The prevalence and antimicrobial susceptibility of in 512 poultry meat samples collected from retail stores and poultry-processing plants in Japan between 2015 and 2016 were investigated. The results showed that 55.9% of poultry meat samples were contaminated with , with nine different serotypes represented. The most frequent serovar was serovar Infantis, followed by . Schwarzengrund, together accounting for 78.2% of the isolates. High antimicrobial resistance rates were observed against tetracycline (80.9% . Infantis and 83.9% . Schwarzengrund), streptomycin (53.4% . Infantis and 76.8% . Schwarzengrund), and kanamycin (33.6% . Infantis and 82.1% . Schwarzengrund). All tested isolates were susceptible to colistin and ciprofloxacin. In addition, a high proportion (65.6% of Infantis, 85.7% of Schwarzengrund) of isolates were resistant to two or more antimicrobials, and 22 and 17 different resistance patterns were observed in the two strains, respectively. The predominant antibiotic resistance patterns were streptomycin-tetracycline (32/131, 24.4% of Infantis) and streptomycin-kanamycin-tetracycline-sulfamethoxazole/trimethoprim (43/112, 38.4% of Schwarzengrund). These data indicate that multidrug-resistant . Infantis and . Schwarzengrund have spread among poultry meat in Japan.
对2015年至2016年期间从日本零售店和家禽加工厂采集的512份禽肉样本中的[细菌名称未给出]的流行情况和抗菌药物敏感性进行了调查。结果显示，55.9%的禽肉样本被[细菌名称未给出]污染，呈现出9种不同的血清型。最常见的血清型是婴儿沙门氏菌血清型，其次是施瓦岑格鲁德沙门氏菌，两者合计占分离株的78.2%。观察到对四环素（婴儿沙门氏菌为80.9%，施瓦岑格鲁德沙门氏菌为83.9%）、链霉素（婴儿沙门氏菌为53.4%，施瓦岑格鲁德沙门氏菌为76.8%）和卡那霉素（婴儿沙门氏菌为33.6%，施瓦岑格鲁德沙门氏菌为82.1%）的高耐药率。所有测试的分离株对黏菌素和环丙沙星敏感。此外，很大比例（婴儿沙门氏菌的65.6%，施瓦岑格鲁德沙门氏菌的85.7%）的[细菌名称未给出]分离株对两种或更多种抗菌药物耐药，并且在这两种菌株中分别观察到22种和17种不同的耐药模式。主要的抗生素耐药模式是链霉素 - 四环素（32/131，占婴儿沙门氏菌的24.4%）和链霉素 - 卡那霉素 - 四环素 - 磺胺甲恶唑/甲氧苄啶（43/112，占施瓦岑格鲁德沙门氏菌的38.4%）。这些数据表明多重耐药的婴儿沙门氏菌和施瓦岑格鲁德沙门氏菌已在日本的禽肉中传播。
