Colonization factors associated with enterotoxigenic Escherichia coli isolated in Thailand

Abstract

Eighty-six percent (72 of 84) of heat-labile and heat-stable, none of 141 heat-labile, and 24% (27 of 111) heat-stable enterotoxigenic Escherichia coli isolates from Thailand aggregated in less than 1 M (NH4)2SO4, hemagglutinated human group A and bovine erythrocytes in 1% D-mannose, and possessed either colonization factor I or colonization factor II. No other colonization factors were identified by these two methods.
