Isolation of sucrose late-fermenting and nonfermenting variants of Vibrio cholerae O139 Bengal: Implications for diagnosis of cholera

Abstract

The sucrose-containing selective medium thiosulfate-citrate-bile salt- sucrose agar missed a sucrose nonfermenting and four sucrose late-fermenting variant strains of Vibrio cholerae O139 Bengal from diarrheal stools. These strains were, however, correctly identified as V. cholerae O139 on a sucrose- deficient selective medium, taurocholate-tellurite-gelatin agar.
