The wide occurrence of antimicrobial‐resistant (AMR) bacteria in various environments is of great concern. Here, we examined the prevalence and antimicrobial susceptibility of Enterobacteriaceae isolated from 88 wild arthropods, collected in Gifu city, Japan. In total, 168 isolates of Enterobacteriaceae were obtained from 61 arthropods. All isolates were susceptible to all the antimicrobial agents tested, except colistin (31 isolates) and kanamycin (one isolate). The aph(3′)‐Ia gene, responsible for kanamycin resistance, was detected in Klebsiella oxytoca. Although synanthropic arthropods (houseflies and cockroaches) serve as vectors for AMR Enterobacteriaceae, other wild arthropods are not crucial carriers of Enterobacteriaceae resistant to antimicrobial agents.

日本岐阜市节肢动物分离肠杆菌科细菌耐药性

抗菌素耐药（AMR）细菌在各种环境中的广泛存在引起了人们极大的关注。在这里，我们检查了从日本岐阜市收集的 88 种野生节肢动物中分离出的肠杆菌科细菌的流行率和抗菌药物敏感性。总共从 61 种节肢动物中获得了 168 株肠杆菌科细菌。除了粘菌素（31 个分离株）和卡那霉素（1 个分离株）外，所有分离株都对所有测试的抗菌剂敏感。在催产克雷伯菌中检测到了导致卡那霉素抗性的aph (3')-Ia 基因。尽管合人类节肢动物（家蝇和蟑螂）是 AMR 肠杆菌科的载体，但其他野生节肢动物并不是对抗菌剂具有抗性的肠杆菌科细菌的重要载体。
