Objective.确定是否可以在以农村为主的州的救护车中发现耐甲氧西林金黄色葡萄球菌（MRSA）。方法.样本从缅因州南部的51辆救护车的指定区域获得。在含有4 μ g/mL苯唑西林的甘露醇盐琼脂上测试这些样品。将所得菌落进行革兰氏染色，并测试过氧化氢酶和凝固酶的存在。结果在接受测试的51辆救护车中，25辆（49%）至少有一个区域MRSA污染呈阳性。结论.在缅因州南部运营的大量救护车存在MRSA污染，救护车可能是将潜在严重感染传播给患者和EMS人员的重要储存库。服务类型（火灾与非火灾）或年度呼叫量之间没有统计学差异。然而，提供24小时有偿服务的服务的污染率在统计上显著低于不提供这种服务的服务。
Objective. To determine whether methicillin-resistant Staphylococcus aureus (MRSA) could be found in ambulances in a predominantly rural state. Methods. Samples were obtained from specified areas in 51 ambulances in southern Maine. These samples were tested on mannitol salt agar containing 4 mu g/mL oxacillin. Resulting colonies were gram-stained and tested for the presence of catalase and coagulase. Results. Of the 51 ambulances tested, 25 (49%) had at least one area positive for MRSA contamination. Conclusions. A significant number of ambulances operating in southern Maine have MRSA contamination, and ambulances may represent an important reservoir for the transmission of potentially serious infections to patients and EMS personnel. There was no statistical difference between the service types (fire-based vs. non-fire-based) or annual call volume. There was, however, a statistically significant lower rate of contamination in services that provided paid, 24-hour coverage versus those that did not.
