Avaliou-se a incidência de Vibrio spp. a partir de lesões superficiais em mamíferos marinhos encalhados ou capturados em redes de pesca nas regiões litorâneas do Sudeste (Rio de Janeiro) e Sul (RS) do Brasil. Foram coletadas 198 amostras, pelas instituições de pesquisa DEENSP, GEMARS e Ceclimar, as quais foram enviadas ao Labent/IOC/FIOCruz, onde foram submetidas ao enriquecimento em Água Peptonada Alcalina (APA) adicionada de 1% e 3% de NaCl e in-cubadas a 37ºC por 18-24 horas. Em seqüência foram semeadas em meio Agar Tiossulfato Citrato Bile Sacarose (TCBS) e as colônias suspeitas submetidas à caracterização bioquímica. Foram isoladas 108 cepas bacterianas, destacando-se Vibrio alginolyticus, V. parahaemolyticus, V. vulnificus e V. fluvialis como os principais patógenos isolados. Os resultados obtidos apontam para a necessidade de implementar atividades de vigilância e monitorização bacteriológica, particularmente de espécies selvagens, e reforçar os programas de proteção ambiental em casos de mamíferos marinhos ameaçados de extinção. In the present investigation was evaluated the incidence of Vibrio spp. from superficial lesions at marine mammals beached or captured by fishing net in the southwestern (RJ) and southern (RS) coastal regions of Brazil. One hundred and ninety eight swabs were collected by DEENSP, GEMARS and Ceclimar institutes and sent to Labent/IOC/FIOCruz where the samples were submitted to enrichment in Alkaline Peptone Water (APW) added with 1% and 3% of sodium chloride (NaCl) incubated at 37ºC for 18-24 hours. After the samples were streaked onto Thiossulfate Citrate Bile Sucrose Agar (TCBS), the suspected colonies were submitted to biochemical characterization. The results showed 108 strains, and Vibrio alginolyticus, V. parahaemolyticus, V. vulnificus and V. fluvialis were the main pathogens isolated. These results appoint the importance of surveillance and microbiological monitoring accomplishment and reinforcement of environmental protective programs applied to marine mammals endangered with extinction
