Pulmonary cavitary Mycobacterium kyorinense (M. kyorinense) infection in an Australian woman.

We describe a patient with pulmonary cavitary pneumonia from whom we serially isolated Mycobacterium kyorinense, an organism not previously reported in Australia, or associated with cavitary disease. We discuss the clinical presentation, the isolation of the organism on several specimens and initial management. M. kyorinense is a recently characterized species, which has previously only been described in Japan and Brazil [1].
