Enterotoxigenic Escherichia coli (ETEC) causes childhood diarrhea in developing countries. ETEC strains produce the heat-labile enterotoxin (LT) and/or heat-stable enterotoxins (ST) and encode a diverse set of colonization factors used for adherence to intestinal epithelial cells. We previously found that ETEC secretes a heat-stable protein we designated as ETEC Secreted Factor (ESF) that inhib...
Twenty-eight clinical isolates of Yersinia enterocolitica were investigated for their abilities to produce heat-stable enterotoxin (YST). All 21 invasive strains (serogroup O3 biotype 4) carried the previously described gene for YST (yst), with toxin detectable in culture supernatants from 20 strains. One of seven noninvasive, biotype 1A strains also had enterotoxic activity, despite failure to...
An 83-year-old male presented with chronic diarrhea and protein malnutrition associated with Plesiomonas shigelloides overgrowth in the small intestine. This overgrowth was related to achlorhydria and small-bowel diverticula. Tests for heat-labile and heat-stable enterotoxin were negative on the P. shigelloides isolated from both the small bowel aspirate (3 x 10(8) bacteria per ml) and the pati...
