摘要: 目的 了解儿童脑脊液培养的常见病原菌分布和体外耐药模式。方法 回顾分析2007 年1 月至2014 年12 月住院患儿脑脊液细菌培养结果。细菌鉴定和药敏试验采用法国生物梅里埃的Vitek 系统,部分菌株药敏试验采用纸片扩散法。结果 研究期间23 099例患儿至少送检脑脊液1次,分离出细菌671株,阳性率2.9%。其中革兰阳性菌579株(86.3%),革兰阴性菌92株(13.7%),排名前5位细菌依次为:凝固酶阴性葡萄球菌399株(58.9%)、微球菌37株(5.5%)、肺炎链球菌34株(5.1%)、大肠埃希菌32株(4.8%)、屎肠球菌26株(3.9%)。连续8年的脑脊液培养阳性率呈下降趋势(趋势χ2= 10.410,P = 0.001),凝固酶阴性葡萄球菌年度阳性率呈下降趋势(趋势χ2= 31.200,P < 0.001),大肠埃希菌年度阳性率则呈上升趋势(趋势χ2= 4.786,P = 0.029)。凝固酶阴性葡萄球菌对苯唑西林耐药率达79.8%,未发现耐利奈唑胺和耐万古霉素的凝固酶阴性葡萄球菌;微球菌对万古霉素敏感率为100%;肺炎链球菌对青霉素耐药率为77.8%,对万古霉素敏感率为100.0%;大肠埃希菌对哌拉西林/ 他唑巴坦和美洛培南的敏感率为100.0%。结论 脑脊液细菌培养阳性率低,凝固酶阴性葡萄球菌、微球菌、肺炎链球菌、大肠埃希菌、屎肠球菌是主要菌种。临床应根据培养阳性菌株、药敏结果合理选择抗菌药物。

Abstract: Objective To explore the common pathogens distribution and the drug resistance pattern in vitro from cerebrospinal fluid culture in children. Methods The results of cerebrospinal fluid culture in hospitalized children from January 2007 to December 2014 were retrospectively analyzed. Bacteria identification and antimicrobial susceptibility were assayed by Vitek system from Bio Mrieux Company. Some bacterial strains were tested by disk diffusion method. Results Cerebrospinal fluid from 23099 patients were tested at least one time during research period. 671 strains of bacteria were isolated with positive rate of 2.9%, among which there were 579 strains of gram positive bacteria (86.3%) and 92 strains of gram negative bacteria (13.7%). The top five bacteria were coagulase negative Staphylococcus (399 strains, 58.9%), Micrococcus (37 strains, 5.5%), Streptococcus pneumoniae (34 strains, 5.1%), Escherichia coli (32 strains, 4.8%), and Enterococcus faecium (26 strains, 3.9%). The positive rates of cerebrospinal fluid culture in 8 consecutive years showed a downward trend (χ2 = 10.410, P = 0.001). The positive rates of coagulase negative Staphylococci showed annual decline trend (χ2 = 31.200, P < 0.001). However, annual positive rates of Escherichia coli showed an upward trend (χ2 = 4.786, P = 0.029). The resistant rate of coagulase negative Staphylococcus to oxacillin was 79.8%, and no coagulase negative Staphylococcus resistant to linezolid and vancomycin was found. Micrococcus sensitive to vancomycin was 100%. The resistant rate of Streptococcus pneumoniae to penicillin was 77.8%, while the sensitive rate of Streptococcus pneumoniae to vancomycin was 100%. The sensitive rate of Escherichia coli to piperacillin/tazobactam and meropenemwas 100%. Conclusions The positive rate of cerebrospinal fluid culture is low. The main strains are coagulase negative Staphylococcus, Micrococcus, Streptococcus pneumoniae, Escherichia coli, and Enterococcus faecium. The antibiotics should been rationally chosen according to the results of bacterial strain culture and drug sensitive test.
