4地儿科临床分离革兰阳性球菌2000-2006年耐药性监测

目的探讨我国不同地区医院儿科主要革兰阳性球菌耐药的情况。方法对2000年1月1日至2006年12月31日5所儿童专科医院检验科报送检标本分离出的4种革兰阳性球菌用Kirby-Bauer琼脂扩散法进行抗生素敏感实验。结果5所医院临床分离出金黄色葡萄球菌共7825株,其中耐甲氧西林金黄色葡萄球菌(methicillin-resistant staphylococcus aureus,MRSA)的检出率为6.87%,红霉素总耐药率为66.39%,并且有逐年上升趋势,未发现对万古霉素耐药或中度敏感菌株。分离出肺炎链球菌4781株,其中青霉素不敏感肺炎链球菌(PNSP)的平均检出率为68.64%,红霉素耐药率为90.80%,两者耐药率均逐年上升。分离出1301株β溶血性链球菌,对青霉素全部敏感,对红霉素的耐药率为80.94%,且耐药率在逐年增加。分离出肠球菌共2216株,对万古霉素的中度敏感率为3.11%,氨苄西林的耐药率为48.03%,红霉素的耐药率高达86.47%。结论除β溶血性链球菌外,多数革兰阳性菌对广谱青霉素的耐药率都偏高;对红霉素的耐药率居高不下并有逐年上升的趋势,革兰阳性菌对万古霉素和环丙沙星的敏感率较高。MRSA仍在较低水平,本研究未发现耐万古霉素金黄色葡萄球菌(VRSA),但出现对万古霉素中度敏感耐药的肠球菌。因此要加强对革兰阳性球菌耐药性和抗生素使用情况的监测,合理使用抗生素。

Susceptibility Surveillance of Gram-positive Bacteria to Antibiotics Among Children in China:A Study in Beijing,Shanghai,Guangzhou and Chongqing during the Period of 2000-2006

Objective To obtain a better insight of the drug-resistance rate of gram-positive cocci isolated from patients of 5 pediatric hospitals located in different areas of China.Methods From Jan 1st 2000 to Dec 31st 2006,a total of four type pathogenic strains were isolated from 5 pediatric hospitals which are Beijing Children's Hospital,Children's Hospital of Fudan University,Shanghai Children's Hospital,Guangzhou Children's Hospital and Chongqing Children's Hospital with both hospital acquired infection(HAI)and...
