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.
