Chicken is a major source of human campylobacteriosis. Chicken meat originates not only from broilers but also from spent layers; however, few reports have documented the prevalence and antimicrobial resistance of Campylobacter spp. in layers in Japan. Therefore, we investigated the prevalence and antimicrobial susceptibility of Campylobacter spp. in 47 layer farms in Japan. Fecal samples were collected from the youngest and oldest flocks on the farm, and Campylobacter spp. was isolated from 46/47 (97.9%) farms. Among the C. jejuni isolates, the resistance rates to ampicillin, tetracycline, and ciprofloxacin were 29.6%, 22.2%, and 19.8%, respectively. The ciprofloxacin resistance rate (7.3%) in C. jejuni isolated from old flocks was significantly (P<0.01) lower than that in young flocks (32.5%).
鸡肉是人类弯曲杆菌病的主要传染源。鸡肉不仅来源于肉鸡,也来源于淘汰蛋鸡;然而,在日本,鲜有关于蛋鸡中弯曲杆菌属的流行情况和耐药性的报道。因此,我们调查了日本 47 家蛋鸡场中弯曲杆菌属的流行情况和药敏性。从农场中最年轻和最年长的鸡群中采集粪便样本,47 家(97.9%)农场中均分离出了弯曲杆菌属。在分离出的空肠弯曲杆菌中,对氨苄西林、四环素和环丙沙星的耐药率分别为 29.6%、22.2%和 19.8%。从老鸡群中分离出的空肠弯曲杆菌中,环丙沙星的耐药率(7.3%)明显(P<0.01)低于幼鸡群(32.5%)。
