Toxoplasma gondii-like organisms were seen in the heart, kidney, liver, lung, lymph node, spleen, small intestine, and stomach from 2 koalas that died suddenly in a fauna park in Sydney, Australia. Diagnosis was confirmed by immunohistochemical staining. This is the first confirmed report of toxoplasmosis in an arboreal marsupial.
