Antibiotic resistant bacteria in migratory birds: evidence for factors driving emergence and the potential for redistribution by wild birds

Antibiotic resistant bacteria have recently been detected in remote northern Alaska near Barrow, suggesting that these evolved bacterial strains are potentially widely distributed amongst avian populations and in proximity to human settlements. The USGS is collaborating with colleagues who initially detected these resistant strains in Alaska to develop a broader perspective on antibiotic resistant bacteria across Alaska.

Abstract


Antibiotic-resistant bacteria pose challenges to healthcare delivery systems globally; however, limited information is available regarding the prevalence and spread of such bacteria in the environment. The aim of this project was to compare the prevalence of antibiotic resistant bacteria in large-bodied gulls (Larus spp.) at urban and remote locations in southcentral Alaska to gain inference into the association between antibiotic resistance in wildlife and anthropogenically influenced habitats.
