Non-tuberculous mycobacterias (NTM) are important pathogens responsible for a broad spectrum of diseases in humans. Although exposure is widespread since they are distributed in the environment, the development of the disease is rare. It will depend on the specific species, their virulence (only 50 have been found to cause disease), and the host’s immune response. M Mycobacterium Malmoense is a NTM first reported in 1977 at Malmö, Sweden, based on four cases of lung infections. After these, other infections have been reported mainly involving the respiratory tract. Extrapulmonary infections are limited to cervical adenitis, and rarely to tenosynovitis and disseminated disease. We are hence reporting, to our knowledge, the first case of M. malmoense as the cause of bacterial endocarditis in the world.
