Abstract
The article presents information on the normative morpho-microbiological indicators of the uterus of black-white Holstein cows, as well as in the subclinical form of endometritis. A complex of methods was used, including clinical examination of animals, anatomical preparation, microscopic morphometry, cytomorphological examination and statistical analysis of the obtained digital data. The studies were carried out on the basis of the Department of Anatomy and Histology of Animals named after Professor A.F. Klimov FGBOU VO MGAVMiB - MBA named after K.I. Scriabin, as well as in ZAO Povadino breeding plant. Cytomorphological studies were carried out on the basis of the Chance Bio laboratory. Objects of research - 20 black-white Holsteinized cows. 2 groups of animals were formed. Group 1 (n=13) - animals with endometritis, of which the acute form of the course (n=3), the latent form (n=10). 2nd group (n=7) - with no signs of this pathology, which is a morphological control. The formation of a group of animals with a normal course of the postpartum period was carried out on the basis of generally accepted methods, including examination of the external genital organs and rectal examinations. The data on the normative morphometric parameters of the uterus, which are basic in the differential diagnosis of its pathologies, are presented. Revealed micromorphological pathognomonic signs of subclinical endometritis. They are expressed in edema and infiltration of the endometrium, its sclerotic transformation, a decrease in the lumen of the uterine glands and their cystic degeneration. In the compared groups, the cytomorphological composition of the vaginal contents was established. In the control group, it was dominated (up to 60%) by surface epithelial cells. In case of subclinical endometritis, Staphilococcus aureus was revealed, Nonhemolytic Lac - fermenting Escherichia
coli and alpha hemolytic Streptococcus viridans group, which indicate the presence of an inflammatory process in the endometrium. The established morpho-microbiological correlations of the state of the uterus are basic in assessing the prognosis of the risk of development and the nature of the course of subclinical endometritis.
