As plantas de cobertura de solo usadas para suprimir o crescimento de plantas daninhas podem hospedar fungos fitopatogênicos. Para testar essa hipótese, elaborou-se este trabalho com o objetivo de avaliar o comportamento de nove espécies de plantas como possíveis hospedeiras do fungo Colletotrichum guaranicola. O experimento foi conduzido em casa de vegetação sob delineamento inteiramente casualizado, com quatro repetições. Cada vaso com três plantas da mesma espécie representou uma unidade experimental. As espécies que constituíram os tratamentos foram: Arachis pintoi, Calopogonium mucunoides, Chamaecrista rotundifolia, Crotalaria striata, Desmodium ovalifolium, Flemingia congesta, Mucuna aterrima, Pueraria phaseoloides e Tephrosia candida. Quarenta dias após a semeadura, as plantas foram inoculadas com suspensão de esporos de C. guaranicola na concentração de 10(5) conídios mL¹, enquanto as plantas testemunhas receberam somente água. As plantas foram mantidas em câmara úmida por 48 horas. Diariamente, foram feitas observações por 15 dias após a inoculação, para visualizar sintomas da doença. As espécies que não apresentaram sintomas de C. guaranicola foram Arachis pintoi, Chamaecrista rotundifolia, Desmodium ovalifolium, Flemingia congesta e Tephrosia candida, e as que manifestaram sintomas após a inoculação foram Calopogonium mucunoides, Crotalaria striata, Mucuna aterrima e Pueraria phaseoloides, que podem ser fontes de inóculo do patógeno da antracnose para o guaranazeiro.

Soil carbon is one of the most affected variables to land-use change in tropics. The soil carbon flux plays a major role in regulating microbial activities and nutrient distribution in soil. This study aimed to evaluate the soil carbon stock in various land uses at different depths in the hilly terrain of Mizoram, Northeast India. Soil samples at 0-10 cm, 10-20 cm and 20-30 cm soil depths were collected from Rubber plantation (RP), Oil palm plantation (OPP), Teak plantation (TP), Bamboo Forest (BF), 5 years fallow (5YF), 10 years fallow (10YF), Tephrosia candida plantation (TCP), Horticulture garden (HORT), Homegarden (HG) and Natural forest (NF). Soil carbon stock varied significantly (p <0.05) across the land uses and depths. The soil under Tephrosia candida stand had significantly (p <0.05) higher values of C stock (73.66 Mg ha-1) which may be due to high biomass, dense vegetative cover and high C in root exudates. The minimum C stock estimated in Horticulture garden (43.28 Mg ha-1) is probably due to reduced soil organic matter. Soil carbon stock in Homegarden, Teak plantation, Bamboo forest and Rubber plantation ranged from 46.82 Mg ha-1 to 59.34 Mg ha-1 whereas 5 years and 10 years fallow land, Natural forest and Oil palm plantation ranged from 61.35 Mg ha-1 to 73.35 Mg ha-1. The study indicated that the land use change in the mountainous region significantly affected the carbon stock in the soil. A proper land use management strategies to increase the soil organic matter is recommended to enhance the carbon stock in this region.

AbstractObjectivesTo generate antifungal susceptibility patterns for Trichomonascus ciferrii (Candida ciferrii), Candida inconspicua (Torulopsis inconspicua) and Diutina rugosa species complex (Candida rugosa species complex), and to provide key parameters such as MIC50, MIC90 and tentative epidemiological cut-off values (TECOFFs).MethodsOur strain set included isolates of clinical origin: C. inconspicua (n = 168), D. rugosa species complex (n = 90) [Candida pararugosa (n = 60), D. rugosa (n = 26) and Candida mesorugosa (n = 4)], Pichia norvegensis (Candida norvegensis) (n = 15) and T. ciferrii (n = 8). Identification was performed by MALDI-TOF MS or internal transcribed spacer sequencing. Antifungal susceptibility patterns were generated for azoles, echinocandins and amphotericin B using commercial Etest and the EUCAST broth microdilution method v7.3.1. Essential agreement (EA) was calculated for Etest and EUCAST.ResultsC. inconspicua, C. pararugosa and P. norvegensis showed elevated azole MICs (MIC50 ≥0.06 mg/L), and D. rugosa and C. pararugosa elevated echinocandin MICs (MIC50 ≥0.06 mg/L). EA between methods was generally low (<90%); EA averaged 77.45%. TECOFFs were suggested for C. inconspicua and D. rugosa species complex.ConclusionsRare yeast species tested shared high fluconazole MICs. D. rugosa species complex displayed high echinocandin MICs, while C. inconspicua and P. norvegensis were found to have high azole MICs. Overall, the agreement between EUCAST and Etest was poor and therefore MIC values generated with Etest cannot be directly compared with EUCAST results.

