Studies on Sarcocystis species IV: Aspecies infecting dogs and goats; development in goats

Abstract

The development of a dog:goat species of Sarcocystis was studied experimentally in goats. Schizogony in vascular endothelium at 18 and 19 days after infection was associated with-pyrexia, anaemia, anorexia, depression and death. Clinical signswere dose-related and doses of 6 × 10⁵ or more sporocysts were fatal. Muscle invasion took place before 34 days. At 129 days, sarcocysts were infective for dogs and the life cycle was completed. Sporocysts of this dog:goat species were not infective for sheep.
