[ 1 ] - Titration of the Iranian White Spot Virus isolate, on Crayfish Astacus leptodactylus and Penaeus semisulcatus
White Spot Virus (WSV) is currently the most serious viral pathogen of shrimp worldwide it causes mortality up to 100% within 7-10 days in commercial shrimp farms. Infected Indian white shrimp Fenneropenaeus indicus samples were collected from Guatr shrimp site in Sistan and Baluchestan province in south of Iran and WSV infection was confirmed by Nested PCR. WSV was isolated from infected shr...
[ 2 ] - Immunization of Litopenaeus vannamei shrimp against white spot syndrome virus (WSSV) by gamma-irradiated WSSV plus Vibrio paraheomolyticus
Introduction: White spot syndrome virus (WSSV) is one of the most deadly infectious pathogens of the shrimp culture industry. Neither effective vaccines nor efficient treatments are currently available for this disease. Vibrio species are well known dominant bacterial pathogens in the shrimp ponds. As facultative pathogenic bacteria, it is possible that Vibrio spp. along with WSSV to co-infect ...
[ 3 ] - واکسن پرتوتابی‌شده بیماری ویروسی تب برفکی تایپ آسیا-1 و ارزیابی پاسخ ایمنی در خوکچه هندی
مقدمه: بیماری تب برفکی یکی از بیماری‌های حاد ویروسی است که موجب بیماری گونه‌های مختلف حیوانات زوج‌سم و وحوش می‌شود. ویروس عامل بیماری به خانواده پیکورناویریده و جنس آفتوویروس تعلق دارد. هدف پژوهش حاضر، ساخت رادیوواکسن بیماری تب برفکی تایپ آسیا-1 با استفاده از پرتوی گاما و ارزیابی پاسخ‌های ایمنی هومورال و سلولی در خوکچه‌های هندی واکسینه‌شده است. مواد و روشها: ابتدا ویروس تب برفکی تایپ آسیا-1 ت...

[ 5 ] - Recombinant VP1 Protein of FMD Virus Type O/IRN/2010 as an Immunogenic Peptide Expression System
Foot and Mouth Disease (FMD) is highly contagious disease among cloven-hoofed animals. FMD virus has structural and non-structural proteins. Vp1 is the most immunogenic structural peptides of FMD virus, applied for major vaccine studies. Objective: Construction of Pet28-VP1 cassette for FMD virus type O/IRN/2010 and expression VP1 peptide as the most immunogenic antigen was the aim of this stud...
[ 6 ] - Development of an ELISA Test for Detection of Anti FMD Virus Type A87/IRN Antibody Using Irradiated Antigen
Background and Aims: The aim of this study was application of gamma irradiated FMDV antigen for liquid phase blocking sandwich ELISA (B-ELISA) to quantify guinea pig anti FMDV type A87/IRN antibody. Methods: FMDV type A87/IRN was propagated to a titer of 107.5/ml TCID50 and then irradiated by gamma irradiator. The irradiated 146 S antigen was purified by sucrose gradient centrifugation after in...
[ 7 ] - استفاده از پرتوتابی گاما برای حذف آلودگی باکتریایی آغوز گاو
In order to colostrum pasteurization and creating of dose-response curve for Escherichia coli and Staphylococcus aurous, the colostrum of cow was gamma irradiated at doses of 0, 0.5, 1 and 2 KGy. Chemical composition, true protein, electrophoretic pattern of proteins, lactose content, peroxide level and pH of colostrums samples before and after of irradiation were determinate. The obtained...
