For this, 20 samples of marine shrimp (Penaeus sp.) were collected from Itajuru channel, Cabo Frio, RJ, and other 20 samples of farmer shrimp were acquired in municipal market of Cabo Frio, RJ between January to August 2007. These samples were processed using standard methodology and inoculated in selective media for the research of these microorganisms. The isolates identification was performed by specific biochemical tests. 88 strains were isolated; 51.1% belonging to Vibrio sp., 28.5% to Aeromonas sp. and 20.4% to Plesiomonas shigelloides. It was not detected the presence of E. coli or Salmonella. Among the Vibrio sp., there was a prevalence of Vibrio alginolyticus with 45% and Vibrio parahaemolyticus with 10.5%. Aeromonas hydrophila contributed with 30% of the isolates of this genus and 83.3% of the isolates from Plesiomonas shigelloides were obtained from marine shrimp while 16.7% were obtained from farmer shrimp. The results show a high frequency of potentially pathogenic strains in these shrimps, emphasizing the importance of monitoring these organisms not only to shrimp industry but also to public health. / Este trabalho teve como objetivo pesquisar em camar?es de vida livre e criados em cativeiro a presen?a de microrganismos dos g?neros Vibrio, Aeromonas e representantes da fam?lia Enterobacteriaceae. Para tal, foram coletadas 20 amostras de camar?o de vida livre (Penaeus sp.) do canal de Itajuru, Cabo Frio, RJ; e outras 20 amostras de camar?o de cativeiro do com?rcio local deste munic?pio, no per?odo de Janeiro a Agosto de 2007. Estas amostras foram processadas seguindo metodologia padr?o e inoculadas em meios seletivos para a pesquisa dos microrganismos citados. A identifica??o dos isolados foi realizada atrav?s de testes bioqu?micos espec?ficos. 88 cepas foram isoladas, das quais, 51,1% pertencente ao g?nero Vibrio, 28,5% ao g?nero Aeromonas e 20,4% a Plesiomonas shigelloides. Em nenhuma amostra foi detectada a presen?a de E. coli ou Salmonella spp. Dentre os Vibrios, houve predomin?ncia de Vibrio alginolyticus com 45% e Vibrio parahaemolyticus com 10,5%. Aeromonas hydrophila contribuiu com 30% dos isolados deste g?nero e 83,3% dos isolados de Plesiomonas shigelloides foram obtidos de camar?o de vida livre enquanto 16,7% foram obtidos de camar?o de cativeiro. Os resultados apresentam uma grande freq??ncia de cepas potencialmente patog?nicas ao homem presentes nestes camar?es; ressaltando a import?ncia do monitoramento destes organismos n?o s? para a ind?stria de carcinicultura como tamb?m para a sa?de p?blica.
