- Abstract
Sarcocystosis is a zoonotic parasitic disease caused by cyst forming coccidian protozoa of the genus Sarcocystis species. These parasites require two hosts life cycle including herbivorous as intermediate host and carnivorous as definitive host. Total of 1100 slaughtered sheep, goats and cattle divided into three age groups were macroscopically examined for the presence of macrosarcocystis, as well as 70 stray dogs and cats existed around the slaughter houses and butcher places were microscopically examined for the occurrence of oocysts & sporocysts of this protozoan in the feces. The overall frequency rate of macrosarcocystis in the intermediate hosts was 17.81% (196/1100). The infection rate in sheep was 22.4% (112/500) and in goats was 16.8% (84/500), while no macrocystis (0/100) was observed in cattle. Moreover, the percentage rate of the parasite in male and female of sheep (7.5% & 41%) and goats (6.25% & 38%) in age group 3-4 years was found higher than the other groups. The parasitic incidence in esophagus, abdominal muscle, and diaphragm of the ruminants was 17.72%, 8.90% and 5.09%. The largest measurement size of bradyzoites (24.02±1.30 µm x 8.13±0.35 µm) was found in the abdominal cysts. Furthermore, the overall distribution rate of sporocysts in dogs and cats was 25.71%. The infection rate in dogs (28%) was higher than in cats (20%). Statistically, no significant differences (P> 0.05) were observed in the frequency and distribution rate of the infection among the intermediate and definitive hosts, while significant differences (P< 0.05) revealed among the age groups of the ruminants.
