摘要
对临床分离的１０７株葡萄球菌用经典方法进行ＭＲＳＡ和ＭＲＳＥ鉴定与耐药性研究。结果表明：金黄色葡萄球菌和表皮葡萄球菌占待测葡萄球菌的９４．４％，而ＭＲＳＡ和ＭＲＳＥ分别为４５．２％和１６．９％，ＭＲＳＡ比ＭＲＳＥ更多见（Ｐ＜０．０１）。两者产生β－内酰胺酶的阳性率分别比ＭＳＳＡ和ＭＳＳＥ高（Ｐ＜０．０５和Ｐ＜０．０１），耐药率亦分别高于ＭＳＳＡ和ＭＳＳＥ（Ｐ＜０．０１和Ｐ＜０．０５），均为６重以上耐药菌。
MRSA and MRSE were identified by detecting oxacillin resistance of 107 strains of staphylococci from clinical sources. The positive rates of MRSA and MRSE were 45.2% and 16.9%, respectively among the whole number of staphylococci examined. Antibioticresistant strains were detected with disks by KirbyBauer method. All MRSA and MRSE strains were multiresistant. Resistant rates of MRSA and MRSE were higher than MSSA and MSSE. The positive rates of βlactamase producing in MRSA and MRSE were significantly higher than MSSA and MSSE (P<0.05 and P<0.01) respectively. These results indicated that MRSA and MRSE were the main pathogens in the clinical infection. MRSA and MRSE detection are important for the early diagnosis and treatment of patients with infective diseases.
