Colonization factor antigen II-producing enterotoxigenic Escherichia coli serotypes possessed at least one large plasmid. Loss of colonization factor antigen II correlated with either complete or partial loss of the large plasmid. Complete loss of the plasmid always correlated with complete loss of enterotoxin production. Three of five deletion events also correlated with the loss of toxin production.
产生定居因子抗原II的产肠毒素大肠杆菌血清型拥有至少一个大质粒。定居因子抗原II的丧失与大质粒的完全或部分丧失相关。质粒的完全丧失总是与肠毒素产生的完全丧失相关。五个缺失事件中的三个也与毒素产生的丧失相关。
