| 目的<\b> 了解临床分离的耐甲氧西林的金黄色葡萄球菌(MRSA)对医院常用消得剂的抗性。方法<\b> 测定碘伏和氯已定对MRSA、甲氧西林敏感的金黄色葡萄球菌(MSSA)和金鱼色葡萄球菌ATCC6538的最小抑菌浓度(MIC)。结果<\b> 碘伏对MRSA的MIC明显高于MSSA,在38株MRSA中5.3％菌株的MIC是质控菌株的2倍,28.95％菌株的MIC为质控菌株的1.5倍,而18株MSSA中仅有11.1％菌株的MIC是质控菌株的1.5倍,83.3％菌株的MIC值与质控菌株相同。醋酸氯已定对MRSA、MSSA和金黄色葡萄球菌ATCC6538的MIC值相同。结论<\b> 部分MRSA菌株对碘伏抗性增高,MRSA对氯已定的抗性无明显增强,因此当有抗性菌株存在时应提高碘伏的浓度 |

| Objective<\b> To study the resistance of methicillin--resistant staphylococcus aureus (MRSA),an indicator used in hospitals. Methods<\b> We used minimal inhibitory concentrations(MIC) of iodoph and chlorhexidine to MRSA, methicillin--sensitive staphylococcus aureus (MSSA) and staphylococcus aures ATCC6538. Results<\b> Obvious difference between MRSA and MSSA the MIC of lodophor was noticed. Among MICs, 5. 3 % MRSA strains were 2--folds and 28. 9 % MRSA strains were 1. 5 fold more than staph. aures ATCC6538, while the MIC of 11. 1 % MSSA strains raised 1. 5 fold than ATCC6538. The MIC of 83. 3 % MSSA strains were the same to staph. aureus ATCC6538. The MIC of chlorhexidine to MRSA, MSSA and staphyloccus aureus ATTC6538 were similar to each other. Conclusion<\b> Results<\b> showed that some MRSA were more resistant to Iodophor than staph. aureus ATCC6538, but remained the same resistance to Chlorhexidine. Thus the concentrationn of Iodophor should be raised when the resistant strains were isolated. |
