The paper presents the results of the study of pathomorphological changes in organs in ornithobacteriosis in decorative pigeons with the establishment of the underlying disease, including the pathological signs associated and pathognomonic for the disease. The objects of the study were the corpses of fallen pigeons of the English postal and peacock breeds, at the age of 2-3 years, kept in a private farm on the territory of the Yemelyanovskiy district of the Krasnoyarsk Territory. Bacteriological examination of the material revealed the causative agent of ornithobacteriosis (Ornithobacterium rhinotracheale), and the causative agent of colibacillosis (Escherichia coli) was also found in 70,0 % of cases. In 70 % of the individuals, a complication was observed in the form of colibacillosis, characterized by serous-catarrhal gastroenterocolitis, spleen hyperplasia, and serous polyarthritis, to the underlying disease. The features of ornithobacterial infection in pigeons include the absence of pronounced serous-inflammatory edema of soft tissues in the head area, signs of serous-fibrinous aerosacculitis and the onset of the disease in birds of the older age group (2-5 years).
