ABSTRACT
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.