Annotation:

There have been increased reports of the isolation of unusual genotypic groups of Candida albicans (groups C and D) based on a well-defined genotypic method; this method uses cellular DNA digested with the EcoRI enzyme and the restriction fragment length polymorphisms (RFLPs) generated by agarose gel electrophoresis. The aim of the present study was to use additional molecular tools to characterize these unusual strains and to compare them with authentic strains of C. dubliniensis, a recently delineated species, and type I C. stellatoidea. The RFLPs of PCR products generated from the intergenic transcribed spacer (ITS) region did not differentiate among C. albicans genotypes A, B, and C and type I C. stellatoidea. However, this method did differentiate the C. albicans genotype D strains, which were identical to C. dubliniensis. The RFLPs generated by HaeIII digestion of the PCR products of the V3 region of the 25S rRNA gene (rDNA) could differentiate the same groups as RFLP analysis of the PCR amplicon of the ITS region.C. albicans genotype B isolates have been shown to have a transposable intron in the 25S rDNA, whereas genotype A isolates do not; C. dubliniensis strains also have an intron that is larger than that in genotype B C. albicansstrains but that is in the same location. PCR designed to span this region resulted in a single product for C. albicansgenotype A (450 bp), B (840 bp), type 1 C. stellatoidea (840 bp), and C. dubliniensis(1,080 bp), whereas the C. albicans genotype C isolates had two major products (450 and 840 bp). All C. albicans genotype D isolates gave a PCR product identical to that given by C. dubliniensis. These results indicate that those strains previously designated C. albicansgenotype D are in fact C. dubliniensis, that no differences were found between type 1 C. stellatoideaand C. albicans genotype B strains, and that theC. albicans genotype C strains appear to have the transposable intron incompletely inserted throughout the ribosomal repeats in their genomes. The results of the antifungal susceptibility testing of 105 of these strains showed that, for fluconazole, strains of C. dubliniensis were significantly more susceptible than strains of each of the C. albicans genotypes (genotypes A, B, and C). The flucytosine susceptibility results indicated that strains of C. albicans genotype A were significantly less susceptible than either C. albicansgenotype B or C. albicans genotype C strains. These results indicate that there is a correlation between theCandida groups and antifungal susceptibility.

In folk medicine, Vismia guianensis is used to treat skin diseases and mycoses in the Amazon region. We evaluated the anti-Candida activity of the hydroalcoholic extract from the leaves of Vismia guianensis (EHVG). HPLC-PDA and FIA-ESI-IT-MSn were used to chemically characterize EHVG. The anti-Candida activity was determined in vitro by the minimum inhibitory concentrations (MIC) against Candida glabrata (ATCC-2001); Candida albicans (ATCC-90028, ATCC-14053, and ATCC-SC5314), and C. albicans clinical isolates. EHVG effects on adhesion, growth, and biofilm formation were also determined. Molecular docking was used to predict targets for EHVG compounds. The main compounds identified included anthraquinone, vismione D, kaempferol, quercetin, and vitexin. EHVG was fungicidal against all tested strains. C. albicans ATCC 14053 and C. glabrata ATCC 2001 were the most sensitive strains, as the extract inhibited their virulence factors. In silico analysis indicated that vismione D presented the best antifungal activity, since it was the most effective in inhibiting CaCYP51, and may act as anti-inflammatory and antioxidant agent, according to the online PASS prediction. Overall, the data demonstrate that EHVG has an anti-Candida effect by inhibiting virulence factors of the fungi. This activity may be related to its vismione D content, indicating this compound may represent a new perspective for treating diseases caused by Candida sp.

Resistance to antifungal therapy of Candida albicans and non-albicans Candida strains, frequently associated with oral candidosis, is on the rise. In this context, host-defense peptides have emerged as new promising candidates to overcome antifungal resistance. Thus, the aim of this study was to assess the effectiveness against Candida species of different Catestatin-derived peptides, as well as the combined effect with serum albumin. Among Catestatin-derived peptides, the most active against sensitive and resistant strains of C. albicans, C. tropicalis and C. glabrata was the D-isomer of Cateslytin (D-bCtl) whereas the efficiency of the L-isomer (L-bCtl) significantly decreases against C. glabrata strains. Images obtained by transmission electron microscopy clearly demonstrated fungal membrane lysis and the leakage of the intracellular material induced by the L-bCtl and D-bCtl peptides. The possible synergistic effect of albumin on Catestatin-derived peptides activity was investigated too. Our finding showed that bovine serum albumin (BSA) when combined with the L- isomer of Catestatin (L-bCts) had a synergistic effect against Candida albicans especially at low concentrations of BSA; however, no synergistic effect was detected when BSA interacted with L-bCtl, suggesting the importance of the C-terminal end of L-bCts (GPGLQL) for the interaction with BSA. In this context in vitro D-bCtl, as well as the combination of BSA with L-bCts are potential candidates for the development of new antifungal drugs for the treatment of oral candidosis due to Candida and non-Candida albicans, without detrimental side effects.

