An investigation of sheep toxoplasmosis in Basrah Province / Iraq
The objective of this study was to investigate Toxoplasma gondii antibodies among sheep in different regions of Basrah province (including Al-Mdayna, Shatt Al-Arab, Al-Basrah, Al-Zubayr, and Abu Al-Khasib). The study was started in Oct. 2008 and was finished in May 2009, using latex agglutination test (LAT) and indirect enzyme linked immunosorbent assay (ELISA) IgG, 309 adult sheep were randomly selected from 15 herds among different ages and both sexes and used in this study, including 62 pregnant ewes, 185 non-pregnant ewes, 14 aborted ewes, and 48 rams. Results showed, that 60.84% were seropositive by LAT, whereas 51.11% were seropositive by ELISA IgG test, among animals used in this study, results detected that 79.03% pregnant ewes (highest value), 56.75% nonpregnant ewes,71.40% aborted ewes and 50% Rams (lowest value) were seropositive by LAT, whereas 56.52% pregnant ewes, 51.11% non-pregnant ewes, 83.33% aborted ewes (highest value), and 31.25% Rams (lowest value) were seropositive by indirect ELISA IgG. Moreover, among regions of Basrah province, the details of percentage of T.gondii antibodies were 54.54% in AL-Basrah , 71.43% in Abu Al-Khasib (highest value), 57.35% in Al- Mdayna, 47.83% in Shatt Al-Arab (lowest value), and 67.16% in Al-Zubayr by LAT, whereas 63.64% in AL-Basrah (highest value), 22.73% in Abu Al-Khasib (lowest value), 57.89% in Al-Mdayna, 50% in Shatt Al-Arab and 61.90% in Al-Zubayr by indirect ELISA test. Although the difference observed in the percentage of Toxoplasma gondii antibodies among different regions of Basrah, there was no significant difference P>0.05 detected LAT, whereas in the indirect ELISA IgG test there was significant difference P<0.05. Ewes showed high percentages 62.83%, 55.40% of toxoplasmosis than rams 50 %, 31.25% by LAT and ELISA test respectively. The highest titer was 1/4 28.57% were detected in pregnant ewes and lowest titers were 1/2, 1/8, and 1/256 0.0% were detected in aborted ewes and in rams
