| The relationship between production of enzymes and pathogenicity of Malassezia pachydermatis strains was studied. Thirty strains of M. pachydermatis isolated from dogs were used: 15 originating from animals with external otitis and 15 obtained from ears of asymptomatic dogs. The samples, obtained by introduction of a sterile swab into the auditory canal after cleaning the auricle with alcohol-ether solution, were seeded onto Sabouraud dextrose agar with chloramphenicol (100mg/l) and were incubated at 37°C for up to two weeks. The colonies were identified according to their macro-and-micromorphology. All strains were investigated for the production of chondroitin-sulphatase, hyaluronidase, phospholipase and proteinase. Most of the strains showed a high... |

| RESUMO A cadeia produtiva do Caiman yacare tem-se destacado no Mato Grosso com a exportação de 143.386 peles em 2015, cujo sistema de manejo (ranching) implica a incubação artificial dos ovos. Nesse processo, a contaminação bacteriana de ovos influencia a taxa de eclosão. O conhecimento da microbiota de ovos incubados naturalmente orienta o manejo sanitário adequado no incubatório. No presente estudo, são apresentadas informações sobre essa microbiota e sua correlação com a de outros crocodilianos, apontando-se as espécies com potencial patogênico. Amostras de 20 ninhos de C. yacare foram coletadas e semeadas em ágar sangue e ágar Mac Conckey. A colônia condizente com Salmonella sp. foi confirmada pela técnica de reação em cadeia de polimerase. Das 22... |

| Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is a chronic disorder that affects thousands of people around the world. These diseases are characterized by exacerbated uncontrolled intestinal inflammation that leads to poor quality of life in affected patients. Although the exact cause of IBD still remains unknown, compelling evidence suggests that the interplay among immune deregulation, environmental factors, and genetic polymorphisms contributes to the multifactorial nature of the disease. Therefore, in this review we present classical and novel findings regarding IBD etiopathogenesis. Considering the genetic causes of the diseases, alterations in about 100 genes or allelic variants, most of them in... |

| Normal fungal conjunctiva microbiota of horses remains stable in healthy animals, free from ocular and/or systemic diseases which may, eventually, cause ocular alterations. The knowledge of the fungal microbiota is of great importance due to the reduced number of studies reported in the literature and also to the large occurrence of ocular alterations, mainly keratomycosis, in these animals. The aim of this study was to isolate and to identify the fungi present in the ocular conjunctiva of healthy horses belonging to the Military Police Cavalry of Alagoas. Samples from both conjunctival sacks from 50 horses were taken using a sterile swab and submitted to fungal cultures. These samples were seeded by radial spreading of the swabs on the Sabouraud agar... |

| Both the study of Brazilian wild mammal fauna and the conditions that foster the preservation of endangered species, such as Brazilian Maned-wolf (Chrysocyon brachyurus), in wild life are of extreme importance. In order to study the resistance profile of microbiota bacterial colonizing Brazilian Maned-wolf, this work investigated samples from eight male captive and free roaming animals originating from different Brazilian geographical regions. Samples for microbiological purposes were collected with swabs and kept in appropriate transport medium. Using routine microbiological techniques, the isolated bacteria were tested toward antimicrobial drugs by the agar disk diffusion method. Results showed that all samples from wild animals were sensitive toward all... |

| Strict and facultative culturable anaerobic bacteria from the digestive tract of six American black vultures (Coragyps atratus Bechstein 1793) were isolated and identified. After capture, the birds received a non-contaminated diet for one week to eliminate possible allochthonous microorganisms. Then, specimens collected from tongue, stomach and intestines were weighed, submitted to decimal dilution in an anaerobic chamber, inoculated into culture media and incubated aerobically and anaerobically at 37ºC for enumeration, isolation and identification. Isolated bacteria were submitted to tests to detect possible antagonisms between them. The total bacterial population along the digestive tract ranged from 3.46 ± 0.39 log CFU/g in the stomach to 10.75 ± 0.37... |

| Black lion tamarins (Leontopithecus chrysopygus) are endangered callithrichids. Their conservation may require future translocations or reintroductions; however these approaches involve risks of pathogen introduction in the environment and stress-related opportunistic infections in these animals. In order to screen for opportunistic and potential pathogenic bacterial and fungal microbiota, ten free-ranging and ten captive Black lion tamarins were studied and the results compared. Nasal, oral and rectal swabs were collected and cultured for aerobic and facultative anaerobic bacteria and fungi, and a total 203 bacterial and 84 fungal isolates were obtained. Overall, the most frequent organisms were Staphylococcus spp., Bacillus spp., Candida spp. and... |

| Abstract In this study for the first-time microbial communities in the caves located in the mountain range of Hindu Kush were evaluated. The samples were analyzed using culture-independent (16S rRNA gene amplicon sequencing) and culture-dependent methods. The amplicon sequencing results revealed a broad taxonomic diversity, including 21 phyla and 20 candidate phyla. Proteobacteria were dominant in both caves, followed by Bacteroidetes, Actinobacteria, Firmicutes, Verrucomicrobia, Planctomycetes, and the archaeal phylum Euryarchaeota. Representative operational taxonomic units from Koat Maqbari Ghaar and Smasse-Rawo Ghaar were grouped into 235 and 445 different genera, respectively. Comparative analysis of the cultured bacterial isolates revealed distinct... |

| Objetivou-se com este trabalho verificar o efeito do fornecimento de um "pool" de Lactobacillus sp. de origem suína para leitões nas fases de aleitamento e de creche sobre a contagem fecal de Lactobacillus, coliformes, Clostridium e Enterococcus. Foram analisadas 81 amostras fecais coletadas aos 7, 28 e 49 dias de idade, provenientes de leitões distribuídos em um delineamento experimental de blocos casualizados com três tratamentos (A- ração controle, B- ração contendo promotor de crescimento e C- fornecimento diário de probiótico do 1º ao 49º dia de vida). O probiótico testado não foi eficiente em alterar significativamente a microbiota intestinal dos animais (P>0,10); entretanto, os animais que o receberam por 49 dias obtiveram, numericamente, maior... |

| ABSTRACT: Despite the known importance of Clostridium perfringens as an enteropathogen in small ruminants, little is known about the role of its additional virulence factors or the frequency of the various C. perfringens genotypes in healthy goats; this complicates the laboratory diagnosis of the infections caused by this microorganism. In light of this, the aim of the present study was to isolate and genotype C. perfringens from stool samples from healthy goats in Brazil. Stool samples from 250 apparently healthy adult goats from 17 different herds in Minas Gerais, Brazil were collected, and isolation and genotyping of C. perfringens was performed. C. perfringens type A was isolated from 189 (75.6%) goats, whereas C. perfringens types C and D were each... |
