Quantitative bacteriology of acute dento-alveolar abscesses. 1986

M A Lewis, and T W MacFarlane, and D A McGowan

A qualitative and quantitative bacteriological study was performed on pus specimens obtained by needle aspiration of 50 acute dento-alveolar abscesses. Most samples contained a mixture of species (average 3.3); 20 (40%) of the abscesses contained anaerobes alone, 3 (6%) contained facultative anaerobes only and the remaining 27 (54%) contained mixtures of both types of bacteria, with anaerobes predominating. In total, 166 bacterial strains were isolated, 75% of which were strictly anaerobic; the most common species were Peptococcus spp, Bacteroides oralis and B. melaninogenicus. Among facultative anaerobes, Streptococcus milleri was particularly common. The mean concentration of bacteria in each abscess was 10(6.9 +/- 0.2). The mean concentration of anaerobic bacteria was 10(6.2 +/- 0.1) and of facultatively anaerobic bacteria 10(5.7 +/- 0.2).

UI	MeSH Term	Description	Entries
D010460	Peptococcus	A genus of gram-positive, anaerobic, coccoid bacteria that is part of the normal flora of the mouth, upper respiratory tract, and large intestine in humans. Its organisms cause infections of soft tissues and bacteremias.
D010482	Periapical Abscess	Acute or chronic inflammation of tissues surrounding the apical portion of a tooth, associated with the collection of pus, resulting from infection following pulp infection through a carious lesion or as a result of an injury causing pulp necrosis.

D001439	Bacteroides	A genus of gram-negative, anaerobic, rod-shaped bacteria. Its organisms are normal inhabitants of the oral, respiratory, intestinal, and urogenital cavities of humans, animals, and insects. Some species may be pathogenic.

D001443	Prevotella melaninogenica	A species of gram-negative, anaerobic, rod-shaped bacteria originally classified within the BACTEROIDES genus. This bacterium has been isolated from the mouth, urine, feces, and infections of the mouth, soft tissue, respiratory tract, urogenital tract, and intestinal tract. It is pathogenic, but usually in association with other kinds of organisms.	Bacteroides melaninogenicus

D013291	Streptococcus	A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