Three new pimarane diterpenes, eutypellenoids A–C (1–3), together with a known compound, eutypenoid C (4), were isolated from the culture extract of Eutypella sp. D-1 derived from the Arctic region. Compounds 1–3 possessed an uncommon tetrahydrofuran-fused pimarane diterpene skeleton. The structures of all compounds were determined by detailed spectroscopic analysis, electronic circular dichroism (ECD) analysis, as well as a comparison with the literature data. Antibacterial, antifungal, and cytotoxic activities of these compounds were evaluated. Compound 2 displayed antibacterial activity against Staphylococcus aureus and Escherichia coli with MIC values of 8 and 8 μg/mL, respectively. Additionally, compound 2 showed antifungal activity against Candida parapsilosis, Candida albicans, Candida glabrata, and Candida tropicalis with MIC values of 8, 8, 16, and 32 μg/mL, respectively. Furthermore, compound 2 exhibited moderate cytotoxic activity against HCT-116 cell line with IC50 value of 3.7 μM.

Annotation:

Candida infections are frequently associated with formation of biofilms on artificial medical devices. This work studied variation of cell surface hydrophobicity (CSH) and formation of biofilm in relation to Candida albicans and Candida dubliniensis genotypes and an effect of some conventional antifungal agents on both CSH and biofilm. The 50 isolates of C. albicans and C. dubliniensis were classified into genotypes A, B, C, and D, genotype D being exclusively represented by C. dubliniensis. No significant differences between CSH of genotypes A and B and B and C were observed with respect to cultivation temperature 25 or 37 °C. Candida dubliniensis showed increased CSH in comparison with other C. albicans genotypes (p < 0.001) regardless of temperature used. Using XTT reduction assay and dry masses, genotypes B and C showed reduced ability to form biofilm in comparison with genotype A (p < 0.05) and C. dubliniensis (p < 0.001). Fluconazole reduced biofilm in C. albicans genotypes A, B, and C (p < 0.05) but not CSH. The opposite effect was observed in C. dubliniensis. Voriconazole effectively reduced both biofilm formation and CSH in all tested genotypes of C. albicans and C. dubliniensis (p < 0.05).

The present investigation includes evaluation of various solvent extracts of Costus specious (J. Koenig) Sm. and Costus pictus D. Don. for in-vitro antifungal activity against selected Candida strains. The selected plants belong to the family Costaceae. Solvents such as hexane, methanol, water, and ethyl acetate of Costus pictus and standard extract of Costus specious were evaluated against Candida albicans, Candida glabrata, Candida parapsilosis, Candida tropicalis, and Candida krusei. The susceptibility of the fungal strains against the extracts was assessed by the agar well diffusion method. Clotrimazole was used as a positive control. The zone of inhibition was determined for each extract in comparison with the positive control. Results were recorded after 72 h. Of the various extracts analyzed, the hexane extract exhibited a potential antifungal activity overall. The methanolic, ethyl acetate extract of Costus pictus and standard extract of Costus specious shows some degree of activity against C. glabrata and C. parapsilosis. The aqueous extract shows no antifungal activity against the selected fungal strains. The above study indicates that C. krusei was more resistant to the solvent extracts; however, C. albicans and C. glabrata were more susceptible. Hence, Costus specious (J. Koenig) Sm. and Costus pictus D. Don demonstrate promising antifungal potential.

Introdução: A presente pesquisa trata de destacar as principais infecções provocadas por vírus, bactérias ou fungos que causam doenças no globo ocular ou tecidos circunvizinhos podem levar a cegueira necessitando de tratamentos agressivos e muitos casos de procedimento de transplantes de córneas. Objetivo: Caracterizar infecções provocadas por microorganismos que causam patologias oculares que levam a necessidade de transplantes. Material e métodos: através de leitura criteriosa foram selecionados alguns artigos científicos na plataforma scielo que se destacaram por tratarem de afecções oftalmológicas microbianas capazes de levar a cegueira. Resultados: Verifica-se que não são poucas, nem são raras as patologias relacionadas ao globo ocular que podem levar a cegueira, seja pela impossibilidade de detecção da infecção, seja pelo tratamento necessariamente agressivo ou pela evolução da doença. Algumas doenças, organizadas por ordem alfabética são: a) Blefarite bacteriana: x; b) Ceratite Acanthamoeba: provocado por um protozoário do gênero Acanthamoeba, pode levar a úlceras da córnea e eventual perda de visão; c) Ceratite fúngica: A maioria dos casos de ceratite fúngica, em todo o mundo, é causada por fungos filamentosos septados não pigmentados. Muitos casos podem progredir para infecção fulminante e alguns pacientes perdem a sua visão por culpa do necessário tratamento agressivo; d) Ceratite herpética: Os vírus herpes simples é o vírus causador. A doença corneana decorrente dessa infecção apresenta múltiplas manifestações; e) Conjuntivites: patologias inflamatórias que afetam o tecido conjuntivo que protege o globo ocular do meio externo, observando-se dilatação vascular, infiltração celular e exsudação. As conjuntivites têm origens virais ou bacterianas; f) Endoftalmite: apresenta infecção grave intraocular, afetando humor aquoso, humor vítreo, ou ambos, e ameaça severamente a visão. A Candida albicans é o agente etiológico mais comum; g) Tracoma: infecção causada pela bactéria Chlamydia trachomatis, uma das maiores causas de cegueira infecciosa evitável do mundo. Conclusão: As patologias oftalmológicas provocadas por microorganismos, quando não devidamente tratadas, levam a perda de visão.
