonization capacity can be constrained by the selection of O-antigen structures that are more easily recognized by the host immune system but which confer resistance to grazing by marine amoebae. This trade-off between the ability to colonize its host and environmental persistence is likely the cause of the great structural diversity observed for the O-antigen in this species. In a pathological context, we have shown that the species associated with the oyster are for the most part cytotoxic for the immune cells of their host, regardless of the environment considered (Atlantic, Mediterranean). This cytotoxicity is a key determinant of the escape from the oyster's powerful cellular defenses and determines the infectious success. We observed that the molecular bases of cytotoxicity are specific to each Vibrio species studied. Finally, beyond opportunistic pathogens that use cytotoxicity (V. tasmaniensis, V. crassostreae, V. splendidus, V. harveyi), we have identified simple opportunists, such as V. rotiferianus, which not only benefit from the immunosuppressive activity of other pathogens but also adopt strategies of non-cooperative acquisition of public goods, such as siderophores produced by the microbial community hosted by their host

Abstract:
The discovery of the non-coding RNA (ncRNA) has been primarily focused on the genomes of eukaryotes and pathogenic bacteria. In vibrios, all that is known up to now regarding ncRNAs involves V. cholerae N16961 e V. campbellii ATCC BAA-1116. In this study, ncRNA candidate genes were identified in the genomes of V. campbellii ATCC BAA-1116, V. alginolyticus 40B, V. communis 1DA3 e V. mimicus VM573. V. alginolyticus 40B and V. campbellii ATCC BAA-1116 are abundant in brazilian corals, whereas V. mimicus VM573 is a toxic strain (carrying the Vibrio pathogenicity island) atypical to this species. In order to identify the ncRNAs in silico, the tools Infernal and Rfam database were used. Perl programs were developed in the present work. The Infernal tool and the Rfam database are based on the Covariance Model (CM), a special case of Stochastic Context Free Grammars (SCFG). Up to 38 ncRNAs were identified per species. They were classified into seven classes according to their regulatory function and/or structural (1. riboswitches, 2. modulators of protein activity, 3. RNA's antisensus of trans action, 4. RNA's antisensus of cis action, 5. ribonucleoproteins, 6. regulation by transcription termination and 7. unknown classification). The most abundant group was the riboswitch, whereas the less abundant group was the ribonucleoprotein. This work demonstrated that the ncRNAs show a great diversity in functional classes, possibly associated with the regulation of different cellular processes in vibrios, including regulation of pathogenicity.

Em vibrios, o que se conhece até o momento sobre ncRNAs envolve V. cholerae N16961 e V. campbellii ATCC BAA-1116. Neste estudo, são identificados genes candidatos de ncRNAs no genoma de V. campbellii ATCC BAA-1116, V. alginolyticus 40B, V. communis 1DA3 e V. mimicus VM573. V. alginolyticus 40B e V. campbellii ATCC BAA-1116 são abundantes em corais brasileiros, enquanto que V. mimicus VM573 é uma linhagem toxigênica (CT e TCP positiva) atípica desta espécie. Para identificar os ncRNAs através de análise in silico foram utilizadas ferramentas já disponíveis (Infernal e a base de dados Rfam) e programas em Perl desenvolvidos no presente trabalho. A ferramenta Infernal e a base de dados Rfam são baseados em modelo de covariância (CM), um caso especial de gramáticas estocásticas livres de contexto (SCFG). Foram identificados até 38 ncRNAs por espécie, os quais foram classificados em sete classes de acordo com sua função regulatória e /ou estrutural (riboswitches, moduladores da atividade de proteínas, RNAs antisenso de ação trans, RNAs antisenso de ação cis, ribonucleoproteinas, regulação por término de transcrição e classificação desconhecida). O grupo mais abundante foi o riboswitch, enquanto que o grupo menos abundante foi o ribonucleoproteina. Este trabalho demonstrou que os ncRNAs apresentam uma ampla diversidade de classes funcionais, estando possivelmente associados com a regulação de diferentes processos celulares em vibrio, incluindo a regulação da patogenicidade.

