Abstract:
A probe specific for the uidA gene of Escherichia coli hybridized with 112 of 116 E. coli isolates examined, including 31 beta-D-glucuronidase-negative and 12 enterohemorrhagic E. coli serotype O157:H7 isolates. Southern hybridizations confirmed the presence of a 900-bp HinfI fragment from the uidA gene in all isolates examined, suggesting that uidA gene sequences are present in most E. coli.
