RESUMO

Twenty Escherichia coli strains of serogroup O167 were examined. They all produced the two surface antigens CS5 and CS6 of the putative colonization factor PCF8775, together with heat-stable enterotoxin and colicin Ia. A plasmid coding for CS5, CS6, heat-stable enterotoxin, and colicin Ia was demonstrated in each strain.
