RESUMO

Nine strains of Escherichia coli serogroup O149 isolated from diarrheic calves were found to produce a heat-labile enterotoxin. The heat-labile enterotoxin activity was destroyed by heat (85 degrees C/30 min) and was neutralized by rabbit anti-heat-labile enterotoxin. One of the strains also produced a heat-stable enterotoxin.
