摘要: 目的评价显微镜观察药物敏感性检测(MODS,microscopic observation drug suscepti-bility assay)方法用于分枝杆菌分离培养和直接药物敏感性测定的应用前景。方法应用MODS方法对113例涂片镜检阳性患者痰标本进行分离培养,同时进行异烟肼、利福平、链霉素、乙胺丁醇4个药物的直接药物敏感性测定,以罗氏法分离培养和间接绝对浓度法作为对照,对分离培养和药敏结果进行对比分析,并通过DNA序列分析对不一致药敏结果进一步验证。结果 MODS与罗氏法分离培养的阳性率均为83.2%,污染率分别为0%和2.7%,两方面差异无统计学意义,两者的符合率为93.6%(kappa值:0.75),培养的敏感性、特异性分别为95.7%、81.3%。MODS的分离培养中位数时间为10 d(第95百分位数为21.5 d),罗氏分离培养的中位数时间为25 d(第95百分位数为39.3d)。MODS与间接绝对浓度法的耐药株检出率分别为49.5%、47.8%,符合率为95.5%(kappa值:0.91)差异无统计学意义,MODS检测的敏感性、特异性分别为97.7%、93.3%。MODS对结核分枝杆菌检测的...

Abstract: Objective To assess the value of microscopic observation method(MOM) on mycobacteria culture and drug sensitivity assay.Methods The smear-positive sputum specimens were cultured and directly determined the drug-susceptibility test on isoniazid(INH),rifampicin(RFP),streptomycin(SM) and ethambutol(EMB)with MOM,compared with conventional culture on Lǒwenstein-Jensen(L-J) medium and drug susceptibility testing using the absolute concentration method.The inconsistent results were further detected with DNA suquen...
