Escherichia coli O157 Cluster Evaluation

摘要

We investigated a multistate cluster of Escherichia coliO157:H7 isolates; pulsed-field gel electrophoresis subtyp-ing, using a single enzyme, suggested an epidemiologicassociation. An investigation and additional subtyping,however, did not support the association. Confirming E. coliO157 clusters with two or more restriction endonucleasesis necessary before public health resources are allocated tofollow-up investigations
