Fowl Adenovirus Infection – Potential Cause of a Suppressed Humoral Immune Response of Broilers to Newcastle Disease Vaccination

Abstract

Fowl adenovirus infections have a significant economic impact, especially in the production of broilers. It is considered the leading cause of three syndromes: adenoviral gizzard erosions and ulcerations, inclusion body hepatitis, and hepatitis-hydropericardium syndrome. A critical feature of this virus is its immunosuppressive effect, via suppressing humoral and cellular immunity.
