"Live IBD vaccine exacerbates disease and pathological effects of Asian lineage H9N2 LPAIV in chickens."
Avian Pathol. 2023 Jul 13:1-25. doi: 10.1080/03079457.2023.2236994. Online ahead of print.ABSTRACTAvian influenza H9N2 is one of the most circulating viruses in numerous Egyptian poultry farms. The Asian lineage H9N2 exhibits an immunosuppressive effect, and its pathogenicity is amplified when it co-infects with other pathogens, especially with the immunosuppressive infectious bursal disease virus (IBDV), resulting in increased mortality rates. Both vaccines and field infection can exacerbate the pathogenicity of H9N2, particularly in the bursa of Fabricius (B.F), causing more significant lymphoid depletion. To comprehend ...

Recombinant < em > Fowl aviadenovirus E < /em > (FAdV-E) penton base vaccination fails to confer protection against inclusion body hepatitis (IBH) in chickens
Avian Pathol. 2023 Jul 7:1-6. doi: 10.1080/03079457.2023.2226085. Online ahead of print.ABSTRACTInclusion body hepatitis (IBH) is a metabolic disease affecting chickens, associated with different serotypes of fowl adenovirus (FAdV). Experimentally tested vaccines against IBH include several capsid-based subunit vaccines, but not the penton base protein. In the present study, specific pathogen-free chickens were vaccinated with recombinant penton base expressed from each of two different FAdV serotypes (FAdV-7 and FAdV-8b), followed by challenge with a virulent IBH-causing strain. No protection was observed with either vacc...
