摘　　要：目的了解儿童感染肺炎链球菌临床分离株对各类抗菌药物的耐药状况及特点。方法对从温州医学院附属育英儿童医院2005年1月-2006年12月住院患者送检标本中分离到的203株肺炎链球菌,进行10种抗菌药物敏感性试验,其中对青霉素进行8个药物浓度检测。结果203株肺炎链球菌中,万古霉素未检出耐药菌株,敏感率为100.0%;左氧氟沙星对肺炎链球菌也显示了很好的抗菌活性,敏感率为98.0%;青霉素、红霉素、克林霉素、四环素和复方新诺明对肺炎链球菌的敏感性很低,均<15.0%。对青霉素的不敏感率达86.2%,MIC值≥4μg/ml的菌株占了总数的11.8%。结论肺炎链球菌临床检出株对大多数常用抗菌药物的耐药性强,多重耐药菌比例很高;肺炎链球菌对万古霉素和左氧氟沙星最为敏感,其次是氯霉素;克林霉素、四环素、红霉素和复方新诺明已不是治疗肺炎链球菌的有效药物。OBJECTIVE To investigate conditions and features of antimicrobial resistance in Streptococcus pneumoniae clincal isolates.METHODS Totally 203 strains of S.pneumoniae were isolated from Jan 2005 to Dec 2006 in Yuying Pediatric Hospital of Wenzhou Medical College.Then the antimicrobial susceptibility test to ten drugs and the MICs of penicillin were detected.RESULTS In 203 S.pneumoniae strains,all were sensitive to vancomycin,were sensitive to 98.0%,levofloxacin,the sensitivity of penicillin,erythromycin,tetracycline,clindamycin and SMZ was lower than 15.0%.The penicillin insensitivity of 203 strains reached 86.2%.There were 24 of the 203 strains for which penicillin MICs were ≥4 μg/ml.CONCLUSIONS S.pneumoniae clinical strains are resistant to most of the commonly used antibiotics.The percentage of high level multidrug resistant strains is very high.Vancomycin and levofloxacin are the most sensitive drugs for S.pneumoniae clinical strains,the next are chlorophenicol.Erythromycin,SMZ,tetracycline and clindamycin aren′t useful in treating S.pneumoniae infection.
