【摘要】 目的探讨小儿肺炎的细菌学分类及其对抗生素的耐药性特点。方法通过痰培养分离菌株,再用药敏试验筛选抗生素。结果(1)分离菌中革兰氏阴性(G-)杆菌占首位,为68.00%,革兰氏阳性(G+)球菌占25.81%,真菌占6.2%。(2)所有检出的G-杆菌对多种抗生素耐药,对哌拉西林/他唑巴坦、阿米卡星、亚胺培南、美洛培南的耐药率较低;(3)所有检出的G+球菌对青霉素均有较高耐药性,对万古霉素、利福平敏感性较高。结论小儿肺炎病原菌以G-杆菌为主,注意合理应用抗生素,控制耐药菌的产生。更多还原

【Abstract】 Objective To investigate the bacterial classification and drug-resistance of pneumonia in children.Methods Isolates were identified by sputum bacterial culture,antibiotics were selected by susceptibility test.Results (1)The ratio of the gram-negative bacillus to total bacterial isolated was 68%,and the gram-positive bacillus was 25.81%,the fungi was 6.2%.(2)The gram-negative bacillus was multiresistant to commonly used antibiotics,and had high susceptibility rate to Piperacillin/Tazobactam,Amikacin,Imipenem and Meropenem.(3)The gram-positive bacillus isolated was multiresistant to Penicillin,and had high susceptibility rate to Vancomycin,Rifampicin.Conclusion The gram-negative bacillus play an important role in pneumonia in children.Using anti-bacterial drugs was rational,and control multiresistant to antibiotics produced.更多还原
