De 3.250 fezes diarréicas, recebidas para diagnóstico microbiológico em laboratório clínico particular, no Recife, Brasil, isolaram-se 55 (1,7%) linhagens de Vibrio. O estudo foi realizado entre maio de 1989 e maio de 1991. Para o isolamento de Vibrio, os espécimes fecais foram enriquecidos em água peptonada alcalina suplementada com 2% de NaCl e subcultivados em ágar tiosulfato-citrato-sais biliares-sacarose (TCBS). Das espécies isoladas, V. parahaemolyticus foi a mais freqüente (24 cepas), seguida de V. furnissii (15 cepas), V. cholerae não 01 (6 cepas), V. alginolyticus (4 cepas), V. fluvialis (2 cepas) e Vibrio sp. (1 cepa). Do ponto de vista custo-benefício, a baixa taxa de isolamento de Vibrio levanta dúvidas acerca da utilidade do TCBS na rotina enterobacteriológica dos laboratórios clínicos Of 3250 diarrheal stools received for microbiologic diagnosis at a private clinical laboratory in Recife, Brazil, strains of Vibrio were isolated from 55 (1.7%). The study was carried out from May 1989 through May 1991. For recovering Vibrio, fecal samples were enriched in alkaline peptone water supplemented with 2% NaCl and subcultured on thiosulfate-citrate-bile salts-sucrose agar (TCBS). Of the recovered species, V. parahaemolyticus was most commonly found (24 strains), followed by V. furnissii (15 strains), V. cholerae non-01 (6 strains), V. alginolyticus (4 strains), V. fluvialis (2 strains), and Vibrio sp. (1 strain). The low isolation rate of Vibrio raises doubts about the cost-effectiveness of the use of TCBS in the routine enterobacteriologic workup of clinical laboratories
