A recombinant Newcastle disease virus (NDV) expressing VP2 protein of infectious bursal disease virus (IBDV) protects against NDV and IBDV.
Infectious bursal disease virus (IBDV) causes a highly immunosuppressive disease in chickens. Currently available, live IBDV vaccines can lead to generation of variant viruses. We have developed an alternative vaccine that will not create variant IBDV. By using the reverse genetics approach, we devised a recombinant Newcastle disease virus (NDV) vector from a commonly used vaccine strain LaSota...
متن کاملProtective Vaccination against Infectious Bursal Disease Virus with Whole Recombinant Kluyveromyces lactis Yeast Expressing the Viral VP2 Subunit
Here we report on vaccination approaches against infectious bursal disease (IBD) of poultry that were performed with complete yeast of the species Kluyveromyces lactis (K. lactis). Employing a genetic system that enables the rapid production of stably transfected recombinant K. lactis, we generated yeast strains that expressed defined quantities of the virus capsid forming protein VP2 of infect...
متن کاملVaccination against very virulent infectious bursal disease virus using recombinant T4 bacteriophage displaying viral protein VP2.
In order to develop a desirable inexpensive, effective and safe vaccine against the very virulent infectious bursal disease virus (vvIBDV), we tried to take advantage of the emerging T4 bacteriophage surface protein display system. The major immunogen protein VP2 from the vvIBDV strain HK46 was fused to the nonessential T4 phage surface capsid protein, a small outer capsid (SOC) protein, result...
متن کاملCloning and secretory expression of VP2 gene of infectious bursal disease virus in eukaryotic cells
VP2 gene coding region of a vaccinal strain (D78) of infectious bursal disease virus (IBDV) was clonedin a eukaryotic expression vector, pSec Tag2A. The gene was placed downstream of Ig κ chain leadersequence, under the control of human cytomegalovirus (hCMV) immediate early enhancer and promoter. Theconstruct pSec Tag2A-VP2 was transfected in COS-7 cell line and the expression and secretion of...
متن کاملCloning and Expression of VP2 Gene of Infectious Bursal Disease Virus in Eukaryotic Cells
Infectious bursal disease (IBD) is an economically important viral disease of chickens with worldwide distribution which suppresses the immune system of young chickens. VP2 is the major host-protective protein of infectious bursal disease virus (IBDV). The encoding region of VP2 protein was PCR amplified from a plasmid containing a cDNA fragment of large genomic segment of IBDV, strain D78. Thi...
