The Mono Mac 6 (MM6) human monocytic cell line was evaluated with the established J774 murine macrophage cell line to ascertain its effectiveness in determining the intracellular activities of antimycobacterial drugs. Cells were infected with Mycobacterium tuberculosis H37Ra and treated with drug concentrations corresponding to the MICs, as well as to threefold higher than and threefold less than the MICs. Changes in CFU were compared after 7 days to determine significant differences between treated and nontreated groups. The results suggest that MM6 will make a useful model for testing the intracellular activities of antituberculosis drugs.
使用已建立的J774小鼠巨噬细胞系对Mono Mac 6(MM6)人单核细胞系进行评估,以确定其在测定抗分枝杆菌药物细胞内活性方面的有效性。细胞用结核分枝杆菌H37Ra感染,并用相当于最低抑菌浓度(MIC)的药物浓度以及比MIC高三倍和低三倍的药物浓度进行处理。7天后比较菌落形成单位(CFU)的变化,以确定处理组和未处理组之间的显著差异。结果表明,MM6将成为测试抗结核药物细胞内活性的有用模型。
