A rare pulmonary infection caused by Arthrographis kalrae.

Arthrographis kalrae is a rare isolate in clinical specimens. Only ten cases of infection with this species have been described so far. To our knowledge, we report the first case of a pulmonary infection caused by A. kalrae in a patient with a past history of stage IIA Hodgkin's lymphoma and demonstrate that this organism can act as an opportunistic human pathogen.
