Molecular characteristics of fowl adenovirus strains detected in broiler chickens on diets without immunostimulant supplements.

Introduction: Outbreaks of fowl adenovirus (FAdV) infection in chicken flocks in Poland threaten birds' health and lives and are rising in frequency. The risk of these infections in immunocompromised poultry flocks with developed clinical symptoms was analysed through virus detection in broiler chicks and correlation of cases with the birds' immune strength.
