An Australian isolate of Mycobacterium shimoidei.

A case of Mycobacterium shimoidei in a 75 year old man is reported. He had been a smoker, with a past history of bullous emphysema and a lung abscess. He had a 12 month history of weight loss, night sweats, with increased cough and sputum, and progressive opacification of the left apex with cavity formation. Sputum repeatedly grew M. shimoidei, identification of which was confirmed with high-pressure liquid chromatography (HPLC). He was treated for 45 days with three drugs to which the organism was sensitive, but failed to respond. His death was attributed to mycobacterial infection.
