摘　　要：目的对筛选出眼科门诊物品表面中的甲氧西林敏感金黄色葡萄球菌(MSSA)和耐甲氧西林金黄色葡萄球菌(MRSA)进行调查以防止其传播。方法 2010年11月-2011年8月门诊1和门诊2分别取60个样本,共120个样本,分别对其中的门把手、电脑键盘、头枕接触表面取样,金黄色葡萄球菌所用K-B法鉴定到种。结果120个样本中检出MSSA24株、MRSA5株;通常发现被污染的地方有门把手、头枕及电脑键盘;24株MSSA中有3株为泛敏感菌、13株仅仅抗氨苄西林、3株耐氨苄西林和红霉素、5株MSSA耐氨苄西林、红霉素、克林霉素。结论眼科门诊经常接触的物品表面上检测出了金黄色葡萄球菌,因此,在这些被污染的经常性接触表面,需要定期的清理和消毒,以防止病原菌的繁殖传播。OBJECTIVE To screen out the methicillin‐susceptible Staphylococcus aureus （MSSA） and methicillin‐resistant Staphylococcus aureus （MRSA） strains isolated from the objects surfaces of ophthalmology clinics so as to prevent the spread of the strains .METHODS Totally 120 samples were collected from the outpatient depart‐ments ,including 60 samples from outpatient department 1 and 60 samples from outpatient department 2 ;the sur‐faces of the door handles ,computer keyboards ,and pillows were respectively sampled ,and the S .aureus strains were identified by using K‐B method .RESULTS A total of 24 strains of MSSA and 5 strains of MRSA have been i‐solated from the 120 samples .The door handles ,computer keyboards ,and pillows were the common contaminated places .Among the 24 strains of MSSA ,there were 3 strains of pan‐susceptible strains ,13 strains only resistant to ampicillin ,3 strains resistant to ampicillin and erythromycin ,and 5 strains resistant to ampicillin ,erythromycin , and clindamycin .CONCLUSION The S .aureus strains have been detected from the surfaces of the contaminated ob‐jects in the ophthalmology clinics ,therefore ,it is necessary to conduct regular cleaning and disinfection of the fre‐quent‐contact contaminated surfaces so as to prevent the reproduction and spread of the pathogens .
