肿瘤患者术后合并肺部耐甲氧西林葡萄球菌感染首选抗生素的初探

金黄色葡萄球菌为重要的病菌;表皮葡萄球菌及腐生葡萄球菌目前已成为重要的条件致病菌.本室选用 25株肿瘤术后患者痰培养中对甲氧西林耐药的葡萄球菌(MRSA、MRSE、MRSS),其MIC_90>128μg/ml,但丙氟哌酸对上述25株细菌则有较高的抗菌活性,其MIC_50为0.5μg/ml,MIC_90为4μg/ml.

The Study on the First Line Antibiotics in the Treatment of the Pneumal Methicillin-resistant Staphylococemia in Postoperative Patients with Cancer

Staphylococcus Aureus is one of the major pathogenic bacteria, especially its subvarietries such as the Epidermo-Staphylococcus and Saprozoic Staphylococcus have become essential conditioning morbific bacteria. Twenty five strains of Staphylococcus(MRSA,MRSE,MRSS)which are all Methicillin-resistant were selected from phlegm cultures of the postoperative patients with cancer for study. Their MIC90 values are greater than 128 ug/ml,but Ciprofloxain has higher antibiotic activaties to the above-mentioned 25 strains of bacteria, the MIC50 was 0. 5ug/ml,and MIC90 was about 4ug/ml,
