[Anaerobic microbes in perimandibular inflammation].
Studies conducted in 16 patients with perimandibular inflammation included bacteriological examinations and tests of the resistance of the bacterial flora to 6 antibiotics:davercin, erythromycine, penicillin, ampicillin, tetracycline and chloramphenicol. A total of 73 strains (47 anaerobic and 26 aerobic) were isolated, including 47 Gram - and 26 Gram's strain +. Anaerobic Gram - ve bacteria appear to be the principal cause of perimandibular inflammatory lesions, streptococcus viridans being identified more frequently in these cases than in the normal buccal cavity. Bacterial flora of dental origin was more sensitive to davercin than to the other 5 antibiotics tested.
