During the period from July 2002 to June 2003, infectious bursal disease (IBD) was suspected in 101 commercial flocks of broiler chickens on the basis of clinical and post mortem findings in some districts of the Haryana state, India. Bursal samples were collected randomly from 20 flocks for the detection of infectious bursal disease virus (IBDV) by reverse transcriptionpolymerase chain reactio...

background and aims: infectious bursal disease (ibd) is an acute contagious viral disease of birds worldwide. the causative virus induces a persistent immune suppression following destroy b lymphocytes precursors in bursal lymphoid follicles. vaccination is the main strategy for prevention of the disease in commercial poultry industry. materials and methods: to produce a live vaccine against th...

Infectious bursal disease (IBD) is a highly contagious disease of chickens caused by Infectious bursal disease virus (IBDV). In turkeys, however, infection with classical virulent IBDV strains lead only to subclinical forms of the disease. We attempted to isolate IBDV from the bursa of turkey and characterize it. Amplification of a 743-bp fragment of VP2 gene by RT-PCR and restriction analysis ...

Three propolis samples from East Nile Delta, Egypt were collected. Propolis samples were investigated by GC/MS,103 compounds were identified, 20 being new for propolis. Dakahlia propolis was a typical poplar propolis but it contained two new caffeate esters and two new triterpenoids. Ismailia propolis was characterized by the presence of new triterpenic acid methyl esters and it did not contain...

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...

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...
