[ 8 ] - Prevalence of avian metapneumovirus subtype B in live bird market in‎ Gilan province, Iran

Avianmetapneumovirus (aMPV), also known as avian pneumovirus or turkey rhinotracheitis virus, is the causative agent of turkey rhinotracheitis and swollen head syndrome in chickens. Four aMPV subgroups (A-D) have been reported previously based on their genetic and antigenic differences. Evidence suggests that the live bird markets (LBMs) play an important role in the epidemiology of the avian v...

During December and February 2010, two red deer were died in Semeskandeh sanctuary in Mazandaran province. Moreover, five live deer from mentioned area were treated by Ivermectin and collected feces of these animals were used for assessment helminthes infection by parasitological met...

[ 12 ] - مقایسه دو روش نات اصلاح شده (Modified Knott test) و سرم‌شناسی(ELISA antigen test) در تشخیص دیروفیلاریا ایمیتیس

  خلاصه:   دیروفیلاریا ایمیتیس ( Dirofilaria immitis ) عامل بیماری فیلاریوز قلبی عروقی در سگ و انسان است. این بیماری انتشار جهانی دارد ولی آلودگی در نواحی معتدل، گرمسیری و نیمه گرمسیری به صورت بومی دیده می­شود. آلودگی به کرم قلب را می­توان با آزمایش خون و نشان دادن میکروفیلرهای در گردش و یا پادگن­های کرم بالغ تشخیص داد. به منظور ارزیابی کارایی روش­های متداول در تشخیص دیروفیلاریوز، در این مطالعه...
