Methicillin-resistant skin infections are an increasing concern in veterinary medicine, especially when found in juvenile dogs with no prior antimicrobial exposure. The objectives of this study were to assess the prevalence of methicillin-resistant staphylococci in breeding bitches and survey antimicrobial administration by their breeders. A total of 17 breeders and 54 bitches were included. Bitches were housed in diverse environments throughout the Phoenix, Arizona, USA metropolitan region. Nasal and oral gingival swabs were submitted for selective culture. Methicillin-resistant was not present, while methicillin-resistant was found in only 1/54 (1.9%) dogs. Survey results revealed that 16 bitches, which did not include the 1 MRSP-positive dog, had received antimicrobials within 6 months prior to sampling. Regardless of the low point prevalence identified, veterinarians and breeders should be cognizant of risks for bacterial resistance with the overuse of antimicrobials.
耐甲氧西林皮肤感染是兽医领域日益关注的问题，尤其是在没有先前抗菌药物暴露的幼年犬中发现时。本研究的目的是评估繁殖母犬中产耐甲氧西林葡萄球菌的流行率，并调查其饲养员的抗菌药物管理情况。共有 17 名饲养员和 54 只母犬参与了研究。母犬被安置在亚利桑那州凤凰城大都市地区不同的环境中。采集鼻腔和口腔牙龈拭子进行选择性培养。未发现耐甲氧西林金黄色葡萄球菌，但仅在 1/54（1.9%）的犬中发现了耐甲氧西林凝固酶阴性葡萄球菌。调查结果显示，在采样前 6 个月内，有 16 只母犬（不包括 1 只 MRSP 阳性犬）接受了抗菌药物治疗。尽管确定的点患病率较低，但兽医和饲养员应该意识到过度使用抗菌药物会导致细菌耐药的风险。
