[Anaerobic bacteria and their role in recurrent tonsillitis]

The presence of anaerobic bacteria in 100 palatal tonsils obtained during the tonsillectomy, was evaluated in quality and in quantity. 17 species of anaerobic bacteria were found. The most frequent were: Bacteroides melaninogenicus, Peptostreptococcus anaerobius, Peptostreptococcus intermedius, Propionibacterium, Veillonella parvula and Peptococcus asaccharolyticus. In most evaluations their density was 10(5)-10(6) in gram of tonsil tissue, sometimes 10(7). Its role in recurrent tonsils infections was discussed.
