Description
Summary:The objective of the study described in this article was to characterize the antimicrobial resistance profiles amongE. colistrains isolated from cohabitant pets and humans, evaluating the concurrent colonization of pets, owners, and home surfaces by bacteria carrying the same antimicrobial-resistant genes. The authors also intended to assess whether household surfaces and objects could contribute to the withinhousehold antimicrobial-resistant gene diffusion between human and animal cohabitants. A total of 124E. colistrains were isolated displaying 24 different phenotypic patterns with a remarkable percentage of multiresistant ones. The same resistance patterns were isolated from the dog’s urine, mouth, the laundry floor, the refrigerator door, and the dog’s food bowl. Some other multiresistant phenotypes, as long as resistant genes, were found repeatedly in different inhabitants and surfaces of the house. Direct, close contact between all the cohabitants and the touch of contaminated household surfaces and objects could be an explanation for these observations.
