【摘要】 作者根据分支杆菌在生长代谢过程中产生CO₂的特点,采用气相色谱法测定了肺结核及可疑肺结核患者78例的分支杆菌临床分离株在改良罗氏培养基中的CO₂含量,借以判断分支杆菌的耐药情况,并用常规方法作为对照。结果表明:两法符合率为83.3％,气相色谱法能比常规方法提前20天出结果。更多还原

【Abstract】 This test ls based on the phyiologiccharaeter of mycobacterium,which produ-ces carbon dioxide（CO₂）during its growth.Lowenstein-Jensen media CO₂ contents-were measured by gas chromatographyfor datermining drug-resistance of myco-bacteria.This was compared with the rou-tine method. Seventy-eight mycobacteriawere isolated from suspected tuberculosispatients for the experiment.Our data sug-gested that the accordance rates of bothmethods were 83.3％. Gas chromatographyis a simple,rapid and accurate method fordetecting drug-resistance. The resultscan be obtained twenty days earlier thanby the routine method.更多还原
