INDENTIFICATION OF ANAEROBIC BACTERIA IN PYOGENIC ORAL INFECTION

In order to determine the prevalence of anaerobic bacteria associated with pyogenic oral infection, the author studied the specimens from twenty patients who visited the Department of Oral Surgery, K.N.U. Hospital during the period from Feb. 1985 to Nov. 1985. In this study, author used GLC (gas liquid chromatography) combined with conventional biochemical method and API-20A system. The result were summarized as follows; The average number of anaerobic bacteria in each specimen was 2.8. Total 56 strains of obligate anaerobes were identified These strains were as follows: Anaerobic gram positive cocci 17 strains (30.4%) Anaerobic gram negative cocci 1 strains (1.8%) Anaerobic gram positive bacilli 11 strains (19.6%) Anaerobic gram negative bacilli 27 strains (48.2%) The most frequent strain was Bacteroides spp. (35.7%) Gas liquid chromatographic (GLC) profiles of cellular fatty acids and metabolic products were useful in identifying Peptococcus spp., Peptostreptococcus spp., Eubacterium spp.
