[Coinfection of Mycobacterium malmoense and Mycobacterium tuberculosis in a patient with acquired inmune deficiency syndrome].

A case is presented of coinfection with Mycobacterium malmoense and Mycobacterium tuberculosis in a Cuban patient with AIDS which produced respiratory and liver disease respectively. Cultures done from sputum samples showed the presence of a non-pigmented, slow growing mycobacterial strain belonging to Runyon group III and identified as Mycobacterium malmoense. From cultures of liver tissue removed laparoscopically, a strain was isolated and subsequently identified as Mycobacterium tuberculosis. Anatomapathologic examination confirmed the diagnosis of tuberculosis, the patient received specific treatment and had a favorable clinical course. This report of a rare case of coinfection of Mycobacterium describes the first report of hepatic tuberculosis in a patient with AIDS in Cuba.
