Abstract:  The aim of this study was to determine the potential of E. coli, isolated from retail meats, to cause urinary tract disease. Two hundred E. coli isolates from retail meats were analyzed for the presence of 21 uropathogenic E. coli (UPEC) virulence-associated genes. Twenty-three E. coli isolates were analyzed further using multilocus sequence typing (MLST) and tissue culture assays. Of the 23 selected isolates, 17 belonged to sequence types associated with human UPEC. Nearly all the isolates exhibited a lower level of adherence and invasion compared to a strain from a UPEC-infected human patient. The results suggested a small proportion of E. coli isolates from retail meats resembled human UPEC. The potential for these isolates to cause human urinary tract infections needs more investigation.
