|Abstract:||Despite of four decades of effective chemotherapy, tuberculosis has re-emerged as one of the leading causes of death. Prevention and control of tuberculosis got a great setback by the appearance of multidrug resistant strains of M. tuberculosis. New antibiotic regiments are needed for the treatment of multidrug resistant tuberculosis. -Lactam antibiotics that inhibit trans peptidase reactions and prevent cell wall assembly in bacteria are the most widely used antimicrobial agents. However, most of the mycobacteria are naturally resistant to -lactams,presumably because of their extremely hydrophobic cell wall, presence of periplamsic penicillin binding proteins (PPHS) and most importantly the presence of an active -lactamase.This paper details the various studies on -lactamasesof Mycobacterium and highlights the importance of -lactamases,in future, for developing an effective drug combination comprising a -lactamantibiotic in combination with -lactamaseinhibitors.|
