目的:研究肺结核合并院内获得性肺炎的病原学特征;方法:选择2012年6月-2013年5月入住我院的肺结核合并院内获得性肺炎患者68例,采集患者痰液标本,进行连续三次以上的标本培养。使用自动细菌鉴定与药敏测试仪对细菌进行检验。统计致病病原菌及耐药情况;结果:痰液检测阳性患者65例,致病病原菌株85株,其中革兰氏阳性菌21株(24.71%),革兰氏阴性菌50株(58.82%),真菌14株(16.47%)。致病病原菌占第一位的是肺炎克雷伯杆菌,约占总病原菌株的24.71%,其次为铜绿假单胞菌,约占总病原菌株的,14.12%。所有培养的菌株对于不同抗生素具有不同的耐药性;结论:针对肺结核合并院内获得性肺炎病原学进行研究,能够准确掌握病原菌及其耐药性,对于疾病的治疗具有十分重要的意义。
Objective: To study the etiological characteristics of pulmonary tuberculosis complicated with acquired pneumonia in our hospital.Methods: Sixty-eight patients with pulmonary tuberculosis complicated with acquired pneumonia who admitted to our hospital from June 2012 to May 2013 were selected and their sputum specimens were collected for more than three times The specimen culture. Bacteria are tested using an automated bacterial identification and susceptibility tester. Sixty-five patients were positive for sputum test, and 85 were pathogenic pathogens. Among them, 21 strains (24.71%) were Gram-positive bacteria, 50 strains (58.82%) were gram-negative bacteria, , 14 fungi (16.47%). Pathogenic bacteria accounted for the first place is Klebsiella pneumoniae, accounting for about 24.71% of the total pathogen strains, followed by Pseudomonas aeruginosa, accounting for about 14.12% of the total pathogenic strains. All strains cultured had different resistance to different antibiotics. CONCLUSION: To study the etiology of pulmonary tuberculosis complicated with nosocomial pneumonia can accurately understand the pathogens and their drug resistance and is of great significance for the treatment of diseases.
