Vaccination with a fowl adenovirus chimeric fiber protein (crecFib-4/11) simultaneously protects chickens against hepatitis-hydropericardium syndrome (HHS) and inclusion body hepatitis (IBH)

open access: yesVaccine, 2022
In the past decades, fowl adenovirus (FAdV)-related diseases became an increasing concern for the poultry industry worldwide. Various immunization strategies against FAdVs have been experimentally investigated, with a particular focus on subunit vaccines against hepatitis-hydropericardium syndrome (HHS), caused by FAdV serotype 4, and inclusion body ...

Protection of chickens against hepatitis-hydropericardium syndrome and Newcastle disease with a recombinant Newcastle disease virus vaccine expressing the fowl adenovirus serotype 4 fiber-2 protein

Vaccine, 2020
Newcastle disease (ND) is one of the most important and devastating avian diseases with considerable threat to the global poultry industry. Hepatitis-hydropericardium syndrome (HHS), caused by virulent fowl adenovirus serotype 4 (FAdV-4), is another highly infectious disease in chickens with severe economic impact.

Pathogenicity of Avian Adenoviruses Type D and Type E Isolated from Field Cases of Inclusion Body Hepatitis–Hydropericardium syndrome (IBH–HPS) in Broiler chickens in Egypt

International Journal of Veterinary Science, 2023
In this study, 210 one-day-old commercial broiler chicks were used to investigate the pathogenicity of two types of Avian Adenoviruses (type D and type E) recently isolated from field cases. These chicks were divided into four groups; birds of group 1 (G1) and group 2 (G2) were experimentally inoculated with two local isolates of fowl aviadenovirus ...
