Mycobacterium szulgai identification by hsp65 gene sequencing in an HIV-positive patient with non-Hodgkin's lymphoma.

Mycobacterium szulgai, described for the first time in 1972, is a rare human pathogen that mainly causes pulmonary non-tubercular mycobacteriosis. We report its isolation and identification from a bronchoalveolar lavage specimen by hsp65 gene sequencing analysis in an HIV-positive patient with non-Hodgkin's lymphoma.
