临床感染标本中常见革兰氏阳性球菌的分离及其耐药性分析

目的 :分析临床感染标本中常见革兰氏阳性球菌的分离及其耐药性 ,指导临床合理用药。方法 :采用美国NCCL S药敏试验纸片扩散法 ,检测 2 0 0 0年 8月至 2 0 0 2年 8月临床感染标本中分离的革兰氏阳性球菌的耐药性。结果 :两年中分离的革兰氏阳性球菌以葡萄球菌和肠球菌为主 ,其检出率分别为 5 3.6 %和 33.6 %。葡萄球菌除对万古霉素都敏感外 ,对苯唑西林耐药的葡萄球菌的耐药率明显高于对苯唑西林敏感的葡萄球菌。分离出 2 5 .2 %的肠球菌氨基糖甙类高耐株 (HL AR)和 1.8%的耐万古霉素肠球菌 (VRE)。结论 :合理使用抗生素对延缓细菌耐药性的产生及多重耐药菌株的传播与流行是非常重要的

Analysis of Isolated Rate and Drug Resistance of Main Gram-positive Cocci in Clinical Infectious Sampls

Objective To study the isolated rate and drug resistance of main gram positive cocci in clinical infecious sample and to help doctor to use antibiotics rationally. Methods The U.S. NCCLS antibacterial disk susceptibility test was used to detect the drug resistance of main Gram positive cocci in clinical infecious sample from august 2000 to august 2002. Results The isolated bacteria of main gram postive cocci were staphlococcus and enterococci, and their Rates were 53.0 % , 33.6 % respectively in the two years. The drug resistance of Oxaillin resistance staphylococcus was apparently higher than Oxaillin susceptible strphylococcus. The isolated rate of aminoglycoside resistance strains to enterococci (HLAR) and drug resistance enterococci to vancomycin (VRE) were 25.2 % and 1.8 % respectively. Conclusion It is very important to use antibiotics rationally for delaying the production of antimicrobial resistance of the bacteria and the spreading of some multi drug resistant organisms.
