title: A species of Sarcocystis using owls as definitive hosts.
abstract: Sporulated oocysts found in the intestines of a Masked Owl (Tyto novaehollandiae) and a Barn Owl (T. alba) produced sarcocysts in mice. Schizonts were found in the livers of 3 mice that died at 7-8 days after dosing. Neither sarcocysts nor schizonts were found in chickens dosed with oocysts from a Masked Owl.
