Abstract

Mastitis is one of the most common diseases on dairy farms and causes significant economic losses associated with the cost of treating sick cows, reduced milk yield and quality of dairy products, as well as the risk of premature culling of animals. Mastitis pathogens are divided into two groups, among which the most important are contagious pathogens that are transmitted mainly from one cow to another, especially through milking equipment, which in turn can lead to infection of the entire dairy herd, so establishing the prevalence of contagious mastitis pathogens is quite relevant today. The aim of this study was to identify and establish the prevalence of contagious mastitis pathogens in tank milk samples by bacteriological and molecular genetic (PCR-RT) studies. The results of the study of contagious pathogens of mastitis in tank milk samples by PCR-RT revealed that the most common are Streptococcus agalactiae - 36% and Streptococcus uberis - 35%. The study of tank milk samples by the bacteriological method showed that the most common detected contagious pathogens are Streptococcus agalactiae - 55 % and Streptococcus uberis - 28 %
