Response to antimicrobial therapy for shigellosis in Thailand.

Shigella species have been one of the most common causes of acute diarrhea in Bangkok, Thailand. The incidence of shigellosis increased steadily from 1984 to 1988. The majority of Shigella species isolated from specimens from patients with acute diarrhea in Bangkok in 1988 were resistant to both ampicillin and trimethoprim-sulfamethoxazole (TMP-SMZ).