Abstract:
Neste estudo, 26 amostras de ostras (Crassostrea gigas) comercializadas na cidade de São Paulo e em alguns pontos do litoral de São Paulo, e 36 amostras de mexilhões (Perna perna) colhidas mensalmente em 3 pontos do litoral de Ubatuba - SP, foram submetidas à pesquisa de vibrios potencialmente patogênicos. As amostras desses moluscos eram submetidas a enriquecimento em água peptonada alcalina sem cloreto de sódio e com 1 por cento de cloreto de sódio, e GSTB. O isolamento foi realizado em ágar TCBS. Colônias sacarose positivas e negativas, sugestivas de espécies de Vibrio foram identificadas presuntivamente em meio de ágar ferro de Kligler, sendo confirmadas através de provas bioqufmicas complementares. Uma parte das amostras de vibrios potencialmente patogênicos isoladas foi submetida ao teste de Dean e teste de alça ligada em íleo de coelhos. Os vibrios potencialmente patogênicos encontrados em amostras de ostras foram V. alginolyticus (81 por cento ), V.parahaemolyticus (77 por cento ), V. cholerae não 0:1 (31 por cento ), V. fluvialis (27 por cento ), V. furnissii (19 por cento ), V. mimicus (12 por cento ) e V. vulnificus (12 por cento ) e em amostras de mexilhões foram V. alginolyticus(97 por cento ), V. parahaemolyticus(75 por cento ), V. fluvialis (47 por cento ), V. vulnificus (11 por cento ), V. cholerae não 0:1 (6 por cento ), V. furnissii (6 por cento ) e V. mimicus (6 por cento ). Observou-se acúmulo de fluido em alça ligada de íleo de coelho entre 0,25 e 0,49 ml/cm em 6,9 por cento das amostras, entre 0,5 e 0,99 ml/cm em 15,6 por cento e maior ou igual a 1 ml/cm em 15,1 por cento , e/ou intestino de camundongos lactentes (Teste de Dean) em 26,6 por cento das amostras testadas, confirmando o elevado potencial desses microrganismos em causar gastrenterite. Verificou-se ausência de variação sazonal e também, de correlação entre os vibrios potencialmente patogênicos isolados e os indicadores de contaminação fecal, confirmando que a presença desses microrganismos ocorre de forma autóctone e que, as condições climáticas foram favoráveis à sobrevivência dessas espécies em todas as épocas do ano. Considerando-se os resultados obtidos no presente estudo e o fato de que ostras e mexilhões são habitualmente ingeridos crus ou insuficientemente cozidos, pode-se concluir que sua ingestão constitui-se em um determinado grau de risco para a saúde do consumidor.
In this work, 26 oysters samples (Crassostrea gigas), found in the market of São Paulo city and some coastal areas of São Paulo State, and 36 mussels samples (Perna perna), that were collected monthly in 3 coastal areas of Ubatuba city - SP., were analyzed for the potential patogenic vibrios occurrence. Samples were enriched in alcalin peptone water with (1 per cent ) and without sodium cloride and GSTB. Isolation was performed on TCBS agar. suspect sacharosis positive and negative colonies, resembling vibrio species, were presumptively identified on Kligler iron agar, and confirmed by complementary biochemical tests. Some of this potential patogenic vibrios were submitted to suckling mouse assay and rabbit ileal loop assay. Potential patogenic vibrios isolated from oyster samples were: V. alginolyticus (81 per cent ), V. parahaemolyticus (77 per cent ), V. cholerae non 0:1 (31 per cent ), V. fluvialis (27 per cent ) I V. furnissii (19 per cent ), V. mimicus (12 per cent ) and V. vulnificus (12 per cent ) and from mussels samples were: V. a.1ginolyticus (97 per cent ), V. parabaemolyticus (75 per cent ), V. fluvialis (47 per cent ), V. vulnificus (11 per cent ), V. cholerae non 0:1 (6 per cent ), V. furnissii (6 per cent ) and V. mimicus (6 per cent ). It was found 6,9 per cent of samples between 0,25 and 0,49 ml/cm of fluid accumulation in ileal loop assay, 15,6 per cent between 0,5 and 0,99 ml/cm and 15,1 per cent was equal or higher than 1 ml/cm. Among the samples assayed for suckling mouse 26,6 per cent were positive. These results confirm the high potential of these microrganisms to induce gastroenteritis. Seasonal variation as well as correlation between the potential patogenic vibrios isolated and the fecal contamination indicators were not found, confirming that the presence of such microrganisms occurs autochthonously and that the climate conditions were favourable to these species survival during the whole year. with the results of this work and considering that oyster and mussels are usually ingested raw or insufficiently cooked, the conclusion is that the ingestion of such mollusks presents a certain degree of risk for the consumer\'s health.

