[Sensitivity of Gardnerella vaginalis to antibiotics. Study of 40 strains isolated at the Purpan University Hospital Center of Toulouse].

40 strains of Gardnerella vaginalis were tested for their in vitro susceptibility to 10 antibiotics, by an agar dilution method. All strains were inhibited by 0,5 microgram or less of penicillin and ampicillin. Erythromycin was the most active of the antibiotics tested; for all strains the minimal inhibitory concentrations were less than or equal to 0.06 microgram/ml. All strains were inhibited by 8 micrograms of streptomycin per ml and 4 micrograms of chloramphenicol per ml. 50% of the strains were inhibited by less of 2 micrograms of tetracyclin and all strains tested exhibited MIC greater than or equal to 64 micrograms when tested against colistin, nalidixic acid and sulfafurazole. At least, 85% of strains were inhibited by 2 to 16 micrograms of metronidazole.
