Previous issue date: 2008-12-01 / The aim of this study was to evaluate the presence of Vibrio sp., Aeromonas sp. and
Enterobacteriaceae in marine and farmer shrimp. 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.
