目的：为了评估耐甲氧西林葡萄球菌（MRS）定植在临床正常的狗和马在community.Methods和Results：三百临床正常的马和200临床正常的狗的患病率。从每匹马采集一个鼻拭子。从每只犬中采集两个拭子：（i）前鼻孔，和（ii）会阴区和肛门内0.5 cm处的组合。进行富集培养。未发现耐甲氧西林金黄色葡萄球菌（MRSA）。从三只犬的鼻拭子中分离出耐甲氧西林中间葡萄球菌（MRSI）。从126/300（42%）的马和26/200（13%）dogs.Conclusions：目前MRSI不被认为是一个显着的人畜共患疾病的关注，但它可能成为一个重要的病原体在狗的耐甲氧西林凝固酶阴性葡萄球菌（MRCoNS）。MRCoNS主要在受损的人类或动物宿主中引起疾病。然而，这些细菌可以作为水库的阻力决定因素在社会上，这可能会导致新的MRSA straines.Significance和影响的研究：这是第一次报告的患病率MRS殖民在临床正常的狗在社区设置。继续监测表明，以确定MRSA是否会出现在动物种群中，并成为动物疾病和人畜共患病感染的关注。
Aims: To evaluate the prevalence of methicillin-resistant staphylococcal (MRS) colonization in clinically normal dogs and horses in the community.Methods and Results: Three hundred clinically normal horses and 200 clinically normal dogs were enrolled. One nasal swab was collected from each horse. Two swabs were taken from each dog: (i) from an anterior nare, and (ii) a combination of the perineal area and 0.5 cm into the anus. Enrichment cultures were performed. Methicillin-resistant Staphylococcus aureus (MRSA) was not identified. Methicillin-resistant Staphylococcus intermedius (MRSI) was isolated from the nasal swab from three dogs. Methicillin-resistant coagulase negative staphylococci (MRCoNS) were isolated from 126/300 (42%) horses and 26/200 (13%) dogs.Conclusions: At present MRSI is not considered to be a significant zoonotic concern; however, it may become an important pathogen in dogs. MRCoNS mostly cause disease in compromised human or animal hosts. However, these bacteria can serve as reservoirs of resistance determinants in the community, which could lead to the emergence of novel MRSA strains.Significance and Impact of the Study: This is the first report of the prevalence of MRS colonization in clinically normal dogs in a community setting. Continued surveillance is indicated to determine whether MRSA will emerge in the animal population and become a concern for animal disease and zoonotic infection.
