Determination of the optimal time of vaccination against infectious bursal disease virus (Gumboro) in Algeria.

Virus mutations and their impact on vaccination against infectious bursal disease (Gumboro disease).

Infectious bursal disease (also known as Gumboro disease) is an immunosuppressive viral disease specific to chickens. In spite of all the information amassed on the antigenic and immunological characteristics of the virus, the disease has not yet been brought fully under control. It is still prevalent in properly vaccinated flocks carrying specific antibodies at levels normally high enough to p...

Vaccination of Chicks with an Experimental Oil-emulsion Vaccine against Infectious Bursal Disease Virus

Expression of the VP2 gene of classical D78 infectious bursal disease virus in the methylotrophic yeast Pichia pastoris as a secretory protein

Infectious bursal disease virus (IBDV) is the causative agent of Gumboro disease, an infectious disease of global economic importance in poultry. The expression of heterologous proteins in P.pastoris is fast, simple and inexpensive. In this study, VP2 encoding gene of classical D78 IBDV was amplified using reverse transcription (RT) polymerase chain reaction (PCR) and cloned into pPICZαA vector...

Comparison between Micro and Tube Virus Neutralization Tests for Detection of Serological Responses to Infectious Bursal Disease Virus Following Vaccination

Effect of experimental infectious bursal disease virus on clinical signs and pathogenesis of avian influenza virus H9N2 in turkey by real time PCR

Infectious bursal disease virus (IBDV) in turkeys may result in immunosuppression, and inability of turkeys to resist nonpathogenic or less pathogenic organisms. A total number of 120 day-old commercial male turkeys were purchased and blood samples were collected from 20 day-old turkeys, remaining 100 were divided into four equal groups and kept in separated rooms. Groups 1 and 2 were infected ...
