Prevention and control of ruminant mastitis caused by Streptococcus spp. and Staphylococcus spp. and study their diagnostic significant properties

Bacteria Streptococcus spp. and Staphylococcus spp. are most widespread pathogens in aetiology of ruminant´s mastitis for their most important virulence factors. The breed of cattle and sheep in Slovakia in recent years, milk mastitis affected cows and sheep often isolated the bacterial species that were not previously frequented. Targeted reduction of S. agalactiae, S. uberis are accompanied by more frequent occurrence of S. dysgalactiae, S. bovis, S. sanguinis and related species Aerococcus viridans. Recently dominant S. aureus alternated several species of coagulase negative staphylococci.The project is aimed to determine the frequency of Streptococcus spp. and Staphylococcus spp. as well as other kinds of pathogenic bacteria currently involved in aetiology of mastitis. After the evaluation of growth and biochemical properties of bacteria, res. after their taxonomic determination will be tested for sensitivity to antibiotics uses in the treatment of mastitis.
