Abstract
BackgroundExtraintestinal 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.FindingsExPEC 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.DiscussionThe findings suggest that dogs may be an important source of antibiotic resistant ExPEC.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-015-1103-2) contains supplementary material, which is available to authorized users.
Highlights
Extraintestinal pathogenic E. coli (ExPEC) are common causative agents of urinary tract infections in humans
E. coli from the shoes of dog park visitors displayed a higher level of resistance to all antibiotic classes in comparison to isolates collected from control shoe swabs
Tetracycline resistance was common among E. coli isolates from dog stools (13%) and the shoes from dog park visitors (17%)
Summary
Extraintestinal pathogenic E. coli (ExPEC) are common causative agents of urinary tract infections in humans. E. coli isolates positive for two or more of the six hallmark virulence genes were classified as ExPEC (see Additional file 1). Findings A total of 16 dog stool specimens, 16 dog park visitor shoe swabs and 16 control shoe swabs were taken. Fourteen dog stool samples (88%) and 14 swabs from the soles of shoes of dog park visitors (88%) were positive for E. coli.
