[ 1 ] - The Characteristics of an Ovine Lymphoid Cell-Line sensitive to Vaccinal Infectious Bursal Disease Virus Strain

Infectious bursal disease (IBD), also known as Gumboro disease, is a globally well-known disease with a significant socio-economic effect. For control of IBD, several commercial egg- and cell-based vaccines are prepared. The cell-based IBD vaccines are significantly cost-effective; however, it is essential to confirm their safety and efficacy. The main cell line used to product the cell-based I...

[ 2 ] - S1 gene sequence analysis of infectious bronchitis virus vaccinal strains (H120 & H52) and their embryo-passaged derivatives

Avian infectious bronchitis is an acute and highly contagious disease that mainly causes respiratory symptoms in poultry. A number of serotypes and variants of the viral agent with poor cross-protection are the major problem to achieve desired immunity from vaccination. The S1 subunit of S glycoprotein (spike) is the major determinant of IBV so that a minor change in amino acid sequence of this...

[ 3 ] - Development and Cytogenetic Characterization of a Continuous Bovine Kidney Cell Line (IRKHBK) and Evaluation its Susceptibility to some Viruses

In this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in Iran. The cells were originating from two-day-old normal male calf of Holstein breed. The cell cultures were continuously passaged following complete proliferation of primary cells. The specific properties or characteristics of the cell were defined using cytogenet...

[ 4 ] - Monitoring virus harvesting time in embryonated chicken eggs inoculated with avian influenza H9N2 vaccine strain

Knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. The present study aimed to evaluate the best harvesting time of H9N2 avian influenza virus (AIV) vaccine strain inoculated in specific pathogen free (SPF) embryonated chicken eggs (ECE)s. For this purpose, 10-5 dilution of AIV (A/Chicken/Iran/99/H9N2) was inoculated into 336, 11-day old ECE...

[ 8 ] - القاء مرگ برنامه‌ریزی شده در سلول‌های اپی‌تلیوم تنفسی انسان آلوده شده با ویروس آنفلوانزا

Introduction: Avian influenza viruses are considered as a serious threat to human and animal health. An increase in expression of proinflammatory cytokines and type I IFN genes, as well as host cell death responses contribute to the pathogenesis of influenza infection. Hence, this study aimed to evaluate the growth dynamics of subacute avian influenza virus in human respiratory alveolar epithel...

[ 9 ] - بررسی کارآیی واکسن زنده تخفیف حدت یافته برونشیت عفونی سویه B08IR/ا793 ساخت موسسه رازی

از واکسن‌هایی که در حال حاضر برای کنترل بیماری برونشیت عفونی طیور مورد استفاده قرار می‌گیرد، واکسن حاوی سویه i793/Bمی‌باشد. بدنبال اثبات حضور ویروس i793/B در اکثر مرغداری‌های کشور واکسن زنده تخفیف حدت‌یافته برونشیت عفونی سویه i793/B081R، در موسسه رازی تولید شد. هدف از انجام این پروژه ارزیابی کارآیی واکسن i793/B081Rبر اساس پروتکل OIE با استفاده از ارزیابی فعالیت مژک‌های نای (Ciliary activity) پر...

[ 14 ] - Evaluating of Iran Razi Khedmati Bovine Kidney (IRKHBK) Cell Line for Isolation and ‎Propagation of Viruses

Abstract Background and Aims: To identify and isolation of viruses a susceptible cell is need which can be primary or line. The use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. IRKHBK cell line was originated from primary cells of bovine kidney by continuous passage. The aim of this study was to introduce the IRKHBK cell ...

[ 15 ] - ارزیابی سرولوژی واکسن زنده برونشیت عفونی طیور سویه 793B/08IR در جوجه‌های صنعتی گوشتی در شرایط کنترل شده

برونشیت عفونی بیماری بسیار مسری ویروسی ماکیان است و عامل مشکلات بهداشتی عمده صنعت طیور در بیشتر کشورهای دنیا به شمار می‌رود. بروز تغییرات پیوسته آنتی‌ژنی و ژنتیکی در ویروس برونشیت عفونی پاسخ‌های ایمنی بدن پرنده را به چالش وا می‌دارند. بنابراین واکسنی که برای پیشگیری از این بیماری در ماکیان جوان مورد استفاده قرار می‌گیرد هنگامی موثر خواهد بود که دارای سروتیپ در گردش باشد. در این راستا واکسن زنده...

[ 16 ] - Effectiveness of Thermostable Vaccine for Newcastle Disease Produced by the Razi Institute on Backyard Poultry in Iran during 2015

Newcastle disease causes many economic losses to the poultry industry in most countries. This disease is endemic in Iran. Backyard poultry is considered the reservoir of Newcastle virus; however, there is either no vaccination program against Newcastle, or it is performed in a restricted manner. Commercial live vaccines are inactive and sensitive to temperature; moreover, vaccine delivery to vi...

[ 17 ] - Immunogenicity and Efficacy of Live Infectious Bronchitis 793/B.08IR Vaccine in SPF Chickens

Infectious bronchitis virus (IBV) has a variety of serotypes with relatively limited cross-protection leading the disease to be a major problem in the poultry industry. The IBV 793/B strain has identified to circulate in Iran; therefore, the development of a specific vaccine to protect against the virulent virus has received attention. In this regard, the live IB 793/B vaccine (793/B.08IR) was ...
