Sensitivity of 100 enterococcal strains isolated from faeces in premature born unit to 15 antimicrobial agents has been studied. 33 strains of Enterococcus faecalis, 61 strains of Enterococcus faecium, 4 strains of Enterococcus casseliflavus and 2 strains of Enterococcus durans were included in this study. MICs to ampicillin, gentamicin, streptomycin, vancomycin, teicoplanin, chloramphenicol, tetracycline, rifampicin, ciprofloxacin, ofloxacin, levofloxacin, sparfloxacin, quinupristin, dalfopristin and quinupristin/dalfopristin were detected by agar dilution method. 53% of strains were resistant to ampicillin, 44 and 39% – to gentamicin and streptomycin, 50, 71 and 93% were resistant to chloramphenicol, tetracycline and rifampicin, respectively. There were no strains fully resistant to vancomycin and teicoplanin. Generally E. faecium was more resistant than other enterococci to most of tested antibiotics with exception of quinupristin/dalfopristin where E. faecalis was more resistant.
