[Tuberculosis caused by Mycobacterium bovis: apropos of 2 cases].

Infection by Mycobacterium bovis is currently a rare form of tuberculosis in developed countries, being its incidence lower than 1%. Its main mechanism of transmission is through the ingestion of contaminated milk. In this paper, two cases of tuberculosis by Mycobacterium bovis are described, one of lymphatic location by endogenous reactivation and another of pulmonary location, probably by a primary infection acquired through the inhalation route. We stress the risk of transmission of the disease through the respiratory route from infected animals and by person to person contagion.
