OCULAR TOXOPLASMOSIS IN WALLABIES (MACROPUS-RUFOGRISEUS)

We initiated a pathologic investigation of ocular disease in wallabies. Of 21 animals examined, the eyes were investigated histologically in 11; in four of these animals the brains were also available for section and the sera were investigated in three. In ten animals only sera were received. Histologic studies showed bilateral or unilateral cataract in five animals. Eight animals, with or without cataracts, showed various degrees of keratitis, uveitis, choroidoretinitis, or endophthalmitis. In three animals Toxoplasma cysts were found within the retina or brain, or both. Of the 13 cases examined serologically 11 were positive for toxoplasmosis; three reached high titers. © 1979.
