First report of Nocardia fusca isolated in humans.

Nocardia fusca was first described in 1983; however, to date, no report of human infection has been done. In this work, we report the first case of N. fusca isolation during an episode of acute exacerbation in a patient with chronic obstructive pulmonary disease. The extent of the role of N. fusca as human pathogen still has to be determined.
