The antimicrobial susceptibility patterns among veterinary clinical enterococci isolated in Portugal from dogs (n=37) and cats (n=18) with urinary tract infection (n=40), otitis externa (n=11) and pyoderma (n=4) between 1998 and 2006. Enterococcus faecalis was the predominant species isolated (93.6%; n=46) followed by E. faecium (10.9%; n=6). Other species isolated (E. durans, E. gallinarum and E. hirae) accounted for 5.5% (n=3). Susceptibility to penicillin and ampicillin was high (95.5%). Susceptibility to nitrofurantoin (83.6%) and chloramphenicol (69.1%) was high. Resistance to tetracycline and erythromycin (67.3% and 50.9%, respectively) was high. 87.3% of the strains were resistant to dalfopristin/quinupristin. None of the isolates were resistant to vancomycin, teicoplanin or linezolid. Resistance rates for ciprofloxacin and levofloxacin were 45.5% and 41.8%, respectively. 12.7% of the isolates were resistant to gentamicin and 36.4% were resistant to streptomycin.
