Infectious coryza is an acte upper respiratory disease of chickens caused by Haemophilus paragallinarum. Although the disease typically causes only mild clinical signs. the disease is of economic importance. The major effects of the disease are associated with an increased number of unthrifty chicken and a marked reduction (10 to 40 per cent) in egg production, particularly on multiage farms. The disese was first reconised in 1950. The present study is concerned with morphological, cultural and biochemical characterisation of field isolates of avian haemophili and other morphologically or culturally related organisms isolated from cases of infectious coryza from Jabalpur.
