| Abstract: | Lusitano horses were investigated in order to detect the presence of vancomycin‐resistant enterococci. vanA isolates showed high level vancomycin (Minimum inhibitory concentration; MIC ≥128 mg/l) and teicoplanin resistance (MIC 64 mg/l), as well as resistance to ciprofloxacin, erythromycin and tetracycline. The tet(L) and erm(B) genes, associated with tetracycline and erythromycin resistance, respectively, were found in all vanA isolates. The intestinal tract of Lusitano horses can be a potential reservoir for vanA‐containing enterococci. |
