Macrolide and lincosamide (ML) resistance and the related resistance genes of staphylococci were assessed from cases ofbovine subclinical mastitis. Of the 104 Staphylococcus aureus and 62 coagulase negative staphylococcus (CoNS) isolates, 26 (25%) and12 (19.4%) were resistant to ML, respectively. While constitutive ML resistance phenotype accounted for 15.4% (16/104) of S. aureusand 8.1% (5/62) of CoNS, inducible ML resistance phenotype accounted for 2.9% (3/104) of S. aureus and 3.2% (2/62) of CoNS.Among erythromycin-resistant isolates, single or various combination of different resistance genes were detected. The results of thisstudy showed that ML resistance was prevalent among staphylococci from subclinical bovine mastitis cases in Hatay, Turkey. Therefore,a continuous surveillance is necessary to minimise the spread of antimicrobial-resistant staphylococci.
