About 17% (198 of 1,131) fecal specimens collected from July 1986 through August 1987 contained the organism. Both O1 and non-O1 V. cholerae strains were isolated from the fecal specimens. Isolates from eight birds (representing five species) agglutinated in O group 1 antiserum. Supernatants of broth cultures from three isolates which typed as V. cholerae O1 serotype Ogawa gave reactions typical of cholera toxin when tested on Y-1 mouse adrenal cell cultures. Several serovars of non-O1 V. cholerae were isolated from the fecal specimens; serovar 22 was the most prevalent type. All non-O1 isolates were cyctotoxic to Y-1 mouse adrenal cells. Only non-O1 V. cholerae was detected in water samples collected from the habitat of the birds. The results of this study suggest that aquatic birds serve as carriers and disseminate V. cholerae over a wide area.Vibrio choleraeaquatic birdsArticle
