Clinical Study on Hjarre's Disease in Poultry

Abstract

Hijarre’s Disease (Coligranuloma) is a disease of adult chicken and turkey, characterized by nodular granulomas in liver, mesentery and walls of intestine. It is caused by Escherichia Coli, a gram -ve , non-acid fast non-spore forming bacillus. Besides coligranuloma, E-coli has more oftenly been incriminated in number of other clinical conditions which include coli bacillosis, coli septicemia, egg peritonitis, arthritis and air saculitis etc. causing decrease in production high mortality rate and condemnation of carcass at slaughter, thereby resulting in major economic losses to the poultry Industry. Coli granuloma is relatively uncommon coliform disease and may cause mortality as high as 75% in an individual flock (calnek et. al 1991). Perusal of literature reveals very meagre information on the occurrence of disease. This communication probably constitutes first report on Hjarre’s disease in Kashmir.
