Abstract :

Studies were undertaken to evaluate the clinical, gross, histopathological and some biochemical
parameters in broiler birds suffered from E. necatrix infection in a local broiler farm in the Aizawl district.
Clinically, 20 birds out of 100 no. (aged between 4-6 weeks) showed loss of appetite, unthriftiness and
bloody diarrhoea with mucus. Postmortem examination revealed anaemic pale musculature, distended
small intestine with petechial haemorrhages. Similar changes were also observed in some areas of the
large intestine and caecum. Histopathological examination showed severe haemorrhagic enteritis with
necrosis and disintegration of glandular epithelial cells. Several schizonts were observed in the epithelial
cells along with merozoites, infiltrating neutrophils and eosinophils. Biochemically, the infected broilers
presented hypoglycaemia associated with a reduction in liver glycogen level. Biochemical serum analysis
of coccidia infected chickens also showed a significant increase (p<0.01) in alanine amino transferase
levels (2.9-245.2) and there were also changes in total protein and cholesterol level in the serum.
