The incidence of enterotoxigenic Escherichia coli (ETEC), Shigella, Aeromonas, and Vibrio was determined in patients with diarrhea seen at a hospital in northeastern Thailand, and compared with the incidence of these bacteria in household contacts and their neighbors. ETEC was identified in 17%, Shigella in 9%, Aeromonas in 9%, V. parahaemolyticus in 5%, and non-01 V. cholerae in 2% of 299 patients with diarrhea. These five species of bacteria were isolated more often from patients with diarrhea than persons without diarrhea (P <0.001). ETEC was found more often in household contacts (22/141) and neighbors (18/147) of index cases than in persons living in homes not associated with ETEC infections (32/1,318; P <0.001). While Shigella was isolated less often in family contacts (3/76) and neighbors (4/93) of patients with shigellosis, this enteric pathogen was also isolated more often from contacts than persons not associated with Shigella infection (13/1,437; P <0.001). Both Aeromonas and non-01 V. cholerae can also be enteric pathogens; further efforts should be made to define the enteropathogenicity of these bacteria.
