Vibrio cholerae, Vibrio parahaemolyticus, and other vibrios: occurrence and distribution in Chesapeake Bay

Abstract

V. cholerae was isolated at several locations in Chesapeake Bay [USA] in fall 1976 and spring 1977. Strains induced fluid accumulation in rabbit ileal loops and positive activity in Y-1 adrenal [mouse] cells. V. cholerae, V. parahaemolyticus and related vibrios show a spatial and temporal distribution characteristic of Vibrio spp. in an estuary. The V. cholerae strains isolated from Chesapeake Bay represent serotypes other than O-group I, i.e., nonagglutinable vibrios, and are not recognized as a serious epidemic threat, although they have caused [human] cholera-like diarrhea sporadically.
