초록

Appearance of drug-resistant bacteria is one of the most important issues worldwide that greatly impact both humans and wildlife. Previous studies proved that wild birds inhabiting in urban areas can be exposed to antibiotic-resistant bacteria, whose resistance might be derived from the antibiotics widely used in the medical facilities and farming areas. In these environments, wild birds can be a spreading vector for the resistance genes among the environmental bacteria. The Oriental magpie (Pica serica) is one of the wildlife species well known for high adaptability to urban habitats. Therefore, one can predict that the Oriental magpie is a potential carrier of the antibiotic-resistant microbes. In this study, we conducted disk susceptibility test and PCRs for antibiotic resistance genes and detected Escherichia coli carrying resistance to three antibiotic agents from the feces of 10 hatchlings and fledglings of the Oriental magpie living in the campus of Seoul National University (SNU). In addition, some individuals showed multi drug resistance. Our results show that nestlings and fledglings of the Oriental magpie are exposed to Escherichia coli harboring resistance to one or more antibiotic agents. In order to understand the origin and the transfer mechanisms of these microbes, more thorough investigation on the exposure of wildlife species living in a range of urban-rural gradients to the antibiotic resistant microbes should be conducted.
