Mixed Infection with Infectious Bursal Disease Virus and Aspergillus fumigatus

Characterization of a Highly Virulent Infectious Bursal Disease Virus

Western blot detection of infectious bursal disease virus infection.

In order to evaluate the use of a Western blot methodology for the diagnosis of infectious bursal disease virus (IBDV) infection, chickens were experimentally infected with IBDV strains and tested for the presence of viral antigens and antibodies by a blocking Western blot test (bWB). The viral proteins obtained from the bursa of Fabricius (BF) were transferred to a nitrocellulose membrane afte...

Conformational analysis of Infectious bursal disease virus

Aim: This study was designed to develop peptide analogs of Infectious Bursal Disease (IBD) virus VP5 protein segment having cell penetrating ability to improve their interaction with cargo molecule (Nucleic acid) without affecting the backbone conformation. Materials and Methods: IBDV VP5 protein segment designated as RATH peptide were synthesized using solid phase peptide synthesis and their s...

Very Virulent Infectious Bursal Disease Virus

The primary feature of vvIBDV is the ability to induce high mortality. Mortality ranges from 5% – 25% in broilers and 30% – 70% in layers. Surviving birds are severely affected with a high condemnation rate. vvIBDV induces clinical signs similar to Gumboro disease, which is induced by classical virulent strains of IBDV, except that the disease is more pronounced and acute in individual birds an...

Structure of infectious bursal disease virus.

Infectious bursal disease virus of chickens was purified, and its structure was examined by the negative-staining technique in the electron microscope. The buoyant density of infectious bursal disease virus in CsCl was found to be 1.34 g/cm(3). The morphological details suggest that the capsid of the virion consists of a single layer of 32 capsomeres arranged in 5:3:2 symmetry. The virion measu...
