Methicillin resistance and slime positivity of staphylococci isolated from bovine mastitis [Siǧir mastitislerinden i̇zole edilen stafilokoklarda metisilin direnci ve slaym pozitifliǧi]

The aims of this study were to determine the slime formation and methicilline resistance in isolated staphylococcus species from bovine mastitis. material of this study was consisted of 339 milk samples with mastitis taken from 152 dairy cattle rearing. identifications of isolated microorganisms on genus basis were performed with standart biochemical methods while sequence analysis was used for species basis identification of coagulase negative (cns) and coagulase positive (cps) staphylococcus strains. methicilline resistance of stapylococcus strains were performed with disk diffusion method by using cefoxitin disk and slime formation was detected with congo red agar method. cns were the most common cause (24.s%) of mastitis in cows while cps (5. aureus) were the most second (20.9%). 16 (10.4%) staphylococcus strains were found as methicilline resistance while 55 (35.7%) were slime positive from 154 stapylococcus strains. it was determined that slime formation has no effect on methicilline resistance in cns and cps staphylococcus strains. it was thought that methicilline resistance is beginning a problem,methicilline resistance and slime production may be important factors in the treatment of staphylococcal mastitis in the near future in aydin.
