An epidemiological survey of setaria in the abdominal cavities of Iranian sistani and brahman cattle in the southeastern of iran.
AbstractBackground: In this experiment, abdominal cavity of 518 Iranian Sistani cattle and 498 Brahman cattle were inspected for the presence of Setaria spp. from April 2012 - May 2013.Methods: The species were determined by microscopic examination of the mor-phological characteristics of the anterior and posterior parts of the parasites and authentic guidelines.Results: The overall prevalence of Setaria spp. was 28.6% and 36.5%, respectively and this difference was significant (P<0.05). Out of 148 Sistani cattle which were infected with Setaria, 51(34.4%) were infected with S. digitata, 31 (20.9%) were in-fected with S. labiatopapillosa, 65 (43.9%) showed mixed infection of S. digitata and S. labiatopapillosa and one case (0.6%) was infected with mixed infection of S. labiato-papillosa, S. digitata and S. marshalli. These values were 87 (47.8%), 27 (14.8%), 67 (36.8%) and 1 (0.5%) for 182 infected Brahaman cows, respectively. The propor-tion of infected cattle in spring and summer was greater than cooler season (au-tumn and winter) significantly (P<0.001). The prevalence of infection with Setaria in 2-3 years old Sistatni cattle (42.2 %) was greater than other age categories (P<0.05). Furthermore, the infection rate between males (25.5%) and females (37.3%) Iranian Sistani cattle showed significant difference (P =0.009).Conclusion: It is important to point out the presence of cerebrospinal setariosis, namely in sheep, goats and horses in the investigated area.
