Abstract

Isolation and identification of pathogenic bacteria, with special reference to Ornithobacterium
rhinotracheale associated with respiratory diseases, were performed from a total of 253 biomaterials collected from 125 layers of 35 commercially reared layer farms in Namakkal of Tamil Nadu state. In total, 27 (51.9%), 18 (34.6%), 5 (9.6%) and 2 (3.8%), isolates were identified as Escherichia coli, Ornithobacterium rhinotracheale, Pasteurella multocida and Haemophilus paragallinarum respectively. Ornithobacterium rhinotracheale, one of the causative agents of the emerging respiratory diseases of poultry could be isolated either singly or concurrently with other bacteria such as Escherichia coli and Haemophilus paragallinarum, indicating its possible etiological role in respiratory disease.
