A small outbreak of fatal toxoplasmosis is described in 6 kakariki (Cyanoramphus spp.) in an aviary in Australia. Toxoplasma gondii-like tachyzoites were found associated with necrosis in intestine, spleen, liver, and lungs. Tachyzoites reacted positively with T. gondii-specific polyclonal antibodies. This is the first report of toxoplasmosis in kakariki.
