目的探究吉木萨尔县肺结核病人痰结核分枝杆菌培养结果及影响因素。方法选择吉木萨尔县2015年2月-2017年4月之间的90例肺结核病人作为本次试验的研究对象,分别采集即时痰液以及次日晨起痰液,根据收集时间不同将痰液分为即时痰组和晨起痰组,进行结核分枝杆菌培养,记录培养结果并分析其影响因素。结果即时痰组液体变色培养基的培养时间为(27.3±6.2)d,阳性率为73.33%,改良罗氏培养基的培养时间为(55.6±11.5)d,阳性率为74.44%;晨起痰组变色培养基的培养时间为(26.9±6.8)d,阳性率为88.89%,改良罗氏培养基的培养时间为(56.1±10.9)d,阳性率为85.56%。结论不同培养基、不同标本采集时间均对培养结果有影响,在进行痰结核分枝杆菌培养时选择晨痰可提高检出率,选择液体变色培养基可相对缩短培养时间。
Objective To explore the results and influential factors of sputum Mycobacterium tuberculosis in patients with tuberculosis in Jimsar County. Methods Ninety patients with tuberculosis in Jimusar County between February 2015 and April 2017 were selected as the subjects of this study. Instant sputum and sputum were collected from the next morning. According to different collection time, sputum Divided into instant sputum group and morning sputum group, the Mycobacterium tuberculosis culture, record the culture results and analyze the influencing factors. Results The incubation time of liquid color change medium in instant sputum group was (27.3 ± 6.2) d, the positive rate was 73.33%, the culture time in modified Roche medium was (55.6 ± 11.5) days, the positive rate was 74.44% The culture time of color change medium was (26.9 ± 6.8) d, the positive rate was 88.89%, the culture time of modified Roche medium was (56.1 ± 10.9) d, the positive rate was 85.56%. Conclusion Different culture media and different specimen collection time have an impact on the culture results. Selecting sputum as sputum during the culture of sputum Mycobacterium tuberculosis can increase the detection rate. Choosing liquid color change medium can shorten the culture time relatively.
