Conclusion : MRSA showed multiple resistance to antibiotics , the drug-resistant rate to 12 kinds of antibiotics was statistically and significantly higher than that of MSSA .

耐万古霉素金黄色葡萄球菌占3.3%（4/122）。结论：耐苯唑西林的金黄色葡萄球菌表现为多重耐药性，且对12种抗生素的耐药率明显高于苯唑西林敏感的葡萄球菌，P0.01。

Both MRSA and MSSA were susceptible to Vancomycin .

MRSA与MSSA皆对万古霉素敏感。

The incidence of MRSA and MSSA producing β - lactamase was 60 % and 83.3 % ; the total rate was 63.4 % .

金黄色葡萄球菌的产β-内酰胺酶的产酶率为63.4%，MRSA和MSSA产酶率分别为60%和83.3%。

CONCLUSIONS : Multiresistant phenotypes of MRSA were different , and also antimicrobial resistance of MRSA and MSSA was some differences between Beijing and Hubei regions .

结论：北京和湖北地区MRSA表型多重耐药谱存在差别，MRSA和MSSA对抗生素耐药性也有不同。

Results : Cefathiamidine had a stronger antibacterial activity to S. pneumoniae , S. pyogenes , MSSA , MSSE and B. catarrhalis .

结果：头孢硫脒对肺炎球菌、化脓性链球菌、MSSA、MSSE和卡他布汉氏菌有较强的抗茵活性。

Methods All isolated S.aureus were distinguished into methicillin resistant Staphylococcus aureus ( MRSA ) and methicillin sensitive staphylococcus aureus ( MSSA ) with salt agar screening method .

方法对临床分离的金葡菌用琼脂筛选法区分耐甲氧西林金葡菌（MRSA）和甲氧西林敏感金葡菌（MSSA）；

The resistance rate and the multi resistant rate of methicillin resistant staphylococcus ( MRS ) for the 14 kinds of antibiotics were higher as compared with those of methicillin sensitive ( MSSA ) .

耐甲氧西林敏感葡萄球菌对14种常用抗生素的耐药性及多重耐药性均高于甲氧西林敏感葡萄球菌；

The PVL + isolate rate of MRSA ( 5.0 % ) was higher than that of MSSA ( 9.0 % ), but there was no statistic meaning ( P > 0.05 );

PVL+菌株在MRSA中的分离率（5.0%）高于MSSA（9.0%）但；

Conclusion Expression level of femA in high-level MRSA was significant higher than that in low-level MRSA and MSSA . femA was essential for the expression of high-level methicillin resistance in MRSA .

结论非产酶金黄色葡萄球菌femA的表达水平在甲氧西林高水平耐药组中高于低水平耐药组和敏感组，femA是耐甲氧西林金黄色葡萄球菌高水平耐药表达的必需因子。

MRSA showed multiresistance to 15 of 18 antibiotics with rates ranging from 28 % to 100 % , and most of MSSA were only resistant to Penicillin G and Ampicillin .

此外，MRSA对18种抗生素中的15种呈现多重耐药，耐药率介于28%～100%。

Methods 16 MRSA and 24 MSSA strains were used in this study . The aminoglycoside resistant genes were detected by PCR and aminoglycoside resistance was tested by Kirby-Bauer method to 4 kind of antibiotics ( Amikacin Gentamicin Netilmicin Tobramycin ) .

方法运用K-B法和PCR方法分别对16株MRSA和24株MSSA4种氨基糖苷药物（丁胺卡那霉素、奈替米星、庆大霉素、妥布霉素）耐药性和氨基糖苷类耐药基因进行检测。
