Abstract
<i>Mycobacterium mageritense</i>Pulmonary Disease in Patient with Compromised Immune System
Highlights
We describe a case of M. mageritense pneumonia in an immunocompromised patient
Five months earlier, organizing pneumonia was diagnosed in the patient by computed tomography– guided lung biopsy of a pleura-based mass; special stains and cultures on tissue for acid-fast bacilli (AFB), other bacteria, and fungi were negative
Cultures of lung tissue and pleural fluid grew mycobacteria initially identified as M. fortuitum group but subsequently identified as M. mageritense by PCR followed by restriction enzyme analysis of the 65kDa heat-shock protein [6]
Summary
It was first isolated in Spain in 1987, described as a new species in 1997 by Domenech et al [1], and first described and associated with disease in the United States in 2002 [2]. A study from Japan in 2007 reported recovery of M. mageritense from the sputum of a woman with noncaseating granulomas by transbronchial biopsy who improved without therapy [5]. We describe a case of M. mageritense pneumonia in an immunocompromised patient.
