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 106.9±0.2. The mean concentration of anaerobic bacteria was 106.2±0.1 and of facultatively anaerobic bacteria 105.7±0.2.", }
