2012年我院常见病原菌分布特点及耐药性监测

目的了解我院2012年感染性疾病中常见病原菌分布特点及耐药情况,指导临床规范使用抗菌药物。方法分析我院各类培养标本所分离的病原菌及药敏结果。结果 13241份标本中,分离出细菌2480株,其中革兰阳性菌1099株(44.31%),革兰阴性菌935株(37.70%),真菌446株(17.98%);革兰氏阳性菌中以表皮葡萄球菌、溶血葡萄球菌、金黄色葡萄球菌最多见,分别占14.80%、6.61%、4.72%;革兰氏阴性菌以大肠埃希菌、肺炎克雷伯菌、铜绿假单胞菌、鲍曼不动杆菌最为常见,分别占11.65%、5.36%、4.03%、2.86%;真菌以白色念珠菌最多,占74.66%。结论根据2011年CHINET数据统计,我院耐药菌株对抗菌药耐药率有升高的趋势。

Pathogenic bacteria distribution and drug resistance monitoring in 2012

Objective To investigate the bacterial distribution and antibiotic resistance situation for the guidance of rational use of antibiotics. Methods The distribution of isolated pathogenic bacteria and the drug sensitivity results of patients were analyzed. Results There were 2480 strains bacteria separated from 13241 specimens, which included 1099 strains of gram-positive bacteria （44.31%）, 935 strains of gram negative bacteria （37.70%） and 446 strains of fungus （17.98%）. Gram-positive bacteria included epidermis staphylococcus （14.80%）, hemolysis staphylococcus （6.61%） and aureus were accounted （4.72%）. Gram-negative bacteria included e.coli pneumonia （11.65%）, crayresearch bacterium （5.36%）, pseudomonas aeruginosar （4.03%） and acinetobactebaumannii （2.86%）. Candida albicans accounted for 74.66%. Conclusion According to CHINET of 2011 statistics, drug-resistant strains of antibacterial drug resistant rate has a tendency to rise. The management of antimicrobial should be strengthened.
