Abstract:
اجريت الدراسة الحاليه خلال الفترة من تشرين الاول 2013 الى ايار 2014 في محافظة واسط للكشف عن الاصابة T. gondii في الانسان والاغنام باستخدام الطرق الجزيئية والمصلية. تم جمع خمس مئة وثمانية عينات 500 عينه دم و8عينات من انسجه المشائم و305 عينه 300عينه دم و5ع | The present study was conducted during the period from October 2013 to May 2014 in Wasit province to detect the infection of T. gondii in women and sheep using Molecular and Serological methods.Five hundred and eight samples 500 blood samples and 8placenta and 305samples 300 blood samples and 5placenta were collected from both suspected women and sheep respectively. The sera samples were separated and examined by ELISA for human and Latex agglutination test for sheep to detect the infection with T. gondii serologically, then many blood and placental tissue samples (89 blood samples and 8 placental tissue samples for women, whereas 100 blood samples and 5 placental tissue samples for ewes) were subjected to polymerase chain reaction (PCR) technique to detect the infection molecularly.The Serological results showed that 17.8% of women were positive for the private screening ELISA detects toxoplasmosis (17 % with chronic infection and 0.8% with acute infection), it was noted that the highest rate of infection was in women who ranged in age between 20 - 29 years, reaching 19.9%, but with no significant difference (P>0.05) between the ages studied. On the other hand the rate of sheep infection by latex agglutination test with 2 - mercaptoethanol amounted to 33.33% (31.33% with chronic infection and 2% with acute infection) and most positive cases were among the ages which were equal to or more than 3 years (?3 years) with significant difference (P<0.05) between these ages. The present study indicated a lack of months effect on the distribution of parasite infection rates where these different months recorded relatively close rate ranged between 14.45% - 23.07% in women and 31.42% - 35.97% in sheep with no significant difference (P>0.05).Regarding to polymerase chain reaction test, a fragment of 399bp was amplified from B1 gene, the result showed that 6.74% and 4% of blood samples and 100% and 80% of placental tissue samples which taken from women and sheep respectively were positive to this test.
