The role of gulls in Alaska in the dissemination of antimicrobial resistant E. coli

Antibiotic-resistant bacteria pose challenges to human healthcare globally; however, limited information is available regarding the prevalence and spread of such bacteria in the environment by wildlife. The aim of this project was to compare the prevalence of antibiotic resistant bacteria in migratory birds at urban and remote locations in Alaska.

Abstract


The role of gulls in Alaska in the dissemination of antimicrobial resistant E. coli project is conducted by two staff members of the Alaska Science Center (ASC) and was initiated after the finding of high bacterial levels in the Kenai River starting in 2014 by the State of Alaska. Current research objectives by the ASC include: (1) assessing maintenance, transmission and dispersal of antibiotic resistant E. coli in gulls of Alaska, (2) quantifying prevalence of antibiotic resistant bacteria in wildlife and environmental sources across Alaska, and (3) determine migratory routes of large gull species that breeding in Alaska and are potential reservoir and dispersal agents of antibiotic resistant bacteria.
