Abstract：
We investigate the role of black-headed gulls (Chroicocephalus ridibundus), an omnivorous species that is among the most likely wild bird candidates for transmission of zoonotic agents, as a potential reservoir of Campylobacter spp. Colonies with different anthropogenic pressures were studied to examine differences in exposure to sources of Campylobacter between rural and urban birds. We recorded Campylobacter spp. in 4.87% of adult black-headed gulls and 2.22% of their chicks after analysing 1036 cloacal swabs collected over two breeding seasons in three colonies in northern Poland. Campylobacter jejuni was found most frequently (85.72%), and Campylobacter lari and Campylobacter coli were much scarcer. Prevalence of Campylobacter did not differ significantly between black-headed gulls breeding in urban (4.27%) and rural (3.80%) habitats. Almost all isolates from chicks and adults were susceptible to azithromycin (97.62%) and erythromycin (95.24%), but fewer to tetracycline (50.00%) and ciprofloxacin (47.62%). Campylobacter prevalence was unrelated to the date of sampling. Our study indicates that black-headed gulls are carriers of resistant to antibiotics Campylobacter and they can contaminate natural waterbodies with their faeces, which poses a threat to human and farm animal health.
摘要：
我们研究了黑头海鸥（Chroicocephalusridibundus）的作用，杂食性物种，是最有可能传播人畜共患病原体的野生鸟类之一，作为弯曲杆菌属的潜在水库。研究了具有不同人为压力的菌落，以检查农村和城市鸟类对弯曲杆菌来源的暴露差异。我们记录了弯曲杆菌。在分析了波兰北部三个殖民地在两个繁殖季节收集的1036个泄殖腔拭子后，有4.87％的成年黑头海鸥和2.22％的雏鸡。空肠弯曲菌最常见（85.72%），而拉氏弯曲杆菌和大肠杆菌弯曲杆菌则更为稀少。城市（4.27％）和农村（3.80％）栖息地的黑头海鸥之间的弯曲杆菌患病率没有显着差异。几乎所有雏鸡和成虫分离株对阿奇霉素(97.62%)和红霉素(95.24%)敏感,但对四环素(50.00%)和环丙沙星(47.62%)较少。弯曲杆菌的患病率与采样日期无关。我们的研究表明，黑头海鸥是对抗生素弯曲杆菌耐药的携带者，它们可以用粪便污染天然水体，这对人类和农场动物健康构成威胁。
