Toxoplasmosis in wallabies (Macropus rufogriseus and Macropus eugenii): blindness, treatment with atovaquone, and isolation of Toxoplasma gondii.

Australasian marsupials, especially wallabies, are highly susceptible to clinical toxoplasmosis. This paper describes the use of atovaquone for effective treatment of toxoplasmosis in 4 Bennett's wallabies (Macropus rufogriseus), along with the serology, isolation of Toxoplasma gondii, and genotyping of 3 T. gondii isolates from 5 captive wallabies. This is the first report of success in treating acute toxoplasmosis in wallabies, the first report of serology followed over a significant period of time, and the first report of isolation and genetic typing of T. gondii from wallabies in the United States.
