Methicillin-resistant (MRSA) and are important human pathogens that are also carried by animals. The role of wild mammals on farms in their maintenance and transmission, however, is poorly understood. To determine if Norway rats are potential carriers of these bacteria on Canadian farms, we tested 21 rats from swine farms in Ontario. The MRSA spa type t034 was isolated from 1 (4.8%) rat. This livestock-associated strain often colonizes pigs and pig farmers, suggesting that transmission among rats and pigs or environmental transmission is possible on pig farms. ribotype 078 was isolated from 1 rat from a different farm. This strain is associated with infection in piglets, calves, and humans. The identification of MRSA and in Norway rats on farms in Canada adds to the growing knowledge about the role of rats in the ecology of these pathogens. Further studies are required to determine if rats play a part in the epidemiology of these pathogens on farms.
耐甲氧西林金黄色葡萄球菌(MRSA)等是重要的人类病原体,动物也会携带。然而,农场中的野生哺乳动物在这些病菌的存续和传播中所起的作用却鲜为人知。为了确定挪威大鼠是否是加拿大农场中这些细菌的潜在携带者,我们检测了安大略省养猪场的21只大鼠。从1只(4.8%)大鼠身上分离出了MRSA spa型t034。这种与家畜相关的菌株常定植于猪和养猪户身上,这表明在养猪场大鼠与猪之间可能存在传播,或者存在环境传播。从另一个农场的1只大鼠身上分离出了核糖体分型078。该菌株与仔猪、犊牛和人类的感染有关。在加拿大农场的挪威大鼠身上鉴定出MRSA和[未提及的细菌名称],这增加了人们对大鼠在这些病原体生态中作用的认识。需要进一步研究以确定大鼠是否在农场中这些病原体的流行病学中发挥作用。
