چکیده

سارکوسیستیس تک‌یاخته انگلی درون‌سلولی اجباری است که می‌تواند موجب اختلالات گوارشی در گوسفندان و خسارات هنگفت مالی در صنعت دامداری گردد. این مطالعه با هدف تعیین میزان شیوع عفونت سارکوسیستیس در گوسفندان کشتاری در کشتارگاه شهرستان خوی انجام شد. برای این منظور لاشه 204 رأس از گوسفندان کشتاری از نظر وجود ماکروکیست با مشاهده چشمی و سپس به‌روش میکروسکوپی مورد بررسی قرار گرفت. بر اساس نتایج حاصله 12 رأس (88/5 درصد) از لاشه‌ها به ماکروکیست آلوده بود. در بررسی میکروسکوپی 87 رأس (65/42 درصد) از گوسفندان آلوده تشخیص داده شدند. تحلیل داده‌ها بیانگر وجود اختلاف معنی‌دار آماری بین میزان آلودگی در رده‌های سنی مختلف بود و میزان آلودگی با افزایش سن بیشتر می‌شد (05/0p < )، در حالی‌که میزان آلودگی مستقل از جنس بود. همچنین اختلاف آماری معنی‌داری بین میزان آلودگی در عضلات مختلف وجود داشت (05/0 p < ) و بیشترین میکروکیست در عضلات اسکلتی (80/90 درصد) و کمترین میکروسیست در عضلات قلب (88/29 درصد) مشاهده شد. این مطالعه اهمیت و ضرورت ارزیابی میکروسکوپی را در تشخیص آلودگی ساکوسیستیس در لاشه‌های گوسفندی نشان داد.

چکیده [English]

Sarcocystis is an obligatory intracellular protozoan parasite that can cause digestive disorders in infected patients. This study aimed to determine the incidence of Sarcocystis infection in slaughtered sheep of the Khoy abattoir, Iran. For this, 204 sheep carcasses were examined by visual observation and then further analyzed by digestion method. Based on the results, 5.88% of the studied carcasses were diagnosed with macrocytic observation. In the microscopic examination, 42.65% of the cases were found positive. Data analysis showed a statistically significant difference between contamination rate in different age groups. The occurrence rate increased with age (P < 0.05), while the intensity of infection was independent of the gender. There was also a statistically significant difference between the contamination rate among different muscles (p <0.05). In other words, the highest microcyst contamination observed in skeletal muscles (90.80%). Meanwhile, the lowest microcyst contamination was observed in the heart muscle (29.88%). This study showed the necessity of microscopic observation of the Sarcocystis contamination in the sheep carcasses.
