چکیده مقاله :

هرپس ویروس ها خسارات اقتصادی زیادی را به صنعت پرورش اسب در سراسر دنیا وارد می کنند. هرپس ویروس های 1 و 4 اسبی موجب درگیری تنفسی، سقط، مرگ و میر نوزادان و نیز در موارد نادر، باعث ادم اندام های حرکتی و میلوانسفالوپاتی در اسب های حساس می شوند. هدف از انجام مطالعه حاضر، ارزیابی فراوانی آلودگی سرمی با هرپس ویروس های 1 و 4 اسبی در اسب های باشگاهی شهرستان ارومیه با احتساب سن، جنس، نژاد و نشانه های بالینی بود. بدین منظور نمونه‌های سرمی مربوط به 51 رأس اسب، به روش الایزای غیرمستقیم برای ردیابی پادتن های اختصاصی ضد هرپس ویروس های 1 و 4 اسبی آزمایش شده و داده های حاصله با استفاده از آزمون های کای دو، پیرسون، دقیق فیشر و رگرسیون لجستیک، مورد تجزیه و تحلیل آماری قرار گرفتند. تعداد 9 نمونه (65/17 درصد) (فاصله اطمینان 95 درصد: 0/28-2/7) واجد واکنش مثبت سرمی برای پادتن های اختصاصی هرپس ویروس 1 و 4 اسبی بودند و فراوانی سرمی مذکور، تحت تاثیر سن (593/0=p)، جنس (651/0=p)، نژاد (874/0=p) و نشانه های بالینی (824/0=p) قرار نداشت. البته در آنالیز رگرسیون مشخص شد که شانس آلودگی بر اساس سن با کاهش هر 4 سال، 51/1 درصد افزایش می‌یابد و در اسب های ماده، 549/1 درصد بیشتر از اسب های نر می باشد. همچنین سن اسب ها 449/0 درصد، جنسیت اسب ها 437/0 درصد و نژاد اسب ها 217/0 درصد از تغییرات آلودگی را توجیه می‌کند. جمع بندی نهائی نتایج نشان از مواجهه نسبتاً بالای تیپ های 1 و 4 هرپس ویروس اسبی با جمعیت اسب های باشگاهی شهر ارومیه دارد.

چکیده انگلیسی:

Herpesviruses can cause significant economic losses to the equine industry worldwide. Equine herpes virus type 1 (EHV-1) and type 4 (EHV-4) cause respiratory signs, abortion, neonatal death and in some cases distal limb edema and myeloencephalopathy in susceptible horses. The aim of this study was to determine the seroprevalence of EHV-1 and EHV-4 infection in club horses of Urmia in relation to age, gender, breed and clinical signs. Sera from 51 horses were tested by indirect enzyme linked immunosorbent assay (iELISA) for detection of specific antibodies against EHV-1 and EHV-4 and data were analyzed by chi-squared, fisher’s exact and logistic regression tests. A total of 9 samples (17.65%) (95% CI: 7.2-28.0) were found to be positive for specific antibodies of EHV-1 and EHV-4. Seropositivity was not affected by age (p=0.593), sex (p=0.651), breed (p=0.874) and clinical signs (p=0.824). Although in regression analysis it was found that odds of infection based on age was increased by 1.51% for every 4 year decrease in age and odds of infection was 1.549% more in females compared with males. Also age, gender and breed of horses explains 0.449, 0.437 and 0.217% of infection rate fluctuations, respectively. In conclusion, the results indicate relatively high exposure of equine herpes virus types 1 and 4 in club horses of Urmia.
