An outbreak of severe diarrheal illness was recently reported in northeastern Oklahoma, and Shiga toxin-producing Escherichia coli serotype O111 was identified as the etiological agent. Our results indicated that this isolate is unable to decarboxylate lysine, a characteristic that is shared with other outbreak-linked O111 isolates. Therefore, further investigation is recommended to determine whether the lysine decarboxylase test could be used to identify a subset of pathogenic E. coli, particularly Shiga toxin-producing E. coli O111 isolates, that have the potential of causing human infections and outbreaks.
近期，俄克拉荷马州东北部报告了一起严重腹泻病疫情，志贺毒素产生型大肠杆菌血清型 O111 被鉴定为病原体。我们的研究结果表明，该分离株不能脱羧赖氨酸，这一特征与其他疫情相关的 O111 分离株相同。因此，建议进一步调查，以确定赖氨酸脱羧酶试验是否可用于鉴定一组具有引起人类感染和疫情潜力的特定致病性大肠杆菌，特别是产志贺毒素大肠杆菌 O111 分离株。
