Profile analysis of mycolic acid ester patterns of Mycobacterium tuberculosis, Mycobacterium bovis, and Mycobacterium bovis bacillus Calmette-Gúerin (BCG) using high-performance liquid chromatography indicated that separation of BCG from M. tuberculosis and M. bovis by elution and relative retention times is possible. Mycolic acid patterns of BCG eluted from the column 0.5 min before M. tuberculosis or M. bovis, resulting in relative retention times for two peaks not seen in the pattern of M. tuberculosis or M. bovis. Identification was confirmed by phage typing, which has been the standard procedure for confirmation of BCG strains. These results showed that high-performance liquid chromatographic analysis of mycolic acid esters can be used in the mycobacterial reference laboratory for separation of BCG from M. tuberculosis and M. bovis.
使用高效液相色谱法对结核分枝杆菌、牛分枝杆菌和卡介苗(BCG)的分枝菌酸酯模式进行的剖析分析表明,通过洗脱和相对保留时间可以将卡介苗与结核分枝杆菌和牛分枝杆菌分离。卡介苗的分枝菌酸模式在结核分枝杆菌或牛分枝杆菌之前0.5分钟从柱中洗脱,导致在结核分枝杆菌或牛分枝杆菌模式中未出现的两个峰的相对保留时间。通过噬菌体分型确认了鉴定结果,噬菌体分型一直是确认卡介苗菌株的标准程序。这些结果表明,分枝菌酸酯的高效液相色谱分析可用于分枝杆菌参考实验室,以将卡介苗与结核分枝杆菌和牛分枝杆菌分离。
