ABSTRACT

In this paper, the authors report the results of studies aimed at identifying pathological processes in the
lungs, liver and kidneys in calves with catarrhal bronchopneumonia. Statistical analysis of the data had
shown that the severity of lymphoid infiltration was 8.15% in the lung tissue, 7.47% in the liver and
25.45% in the kidneys. The exudate accumulations in the lung tissue were 36.45%, the percentage of
hemorrhages was 13.19 in the lungs and 10.43 in the kidneys. The edema corresponded to 17.13% in the
liver tissue, and 14.72% in the kidneys. Hyperemia in the vessels of the liver was 11.77%. The severity of
granular dystrophy was 42.42% in the liver, and 18.17% in the kidneys. The results obtained should be
used in the complex diagnosis of the disease, as they complement knowledge of pathomorphological changes
in the lungs, liver and kidneys in cattle with catarrhal bronchopneumonia, which makes it possible to
improve the pathoanatomical and differential diagnosis of this disease.

Key words : Lungs, liver, kidneys, calves, bronchopneumonia
