A new type of macrolide resistance in staphylococci from bovine subclinical mastitis.
Staphylococcal (nine Staphylococcus aureus and 14 coagulase negative) strains, isolated from subclinical bovine mastitis, showed three patterns of macrolide resistance: (i) macrolide-lincosamide constitutive resistance; (ii) macrolide generalised resistance; and (iii) lincosamide generalised resistance. The second pattern of resistance appeared to be a new resistance phenomenon. None of the strains showed dissociated or inducible resistance, neither was there any strain which could inactivate erythromycin, oleandomycin, lincomycin or clindamycin.
