Cetacean Morbillivirus and Toxoplasma gondii Co-infection in Mediterranean Monk Seal Pup, Italy.

A Mediterranean monk seal (Monachus monachus) pup from the southern Adriatic coast of Italy showed cetacean morbillivirus (CeMV) and disseminated Toxoplasma gondii co-infection, which probably resulted from CeMV-induced immunosuppression. These findings are of concern for the conservation of this critically endangered species.
