Resumo
Avaliaram-se 200 unidades de mexilhões (Perna perna) cultivados em sistemas longline na Baía de Ilha Grande, a fim de avaliar a presença de Vibrio spp. As amostras foram analisadas e submetidas a enriquecimento em água peptonada alcalina adicionada de 1% de NaCl, incubadas a 37ºC por 24 horas. Em seguida, os cultivos foram semeados em Agar tiossulfato citrato bile sacarose e as colônias suspeitas foram submetidas à caracterização bioquímica. Vibrio alginolyticus, V. harveyi e V. cincinnatiensis representaram as principais espécies (>70%) isoladas dos mexilhões in natura.(AU)
Two hundred mussels (Perna perna) samples cultivated in longline system at Ilha Grande Bay, were evaluated in order to investigate the presence of Vibrio spp. The samples were analyzed and subjected to enrichment in alkaline peptone water with the addition of 1% NaCI and incubated at 37°C for 24 hours. Following this, the cultures were seeded onto thiosulfate citrate bile sucrose agar (TCBS) and the suspected colonies were subjected to biochemical characterization. Vibrio alginolyticus, V. harveyi and V. cincinnaiiensis were the main species (>70%) isolated from raw mussels. (AU)
