Catalase-peroxidase activity has no influence on virulence in a murine model of tuberculosis.

Abstract excerpt

The capacity to generate a chronic and persistent infection in the experimental murine model of tuberculosis induced aerogenically by a low-dose inoculum was determined in eight isoniazid-resistant clinical strains of Mycobacterium tuberculosis showing different catalase-peroxidase (C-P) activities.
