Infection with non-typhoidal Salmonellae usually causes a self-limiting dysenteric illness. Several factors are known to increase the propensity to invasive disease — With its related sequelae. We present four previously healthy patients who had none of the recognised risk factors but developed Salmonella infection with a severe and protracted illness. Common to each of these patients was the pre-hospital oral administration of anti-diarrhoeal drugs.
