摘要

The article analyses the data of bacteriological studies of milk taken from dairy cattle for mastitis identification in 2015-2017. The studies involved standard methods to identify germ cultures and investigate their morphological and biological parameters determining the species of the germs. Microbiological methods of investigation were done in compliance with regulatory document "Guidelines to bacteriological study of milk and cow udder secretion" no. 115-69. As a result of bacteriological studies, positive mastitis tests in milk were obtained, a new composition of pathogens of positive samples was determined, the etiological mastitis structure was analyzed over the last recent years. The dynamics of the etiological mastitis structure indicators over 2015-2017 was studied. The analysis of obtained results established that in the south of Tyumen region over the last three years, the number of positive milk test for mastitis decreased twice; the etiological structure of identified subclinical mastitis of productive animals included three types of bacteria, E. coli, St. aureus, Ps. aeruginosa, which were identified both in associated state and as monocultures. The main exciter of subclinical mastitis over the last three years was Staphylococcus aureus with the percentage in the etiological structure of 49.2%.
