Abstract

Newcastle disease (ND), endemic in Bangladesh as Ranikhet disease, was investigated in Sonali chickens through a sero-pathological study in Narsingdi district. Active ND cases (14.6% prevalence) were confirmed via clinical signs, post-mortem lesions, and histopathology. Hemagglutination inhibition (HI) assays measured antibody titers in relation to standard vaccination practices.
