In endemic areas, biochemical confirmation and characterization of the isolate are usually unnecessary. However, these tasks may be worthwhile in areas where Vibrio cholerae is an uncommon isolate. If identification of the organism is required, direct microscopic examination of stool (including dark-field examination) is indicated, along with Gram stain, culture, and serotype and biotype identification.
