LDH isoenzyme as a tool for the identification of mycobacteria.

ABSTRACT

Using Polyacrylamide gel electrophoretic technique, the lactate dehydrogenase (LDH) isoenzyme patterns have been studied in four slow growing mycobacteria viz. Mycobacterium tuberculosis, M. avium, M. microti, and M. bovis and four rapid growing mycobacteria viz. M. Fortuitum, M. parafortuitum, M. thermoresistible and M. diernhoferi. Each mycobacterial species exhibited distinct isoenzyme pattern for LDH.
