ABSTRACT
The genus enterococcus has 12 species of which, E faecalis and E faecium are most important in human infections. A progressive resistance to penicillin and ampicillin has been detected in these species. The aim of this work was to identify Enterococcus species isolated in a hospital and to study their antimicrobial susceptibility. We studied 209 Enterococcus species coming from patients admitted to a public hospital. Their susceptibility to penicillin, ampicillin, imipenem, vancomycin, tetracycline, chloramphenicol, ciprofloxacin, gentamycin and streptomycin was determined with the agar dilution technique. Eighty seven percent of species were E faecalis and 7,1 percent were E fecium, other isolated species were E hirae, E casseliflaws, E avium, E solitarius and E faecalis variant. 38 percent of these species were isolated from the urinary tract, 22 percent from the skin and 14 percent from surgical wounds. All E faecalis species were susceptible to penicillin, ampicillin, imipenem and vancomycin; 27,3 percent were susceptible to tetracycline, 54,7 percent to chloramphenicol and 80 percent to ciprofloxacin. Seventy three percent of E faecium species were susceptible to penicillin, 80 percent to ampicillin and 60 percent to imipenem. 62 percent of E faecalis and 42.4 percent of E faecium were resistant to streptomycin. It is concluded that the correct identification of Enterococcus species has therapeutic implications
