Abstract: A native chicken carcass was presented with the history of diarrhoea, wing paralysis, emaciation, dull and depression followed by death. At necropsy, the bird revealed enlargement, congestion and diffused greenish yellow necrotic foci on liver. Haemorrhages were noticed in the follicles of proventriculus. Gizzard revealed erosion and congestion. Caecal core consisting necrotic debris and diphtheritic materials covered with thickened wall was noticed. Raised, congested and diffused pale or white necrotic foci were noticed on the kidney and spleen. Parasitological examination of intestinal contents revealed Heterakis gallinarum and Raillietina sps. Caecal mucosal scrapings and liver impressions showed the presence of amoeboid form of Histomonas meleagiridis. High mortality in poultry due to diseases causing severe economic loss to the farmers but early diagnosis and use of proper therapeutic measures with improved managemental cares can save the birds.
