title: Unidentified Toxoplasma-like tissue cysts in the brains of three cats.
abstract: Tissue cysts of an unidentified Toxoplasma-like parasite were found in three of 103 cats that were diagnosed histologically with toxoplasmosis-like illness at the Angell Memorial Animal Hospital, Boston, MA, between 1952 and 1991. Tissue cysts in these three cats were confined to the brain and two cats had concurrent lymphoid disorders. The tissue cysts of the unidentified parasite were about twice the size of Toxoplasma gondii tissue cysts.
