摘要: 目的建立并评价微孔板Alamar Blue和MTT试验方法用于结核分枝杆菌药物最低抑菌浓度的测定。方法应用Alamar Blue和MTT显色法对12种抗结核药物的结核分枝杆菌H37RV的最低抑菌浓度进行测定,并与传统的试管二倍稀释法进行比较。结果Alamar Blue和MTT试验分别在6和8 d报告结果,Alamar blue法与试管法相比较,一致率是91.7%(11/12);MTT法与试管法相比较一致率是75%(9/12),具有较好的一致性。结论Alamar Blue和MTT方法测定药物对结核分枝杆菌的MIC具有快速、操作简便等特点,适用于新抗结核化合物的大量快速筛选。

Abstract: Objective To set up and assess Alamar blue and MTT assays for determining the MIC of the anti-tuberculosis drugs to Mycobacterium tuberculosis.Methods MIC of 12 anti-tuberculosis agents to Mycobacterium tuberculosis H37RV were determined by Alamar Blue assays and MTT,and compared to the conventional two folds dilutions.Results For Alamar blue assays and MTT,the time for obtaining Results were 6 days and 8 days,respectively.MICs determined by MTT or Alamar blue assay were highly correlated with those determined in the two folds dilutions.Conclusion Alamar blue and MTT assays are sensitive,rapid,inexpensive,and promising new alternative Methods for performing rapid high-throughout screening of compounds against Mycobacterium tuberculosis.
