[Bacteroides fragilis. Its isolation and antibiotic sensitivity].

The authors chose the problem of the isolation of bacteroides fragilis in pathological samples to present a method of identification of strict anaerobic gram negative bacteria, suitable for use in a routine bacteriological laboratory. A selection of 20 strains led them to study the mean inhibitory concentration of these germs with regard to antibiotics. From this study, two groups were obtained: one of low activity, the other of greater activity in vitro, in which one may note certain tetracyclines, clindamycin and metronidazole.
