Mycobacterium Chlorophenolicum Isolation in Sirolimus-Associated Pneumonitis

Mycobacterium chlorophenolicum is a nontuberculous mycobacterium that has previously been characterized as nonpathogenic. We describe a 44 year-old patient with a history of deceased donor renal transplant on sirolimus who was found to meet criteria for both sirolimus-associated pneumonitis and secondary infection with Mycobacterium chlorophenolicum. In addition to describing a new infection with a generally nonpathogenic organism, we believe this case could generate new hypotheses regarding nontuberculous mycobacteria and the pathogenesis of sirolimus-associated pneumonitis.
