ENTEROCOCCI IN A MONTPELLIER HOSPITAL DUR ING SEPTEMBER 1993 - ISOLATED SPECIES, DISTRIBUTION ACCORDING TO SAMPLES, PATHOGENIC ROLE, SENSITIVITY TO BETA-LACTAMS, AMINOGLYCOSIDES, GLYCOPEPTIDES

All enteroccoci isolated during September 1993 were collected in a Mon tpellier hospital. 225 strains remained after elimination of identical one. The species were identified by means of rapid ID 32 Strep. Enter ococcus faecalis (83.5 % of isolates) predominates in genito-urinary t ract and E. faecium (9 % of isolates) in digestive isolates. Based on bacteriological and cytological criteria, we considered 20 % of entero cocci (all samples) as pathogenic as well as 95 % of digestive isolate s and 8.4 % of urinary strains. Disks diffusion test was used for sens itivity to amoxicillin, piperacillin, gentamicin, kanamycin, vancomyci n and teicoplanin. Minimal inhibitory concentrations of two glycopepti des was determined by E-Test. All E. faecalis were sensitive to beta-l actams. 55 % of E. faecium and 3 out of 3 strains of E. gallinarum had reduced sensitivity. High level resistance to aminoglycosides concern ed 42.2 % of strains for kanamycin and 11.5 % of strains for gentamici n. High level resistance glycopeptides was not found.
