[font face=Serif][font size=5]Gulls in Alaska Found to Carry Antibiotic Resistant E. coli[/font]
Release Date: September 26, 2016
[font size=4]ANCHORAGE, Alaska — Some gulls in southcentral Alaska are carriers of antibiotic resistant strains of E. coli, according to a new study co-authored by the U.S. Geological Survey.[/font]
[font size=3]Gulls commonly carry E. coli and often show no signs of illness. However, this is the first report of antibiotic resistant E. coli in birds in the southcentral Alaska region. While it is still unclear how gulls are picking up antibiotic resistant strains of E. coli, possible sources include landfills and wastewater discharge.
USGS and collaborators sampled gulls on the urban Kenai Peninsula and on the remote Middleton Island, a location far offshore in the Gulf of Alaska. The samples were tested, and results show more antibiotic resistant bacteria in birds in areas with higher levels of human use. Areas tested on the Kenai Peninsula’s Soldotna Landfill and the mouth of the Kenai River were chosen because of earlier water quality sampling performed by the Alaska Department of Environmental Conservation near these areas.
“More than half of the E. coli collected from gulls on the Kenai Peninsula were resistant to at least one antibiotic compound, and a large number of multi-resistant E. coli strains were detected,” said Andy Ramey, a USGS Alaska Science Center scientist and co-author of the report. “This is higher than the number of resistant strains identified at more remote gull colonies on Middleton Island.”
“Our findings suggest an increased level of antibiotic resistant bacteria in birds associated with urban environments,” said Dr. Jonas Bonnedahl, an infectious disease physician at Kalmar County Hospital in Sweden and senior author of the study. “Based on our findings, additional research may be warranted to understand the risk for re-transmission of antibiotic resistant E. coli to humans in locations where people and gulls interact.”
