Abstract

Analysis of milk micrbiomes from healthy cows and cows with different (clinical and subclinical) forms of mastitis was performed at two farms of the Central Russia. An increase in the operational taxonomic units (OTUs) of bacteria of the phylum Proteоbacteria belonging primarily to Pseudomonadales, Burkholderiales, as well as Streptococcaceae, Staphylococcaceae, and Bacillaceae in the animals with mastitis was detected. The Planococcaceae OTU percentage decreased. The ratio of rarely presented OTUs also changed in the milk of animals with mastitis.
