Methods: From June 2009 to July 2013, 112 brain samples of aborted ovine fetuses were collected and examined to detect T.gondii DNA by nested- PCR. The association the frequency of T.gondii infection with age and geographical location of aborted fetuses were also studied. Results: The results showed that 18 (16.07%) of brain samples of aborted fetuses were Toxoplasm positive in PCR reaction . The frequency of T.gondii in the age group ≥120 day was more than other age groups of infected aborted fetuses (P<0.05) . All the infected fetuses belonged the sheep flocks in the northern part of province.
