Morphological and Functional Parameters in Calves with Intestinal Diseases

Resumo

The survey focused on studying the dynamics of the morphological and functional parameters for calves with the intestinal diseases. The data on the quantity and species composition of the intestinal microbiota were compiled; the haematological, biochemical, and immunological parameters were measured. In case of domination of the pathogenic microorganisms in the intestinal microbiocenoses, the serous edema and the leukocyte infiltration into the epithelial layer and the lamina propria of intestinal mucosa could be observed; multiple embolizations caused by bacteria in the blood vessels were revealed. Multiple small necrotic foci infiltrated with leukocytes in the liver were recorded. Extensive haemorrhage of blood vessels, cyanosis, hyperaemia, multiple blot haemorrhages, and dystrophic and necrotic processes were found in all the segments of the intestine. Therefore, the above-listed symptoms represent the risk factors for toxemia and bacteremia.
