Technical Abstract: Sheep are important to the economy of many countries. Sheep are commonly infected with the protozoan parasite, Toxoplasma gondii. This parasite causes early embryonic death and resorption, fetal death and mummification, abortion, stillbirth, and neonatal death, largely dependent on the stage of pregnancy at which the ewe becomes infected. Until recently, the prevailing view was that most sheep acquire T. gondii infection after birth, and less than 4% of persistently infected sheep transmit it in the next generation. Recent studies from a group of researchers in England proposed that repeat ovine transmission of T. gondii maybe more common than previously believed. These findings have important bearing on sheep management. In the present paper, information on prevalence, transmission, and control of ovine toxoplasmosis is reviewed.
