Abstract

Mycolic acids extracted from saponified mycobacterial cells were examined as p-bromophenacyl esters by high-performance liquid chromatography (HPLC). Standard HPLC patterns were developed for species of Mycobacterium by examination of strains from culture collections and other well-characterized isolates. Relative retention times of peaks and peak height comparisons were used to develop a differentiation scheme that was 98% accurate for the species examined. A rapid, cost-effective HPLC method which offers an alternative approach to the identification of mycobacteria is described.

摘要

通过高效液相色谱法(HPLC)对从皂化分枝杆菌细胞中提取的霉菌酸进行对溴苯甲酰酯检测。通过检测来自培养物保藏中心的菌株和其他特征明确的分离株,建立了分枝杆菌属各菌种的标准HPLC图谱。利用峰的相对保留时间和峰高比较,制定了一种鉴别方案,对所检测的菌种鉴别准确率达98%。本文描述了一种快速、经济高效的HPLC方法,该方法为分枝杆菌的鉴定提供了另一种途径。
