title: [Enterococci as uropathogens. Frequency of isolation and sensitivity to antibacterial agents].
abstract: 221 clinically significant enterococcal strains (191: E. faecalis, 27: E. faecium, 3 others) were isolated from the urine of patients hospitalised with UTI over an 18-month period (1995-1996). The susceptibility of the isolates to 8 antimicrobial agents was determined by agar dilution method (NCCLS). All enterococci were sensitive to vancomycin and most of them (over 92%) to penicillin and ampicillin. Only 3.14% of E. faecalis and 3.70% of E. faecium were resistant to ciprofloxacin. A relatively high incidence of resistance of enterococci to aminoglycosides was observed: 46.07% and 51.85% to streptomycin, 42.41% and 44.44% to gentamicin, 70.68% and 77.78% to amikacin for E. faecalis and E. faecium, respectively. Among the resistant to penicillin and amino glycosides enterococci of the two species was found a great percent "high level" resistance. There were no beta-lactamase producers among our strains. The established multiresistance accompanied by "high level" resistance requires careful consideration of antimicrobial therapy of enterococcal UTI.
