Effect of peroxidase on the development of experimental leprosy in mice after intraplantar infection.

Lyophilized horseradish peroxidase (activity 100 U/mg) administered per os in a dose of 100-200 mg/kg fodder enhanced bactericidal activity of phagocytes in mice experimentally infected with Mycobacterium leprae, which manifested in suppression of M. leprae growth in comparison with untreated controls.
