| Oysters are filter feeders able to ingest particles in suspension that may carry pathogenic microorganisms. In this respect, the consumption of raw oysters can cause foodborne diseases in humans. The aim of the present study was to evaluate the microbiological quality of Crassostrea gigas oysters cultivated and commercialized in the coastal region of Florianópolis, SC, Brazil. The study comprised counts of coliforms at 35ºC and at 45ºC, Escherichia coli and coagulase-positive staphylococci, and detection of Salmonella sp, Vibrio cholerae and Vibrio parahaemolyticus. Ninety samples were analyzed, 45 of them collected at seafood commercial establishments and the other 45 were collected in the cultivation area. All analyses were performed according to methods... |

| The possible sources of Campylobacter spp. in poultry meat before slaughter were studied by examining samples of feathers, cloaca swabs, litter swabs, transport coops, rinse water from coop washing equipment, and chicken breast supports in the slaughter line just before stunning. The samples were collected from 8 broiler houses and from 8 different producers, from a poultry integration system in southern Brazil. The study was carried out over a 12-month period, and each broiler house was sampled in three consecutive flocks, for a total of 24 flocks/broiler house. Campylobacter was found in 79.2% of the feather samples, followed by cloacal swabs (75.0%) and transport coop (50.0%), litter (37.5%), breast support (33.3%) and coop rinse water (25.0%) samples.... |

| O objetivo deste trabalho foi isolar o agente causador da doença-da-perna-vermelha em girinos de Rana catesbeiana em fase de transformação. Coletaram-se 20 girinos, na fase G4, apresentando prostração, anorexia, pele ressecada, pernas posteriores hemorrágicas e natação errática. Amostras do coração, fígado e partes da perna foram inoculadas em meio de cultura ágar triptona de soja e ágar sangue, a 25°C, por 48 horas. Aeromonas hydrophila foi a principal causa do surto de mortalidade. A fim de avaliar o efeito dessa bactéria nos girinos, realizou-se inoculação por via oral e intraperitoneal de 10(6) unidades formadoras de colônia por mililitro, e verificou-se o aparecimento de petéquias hemorrágicas na boca e nos órgãos internos. |
