BACKGROUND
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 morphological 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 infected 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. labiatopapillosa, 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 proportion of infected cattle in spring and summer was greater than cooler season (autumn 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).
CONCLUSIONS
It is important to point out the presence of cerebrospinal setariosis, namely in sheep, goats and horses in the investigated area.
