Toxoplasmosis in three species of native and introduced Hawaiian birds

Toxoplasma gondii was found in endemic Hawaiian birds, including 2 nene geese (Nesochen sandvicensis), 1 red-footed booby (Sula sula), and an introduced bird, the Erckels francolin (Francolinus erckelii). All 4 birds died of disseminated toxoplasmosis; the parasite was found in sections of many organs, and the diagnosis was confirmed by immunohistochemical staining with anti-T. gondii-specific polyclonal antibodies. This is the first report of toxoplasmosis in these species of birds.
