Carbapenemase-Producing Gram-Negative Bacteria From American Crows In The United States

Wild corvids were examined for the presence of carbapenemaseproducing Gram-negative bacteria in the United States. A total of 13 isolates were detected among 590 fecal samples of American crow; 11 Providencia rettgeri isolates harboring bla(IMP-27) on the chromosome as a class 2 integron gene cassette within the Tn7 transposon, 1 Klebsiella pneumoniae ST258 isolate carrying bla(KPC-2) on a pKpQIL-like plasmid as a part of Tn4401a, and 1 Enterobacter bugandensis isolate with bla(IMI-1) located within EcloIMEX-2.
