An epizootic of toxoplasmosis among captive black-faced kangaroos (Macropus fuliginosus melanops) is reported. Eight of 25 adult kangaroos had antibodies to Toxoplasma gondii. Serologic data indicated recent exposure to T. gondii in six kangaroos. Two kangaroos had high T. gondii antibody titers (greater than or equal to 16,384) in the modified agglutination test and their infants died when less than 7 months old. Toxoplasma gondii tachyzoites were found in several organs of one infant kangaroo (joey) that died at about 82 days of age and numerous cysts were seen in skeletal muscles of the other joey that died at about 7 months of age. Adult kangaroos had subclinical infections. The modified agglutination test and the dye test were more sensitive than the indirect hemagglutination and latex agglutination tests for the detection of T. gondii antibodies in kangaroo sera.
