摘要: 目的  了解昆明地区结核病患者和疑似结核病患者中Mtb培养检测情况和耐药情况。方法  收集1928例结核病患者和疑似结核病患者2046份标本,包括痰、支气管刷检物或肺泡灌洗液、胸腹腔积液、脑脊液、尿液、脓液、其他标本(淋巴液、心包积液、分泌物、穿刺液等)。使用BACTEC MGIT 960全自动分枝杆菌快速培养仪和中性罗氏培养基进行培养,分别记录初始抗酸涂片结果,BACTEC MGIT 960全自动分枝杆菌快速培养仪、中性罗氏培养基报告阳性后的涂片结果。分别对培养时间、培养阳性率、培养污染率及5种一线抗结核药物(S、INH、RFP、EMB和PZA)的耐药情况作统计分析。结果  BACTEC MGIT 960全自动分枝杆菌快速培养仪和中性罗氏培养基阳性率分别为38.2%(782/2046)和32.6%(666/2046);结核诊断率37.3%(719/1928);抗结核一线药耐药率为41.9%(212/506),耐多药率(至少同时耐INH和RFP)为20.0%(101/506)。结论  昆明地区结核病患者对一线抗结核药物耐药情况严重。

Abstract: Objective  To understand the culture and drug-resistance of  Mycobacterium tuberculosis in Kunming area. Methods  The specimens from the tuberculosis (TB) patients and suspected TB patients were examined by BACTEC MGIT 960, Roche culture and acid-fast bacilli (AFB) smear. The incubation time, culture positive rate, and contamination rate were analyzed. The 5 first-line anti-TB drug (streptomycin, isoniazid, rifampin, ethambutol, pyrazinamide) resistances were detected, respectively. Results  The culture positive rate was 38.2%(782/2046),by BACTEC MGIT 960. Roche culture positive rate was 32.6% (666/2046). The TB diagnosis rate was 37.3% (719/1928). First-line anti-TB drug-resistant rate was 41.9% (212/506),and multidrug-resistant rate was 20.0% (101/506). Conclusion  Tuberculosis patients resistence is serve to first-line anti-TB drug in Kunming area.
