Summary. Data on the species composition of the uterine microflora in healthy animals and with clinical signs of endometritis in cows are highlighted in the article. All studies were carried out on the basis of the North Caucasian Zonal Research Veterinary Institute in the laboratory of infectious pathology of farm animals. The main purpose of our research was to conduct a comparative characterization of the microflora of the uterus in healthy and sick cows with endometritis. The object of the study was red-and-white cows (20 heads) from a farm located in Bolshie Saly vlg., Myasnikovsky district, Rostov region. All animals included in the experiment were divided into two groups of 10 animals in each: 1st - clinically healthy animals, 2nd -animals with signs of inflammation of the uterus. According to the classification, all identified microorganisms were divided by the authors into the following groups: 1) pathogenic microorganisms - directly related to inflammatory processes in the endometrium; 2) conditionally pathogenic microorganisms - this type of microorganisms is harmful and leads to inflammation in the endometrium only when they multiply excessively in the uterine cavity; 3) microorganisms belonging to the normal uterine flora. After the study, the authors analyzed the species composition of the microflora in both groups of animals under study. The main microorganisms that cause clinical signs in endometritis, according to the authors’ data, are Escherichia coli hemolytic, Staphylococcus aureus, Streptococcus uberis, Staphylococcus haemolyticus, Trueperella pyogenes и Proteus vulgaris, which are pathogenic and opportunistic microflora of the uterus in cows.

Keywords: endometritis, microflora, uterus, bacteriological studies, conditionally pathogenic microorganisms, pathogenic microorganisms, microorganisms of normal uterine flora, inflammation, cows, nutrient media, sensitivity to antibacterial drugs.
