Role of Administration Routes of Anti - Infectious Bursal Disease Virus (Gumboro) Vaccine on Immunization of Chicken

Infectious bursal disease (Gumboro disease).

Infectious bursal disease (IBD) (Gumboro disease) has been described throughout the world, and the socio-economic significance of the disease is considerable world-wide. Various forms of the disease have been described, but typing remains unclear, since antigenic and pathotypic criteria are used indiscriminately, and the true incidence of different types is difficult to determine. Moreover, the...

Isolation, Characterization and Standardization of New Infectious Bursal Disease Virus for Development of a Live Vaccine

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...

Expression, purification and glycosylation analysis of chicken infectious bursal disease virus VP2 in yeast

Infectious bursal disease (IBD), a highly contagious and devastating disease in young chicken, is causedby infectious bursal disease virus (IBDV). To improve the immunogenicity of recombinant IBDV subunitvaccine, an attempt was made to find a new way to prepare IBD vaccine containing glycosylated mVP2antigen. Firstly, IBDV mVP2 gene (with a nucleic acid sequence encoding B cell epitope of IBDV(...

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...
