American Crows as Carriers of Extra Intestinal Pathogenic and Avian Pathogenic-Like and Their Potential Impact on a Constructed Wetland.

The study examines whether crows are carriers of extraintestinal pathogenic (ExPEC) and avian pathogenic (APEC)-like strains, and if wetland roost areas contribute to their spread. A total of 10 crow feces ( = 71) and 15 water isolates ( = 134) from a wetland area could be characterized as potentially ExPEC based on the presence of ≥2 of the five cardinal genes and while six fecal and 14 water isolates could be characterized as potentially APEC-like based on the presence of plasmid associated genes: , episomal and . A total of 32 fecal and 27 water isolates tested carried plasmids based on incompatibility typing.
