وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...

Herpes simplex virus type 1 strains ANG and KOS lack neuroinvasiveness when inoculated on the footpads of mice, and because the strains are able to complement each other, the genes associated with this phenotype differ. In this study, we used marker rescue techniques to show that at least two genes cloned from ANG are required to restore neuroinvasiveness to KOS. One of the two fragments requir...

As causative agents of duck viral hepatitis, duck hepatitis A virus type 1 (DHAV-1) and type 3 (DHAV-3) causes significant economic losses in the duck industry. However, a licensed commercial vaccine that simultaneously controls both pathogens is currently unavailable. Here, we generated duck enteritis virus recombinants (rC-KCE-2VP1) containing both VP1 from DHAV-1 (VP1/DHAV-1) and VP1 from DH...

Herpes simplex viruses (HSVs) are frequent human pathogens and the ability to engineer these viruses underpins much research into their biology and pathogenesis. Often the ultimate aim is to produce a virus that has the desired phenotypic change and no additional alterations in characteristics. This requires methods that minimally disrupt the genome and, for insertions of foreign DNA, sites mus...

هدف: از چالش­های عمده بشریت افزایش افسردگی و اختلال عملکرد جنسی ناشی داروهای ضدافسردگی است. با توجه به نقش سلول­های سرتولی در اسپرماتوژنز، پژوهش حاضر، اثر داروی دولوکستین را بر زنده­مانی، آپوپتوزیس بیان ژن­های Bax و­ (Connexin 43) Cx43 بررسی کرده مواد روش‌‌ها: TM4 محیط DMEM/F12 حاوی %5/2 FBS، 5% سرم اسب %1 پنی سیلین-استرپتومایسین کشت شدند. دوزهای 30،60، 15، 5/7، 75/3 میکرو­گرم/ میلی­لیتر زمان­ه...

Fibropapillomatosis (FP) of marine turtles is an emerging neoplastic disease associated with infection by a novel turtle herpesvirus, fibropapilloma-associated turtle herpesvirus (FPTHV). This report presents 23 kb of the genome of an FPTHV infecting a Hawaiian green turtle (Chelonia mydas). By sequence homology, the open reading frames in this contig correspond to herpes simplex virus genes UL...

Members of the viral subfamily Alphaherpesvirinae establish latency from which they can be reactivated. Bovine herpesvirus 1 causes infectious bovine rhinotracheitis and infectious pustular vulvovaginitis in cattle, as well as abortion and weak calves. Serological evidence of alphaherpesvirus infection has been reported for wild and semidomesticated reindeer (Rangifer tarandus tarandus) in Norw...
