Milk microflora for mastitis in cows

Abstract

Mastitis in cows is currently a pathology that causes great economic damage to livestock farms around the world. The quantitative and qualitative indicators of milk are decreasing. Prevention and treatment of breast inflammation in cows is one of the main tasks of veterinarians. For successful treatment, it is necessary to understand the etiology, especially in infectious mastitis. In order to determine the pathogenic microflora that causes mastitis in cattle, we conducted a bacteriological study of 10 milk samples from cows with breast inflammation in one of the livestock farms of the North-Western region. For the bacteriological study of milk, each sample was taken into a sterile disposable plastic container, the first trickles of milk were pre-deposited. As a result of the conducted studies, mastitis in cows caused by different microorganisms is observed, it follows that not only the farm has its own microbial landscape, but in each case different microorganisms cause mastitis. Cultures of conditionally pathogenic microflora - enterobacteria, coccoid microflora – were isolated from the material. Cultures of Salmonella, Pseudomonas aeruginosa, Staphylococcus aureus and other pathogenic microflora were not isolated in any sample. High resistance of staphylococci to antibacterial drugs of different groups was revealed. Based on the data obtained, it is worth noting the need for a bacteriological study before each appointment of mastitis treatment in cattle, especially during antibacterial therapy. It is necessary to take into account the developing resistance in pathogenic and conditionally pathogenic microorganisms. It is also important to note the relevance of creating a drug for the specific prevention of mastitis of cows of bacterial etiology.
