چکیده

نئوسپورا کانینوم انگل داخل سلولی اجباری از شاخه آپی‌کمپلکسا بوده و باعث سقط جنین در گاو و فلج عصبی عضلانی در سگ می‌گردد. با توجه به ضررهای اقتصادی وارده به صنعت دامپروری در اثر سقط جنین و کاهش تولید شیر ناشی از نئوسپورا کانینوم، فراوانی این تک یاخته در گاوهای شیری منطقه شهریار مورد ارزیابی قرار گرفت . با توجه به پراکندگی دامی 150 نمونه شیرخام از 5 دامداری گاو شیری از 4 منطقه شهریار جمع آوری و با روش الایزای غیر مستقیم از لحاظ وجود آنتی بادی ضد نئوسپورا کانینوم مورد ارزیابی قرار گرفتند. از مجموع 150 نمونه، 22% از لحاظ وجود آنتی بادی ضد نئوسپورا کانینوم مثبت برآورد گردید. با استفاده از آزمون مجذور کای بیشترین میزان شیوع در گاوهای بالاتر از 4 سال سن مشاهده گردید (۰۳۹/۰=P-value)آزمون الایزای غیر مستقیم بکار رفته در شیر بنظر می رسد مفید و مقرون به صرفه برای نظارت بر برنامه های استراتژی کنترل نئوسپورا کانینوم در مزارع پرورش گاو شیری باشد.

چکیده [English]

Neospora caninum is an obligate intracellular parasite in the Apicomplexa phylum. The parasite causes abortion in cattle and Neuromascular paralysis in dog. Given the economic losses incurred by abortion caused by Neospora caninum and reduced milk production, in this study the frequncy of Neospora was evaluated by ELISA in the Shahriyar area. 150 samples of raw milk of 5 dairy cattle herds collected and tested for the detection of antibodies against Neospora caninum by ELISA. 22% of the samples were positive for the presence of antibodies against Neospora. The highest prevalence was observed in cows older than 4 years of age (P-value =0.039). The indirect ELISA used in milk seems to be a useful for epidemiological surveys, and to increase the level of control strategy of Nespora caninum in dairy cattle farms.
