[Pattern of antimicrobial susceptibility of enterococci strains].
Enterococci resistance to antimicrobials has increased lately. We studied the susceptibility to 12 antimicrobials of 150 enterococci strains coming from hospitalized and outpatients, using the agar dilution method. Teicoplanin, followed by imipenem and amoxicilin-clavulanic acid had the lower minimal inhibitory concentrations. No strains of E faecalis was resistant to ampicillin, whereas 14% of E faecium had minimal inhibitory concentrations over 8 micrograms/ml. The high minimal inhibitory concentrations of cefpirome (64 micrograms/ml) renders this antimicrobial useless in the treatment of enterococcal infections. Betalactamase production and resistance to glucopeptides were not detected. Antimicrobial susceptibility of strains coming for hospitalized or outpatients were similar.
