causes severe foodborne illness and is the only human pathogen in the genus . Previous surveys of AMR in focused on clinical sources and food or food processing environments, with AMR in strains from wildlife and other natural ecosystems remaining under-explored. We analyzed 185 sequenced strains from wild black bears () from the United States, including 158 and 27 . and , respectively. Tetracycline resistance was the most prevalent resistance trait. In . monocytogenes, it was encountered exclusively in serotype 4b strains with the novel Tn-like element Tn. In contrast, three distinct, novel tetracycline resistance elements (Tn, , and Tn) were identified in . Interestingly, was identical to elements in from a major foodborne outbreak in the United States in 2011. The findings suggest the importance of wildlife and non-pathogenic species as reservoir for resistance elements in .
