Nucleotide sequences of the VP2 hypervariable region (VP2-HVR) of 14 infectious bursal disease viruses (IBDVs) isolated in Tanzania from 2001 to 2004 were determined. Phylogenetic analysis showed that the isolates diverged into two genotypes and belonged to the very virulent (VV) type.

A novel vaccine against infectious bursal disease virus (IBDV) has been developed. The new vaccine was constructed by mixing bursal disease antibody (BDA) contained in whole antiserum with live IBDV before lyophilization. To establish various formulations of BDA and IBDV, several BDA doses between 5 units and 80 units of BDA/50 microliters were mixed ...

Infectious Bursal Disease Virus (IBDV)
2019Infectious bursal disease virus (IBDV) is one of the most important viral pathogens of chickens. This virus causes great economic losses to the poultry industry due to factors like high mortality rates and poor growth performance of the affected chickens.

The aim of the present study is to use Physalis mottle virus (PhMV) coat protein (CP) as a scaffold to display the neutralizing epitopes of Infectious bursal disease virus (IBDV) VP2. For this, three different chimeric constructs were synthesized by replacing the N-terminus of PhMV CP with tandem repeats of neutralizing epitopes of IBDV VP2 and ...

Susceptibility of chicken blood lymphoblasts and monocytes to infectious bursal disease virus (IBDV)
Archives of Virology, 1987PHA-M stimulated lymphoblasts obtained from peripheral blood and separated from small lymphocytes by X 1 g velocity sedimentation, unstimulated blood lymphocytes, monocytes and cells isolated from the bursa of Fabricius of chickens, were infected in vitro by the pathogenic strain CU-1 of infectious bursal disease virus (IBDV). Six hours after infection

Summary After oral infection with the highly virulent strain Cu-1 of IBDV, viral antigen can be detected at first four hr p. i. in macrophages and lymphoid cells of the caecum, one hr later also in such cells of the duodenum and jejunum. These cells are therefore to be considered as the place of first virus replication (organ of primary affinity ...

The use of viral vectors for transgenic expression of immunogenic proteins is a current trend in the poultry industry. The objective of this work was to assess the protection against the variant E of infectious bursal disease virus (IBDV), conferred by day-one vaccination with a commercial recombinant herpesvirus of turkey (HVT) vaccine (VAXXITEK ...

The capsid of infectious bursal disease virus (IBDV), with a size of 60-65 nm, is formed by an initial processing of polyprotein (pVP2-VP4-VP3) by VP4, subsequent assemblage of pVP2 and VP3, and the maturation of VP2. In Sf9 cells, the processing of polyprotein expressed was restrained in the stage of VP2 maturation, leading to a limited production of ...

Large plaque (LP) and small plaque (SP) variants of Infectious Bursal Disease Virus (IBDV) which are formed in vitro after serial passages in CE-cells at low or high multiplicities of infection were tested for their pathogenic properties in susceptible chickens.

The evolution of very virulent (vv) infectious bursal disease virus (IBDV) has led to significant economic losses in many poultry-producing areas. Despite vigorous vaccination strategies, IBDV has been difficult to control. The protective efficacy of IBDV vaccines is traditionally evaluated in specific pathogen-free (SPF) chickens.
