Toxoplasmose e neosporose ovina: estudo da arte.

Abstract

This study had the objective to make a brief review on sheep toxoplasmosis and neosporosis. Toxoplasma gondii causes an infectiousparasitic acute or sub-acute disease characterized by a polimorph symptomatology, sometimes showing general, respiratory, neurologic or reproductive symptoms, including abortion. This disease was first reported in a rodent (Ctenodactylus gondi) in South Africa. In sheep it was first reported in 19942 by Olafson & Monlux in USA. Neospora caninum is an obligatory intracellular parasite very similar to Toxoplasma gondii, and confounded with this other parasit until 1988. The ethiological agent was initially described and characterized in dogs, and subsequently in other species, including cattle. Prevalence level of 0.45% in sheep was observed in one of the few studies on naturally infested animals, when a newborn lamb died within seven days showing neurological symptomatology. Showing aspects as historical, ethiological agent, life cycle, host, transmission, control and prevention
