Abstract:
:DNA microarray analyses revealed that clusters of repetitive extragenic palindromic PCR-related Escherichia coli isolates were isogenic only within interstitial Lake Huron beach water samples and not in surrounding waters. This suggested that adaptation and growth occurred within the interstitial water sites tested. All isolates were nonpathogenic, and three lake isolates possessed tetracycline resistance genes.
