Background: Ochroconis gallopava is a neurotropic dematiaceous mold that causes respiratory and central nervous system (CNS) infection in domestic poultry and in immunocompromised patients. We recently treated 3 solid organ transplant (SOT) recipients for pulmonary Ochroconis infections with successful outcome, prompting us to review the literature on this unique pathogen.
Methods: We reviewed all published cases of O. gallopava infections in SOT recipients and analyzed the impact of CNS infection on the outcome.
Results: In addition to the 3 new cases reported here, 9 published cases of Ochroconis infection were analyzed. The disease involved the lungs only in 5/12 (42%) of patients, brain in 6/12 (50%) patients, and lung and skin in 1 patient. Survival was significantly reduced with brain infection (33% vs. 100%; P<0.03; Fisher's exact test).
Conclusions: O. gallopava may infect SOT recipients with a particular tropism for the CNS. Early recognition of O. gallopava pulmonary infection is important, as the prognosis is excellent before dissemination to the brain.
