Choleriform Syndrome and Production of Labile Enterotoxin (CT/LT1)-like Antigen by Species of Salmonella infantis and Salmonella haardt Isolated from the Same Patient

Salmonella species produce a series of toxins [1] including a cytotoxin and an enterotoxin with as-yet-undetermined significance for human disease. The Salmonella CT/LT-like enterotoxin appears to be similar to the heat-labile enterotoxin from several other enteric bacilli [2]. It affects transport of fluid in the small intestine by stimulating the adenylate cyclase system [2]. We report here the production of CT/LT1like enterotoxin antigen in two different Salmonella species isolated from a patient with choleriform diarrhea.
