Study the relation of catalase enzyme production about the virulance of mycobacteria and brucella spp

Abstract

This study was investigated the virulence of mycobacterium spp and brucella spp and production of catalase enzyme Mycobacterium and Brucella spp. direct and indirect methods of catalase test were done. The result indicate the tightly relation between the virulent strains and actively production catalase enzyme showed a more potent (P≤0.05) in comparison with the a virulent strains which gave weak or negative reaction