Abstract:
Monoclonal antibodies were developed against pathogenic vibrios for use in rapid identification in disease situations of humans, fish and shellfish. Of the 12 fusions performed using V. alginolyticus, V. anguillarum, V. carchariae, V. cholerae, V. damsela, V. furnissii, V. harveyi, V. ordalii, V. parahaemolyticus and V. vulnificus, a total of 102 hybridomas were obtained. Based on cross-reactivity of a wide range of Vibrio strains and other gram-negative bacteria, three broad types of monoclonal antibodies were found. The three categories were: (1) ones that were species-specific or specific to a particular surface antigen, (2) a large number that reacted with several Vibrio species, and (3) three that reacted with most Vibrio strains but no other gram-negative bacteria. Each species-specific monoclonal antibody only recognized its corresponding Vibrio species and was used for identifying unknown species, confirming diagnosis of clinical isolates. In addition, several monoclonal antibodies only cross-reacted with similar Vibrio species, e.g. V. parahaemolyticus and V. alginolyticus which share a common H-antigen. Monoclonal antibodies reacting with several Vibrio species were not of particular use in diagnostic situations. Three monoclonal antibodies of the last group did not react with other genera of the family Vibrionaceae, namely Aeromonas, Photobacterium and Plesiomonas nor a wide range of gram-negative enteric bacteria. These data indicated the existence of an antigenic surface determinant common to Vibrio species. One monoclonal reacted with the heat-stable antigenic determinants on the cell surface as v as lipopolysaccharide extracted from all the vibrios studied, thus making it useful for large- scale screening of acute infections of vibrios. In a blind test, seven Vibrio species, isolated from 6 marine and a freshwater source were identified by two laboratories using phenetic tests. Results of immunotyping using monoclonals, three of seven were diagnosed as the same species, another three were designated as Vibrio species but could not be classified further due to the library not having the corresponding monoclonal, and one was diagnostically questionable. Two further tests were carried out. An unknown Vibrio formalin-fixed isolated from diseased marine animal was identified as V. parahaemolyticus by ELISA and FITC. Clinical human isolates of V. alginolyticus, V. parahaemolyticus and V. vulnificus were confirmed by monoclonals. Australian isolates of V. anguillarum appeared to be mostly of serotype O1. monoclonals raised to V. anguillarum AFHRL 1 reacted with only serotype O1 from Denmark but also most Australian isolates. All vibrios pathogenic to fish and shellfish, i.e. V. anguillarum, V. ordalii, V. alginolyticus, V. carchariae, V. cholerae, V. damsela, V. harveyi, V. parahaemolyticus and V. vulnificus, were used for attachment studies to fish cells using phase contrast and FITC-immunofluorescence microscopy. Of these vibrios, V. anguillarum, V. ordalii and V. perahaemolyticus, were found to adhere to different cells and tissues of rainbow trout while others did not appear to attach. However, attachment was inhibited by monoclonal antibodies specific to only these three vibrios. Lipopolysaccharide is well known as being a contributing factor in pathogenicity of gram-negative bacteria. PAGE electrophoresis of extracted LPS from 9 strains covering 6 Vibrio species showed the presence of a common 15,000 D fragment. This fragment was verified by immunoblotting with a genus-specific monoclonal antibody (i.e. F11P411F) recognizing nearly all vibrios. The common LPS fragment was separated and used to raise polyclonal antisera in mouse which reacted strongly with LPS itself, live as well as sodium azide-killed vibrios, but not with other gram-negative bacteria. This raised the possibility of developing vaccine from Vibrio LPS. Monoclonal antibodies developed in the present study enabled rapid identification of a number of pathogenic Vibrio species. There is still further work to produce monoclonal antibodies against additional vibrios that are probably pathogenic. These included V. fluvialis, V. hollisae, V. metschnikovii, V. minicus, V. salmonella and V. tubiashii. Together the application will be of significance in clinical diagnostic work, in the monitoring of vibriosis in fish farms and in quarantine.

Abstract:
The paper presents the results of studies of the parasitological, infectious and biochemical status of the giant oyster (Crassostrea gigas) from the Black Sea mariculture farms. The studies were carried out in May and August 2020. The occurrence of pathogens of clionosis, polydorosis, hexamitosis in oysters grown in the Black Sea was revealed. Vibrios Vibrio pomeroyi, V. gigantis, V. pacinii, V. harveyi, V. alginolyticus, V. fortis were isolated among the causative agents of infectious diseases of molluscs, of which Vibrio pomeroyi, V. alginolyticus were recognized as pathogenic for Crassostrea gigas. The reference ranges of indicators of enzymes of the antioxidant complex were determined. The obtained data allow planning both preventive and therapeutic measures on oyster farms.

Abstract:
Vibrational energy transfer in condensed phases is a process which occurs on the picosecond time scale. In our lab, we are studying this process in complex molecules in the well-defined environment of a single molecular crystal. We have measured the lifetime of several vibrons in the model system naphthalene, and then extended these studies to several partially deuterated naphthalenes [1,2]. Vibrations in pure crystals form delocalized vibron bands which relax by emission of optical phonons. In disordered or mixed crystals, excited vibrations scatter off impurities and transfer energy to adjacent molecules. Our mixed crystal studies identified these processes. An important question which was raised was the relative importance of two types of relaxation processes. In a one site process, an excited vibration on one molecule decays to a lower vibration in the same molecule by emitting a phonon. In a two site process, the excited vibration decays to a mode on an adjacent molecule. In the naphthalene system, both processes seem to be important.
