Transcriptional profiles in bursal B-lymphoid DT40 cells infected with very virulent infectious bursal disease virus

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...

Characterization of a Highly Virulent Infectious Bursal Disease Virus

Sequence analysis of the VP1 gene in three very virulent Iranian infectious bursal disease virus strains

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...

Evaluation of Experimental Inactivated Infectious Bursal Disease Vaccine Using a Local Very Virulent Pathotype Strain
