Background:
Extraintestinal pathogenic E. coli (ExPEC) are common causative agents of urinary tract infections in humans. Dogs have been found to harbor ExPEC. This study tested stool samples from dogs (n = 16), the shoes of dog park visitors (n = 16) and the shoes of controls (n = 16) for ExPEC. Phenotypic resistance of isolates was characterized.
Findings:
ExPEC were present in one-third of the dog stool samples, 9% of the samples from the shoes of dog park visitors and 6% of control samples. Half of the ExPEC isolates were multi-drug resistant.
Discussion:
The findings suggest that dogs may be an important source of antibiotic resistant ExPEC.
