Abstract
Supression of immune response to Newcastle disease vaccines is the main result in this investigation with Eimeria tenella infection especially one day old. Some coccidial stages were also seen in the bursal duct connecting the bursa with the cloaca. Histopathological sections from bursa Fabrici appear free from coccidial stages. On the other hand sections from the cecal wall revealed haemorrhages and necrosis but end with healing and recovery in chicks infected one day old. Relation between Newcastle disease haemagglutinating inhibiting (HI) antibody titres and cecal coccidiosis were also discussed.
