Infectious bursal disease (IBD) is a highly contagious disease of chickens caused by the infectious bursal disease virus (IBDV). This study was conducted to characterize three IBDV strains from Iran. A reverse transcriptase-polymerase chain reaction (RT-PCR) procedure was used to amplify a 715-bp fragment of the VP1 gene from IBDV strains. Amplified VP1 fragments of the three Iranian IBDV strai...

The study was conducted to determine the prevalence of infectious bursal disease virus (IBDV) at different ages in commercial boilers. From Oct 2003 to Nov 2004, bursa samples collected from both vaccinated as well non-vaccinated commercially reared broiler chickens suspected of having infectious bursal disease were analyzed for the presence of IBDV using reverse transcriptase polymerase chain ...

The article presents the results of serological control effectiveness vaccination broilers against infectious bursal disease (IBD) with use vector vaccine INNOVAX-NH-IBH in incubator. Vector vaccines are new generation that do not contain post-vaccination complications birds and interference. These genetically engineered work at cellular level, spectrum protection recombinant is higher than hom...

Introduction Infectious bursal disease (IBD) is an acute contagious viral disease of young chickens known as Gumboro disease (Lasher and Shane, 1994). The etiological agent, IBD virus (IBDV), has a predilection for the cells of the bursa of Fabricius where the virus infects lymphocytes of the B-cell lineage (Burkhardt et al., 1987). Thus, IBD is a fatal immunosuppressive disease causing heavy l...

background: infectious bursal disease virus (ibdv) causes a highly immunosuppressive disease in chickens and is a pathogen of major economic importance to the poultry industry worldwide. the vp2 protein is the major host-protective immunogen of ibdv and has been considered as a potential subunit vaccine against the disease. vp2 coding sequence was cloned in an inducible fungal vector and the pr...
