Abstract

Wild birds are important indicators and potential spreaders of antibiotic resistance. The order Passerines is scarcely studied apart from Corvus sp. but extended spectrum beta-lactamases (ESBLs) has been found in Blackbirds. We tested 300 fecal samples from a well-studied population of Collared Flycatchers (Ficedula albicollis) at the Island of Gotland in Sweden and found no ESBL-producing bacteria. These results support the idea of 'ecological guild' as Blackbirds are ground-foraging invertebrate feeders, whereas Collared Flycatchers are aerial insectivores not regularly coming into contact with fecal contaminations and therefore less prone to acquire pathogens spread by the fecal-oral route.

摘要

野生鸟类是抗生素耐药性的重要指示物种和潜在传播者。除了鸦科鸟类外,雀形目鸟类几乎未被研究,但在乌鸫中发现了超广谱β-内酰胺酶(ESBLs)。我们检测了来自瑞典哥特兰岛一个经过充分研究的白领姬鹟(Ficedula albicollis)种群的300份粪便样本,未发现产ESBLs的细菌。这些结果支持了“生态群落”的观点,因为乌鸫是地面觅食的无脊椎动物捕食者,而白领姬鹟是空中食虫动物,不经常接触粪便污染,因此不太容易通过粪-口途径获得病原体传播。
