Bacterial flora from the tonsil core and tonsil surface of patients with habitual tonsillitis

Abstract

This is a detailed study of the aerobic and aneeobic bacteria from on the crypta tonsillaris and the parenchymatous tonisillaris of 12 patients sufering from habitual tonsillitis. Ninety-two strains from 19 species of aerobic bacteria and 60 strains from 22 species of anaerobic bacteria were isolated and identified from the tonsil surface, were 47 strains of 14 aerobic species and 24 of 10 aerobic species from the tonsil core. The bacteria detected were Streptococcus pyogenes, S. salivarius, S. sanguis, S. mitis, Branhamella catarrhalis, Haemophilis influenzae, Peptostreptococcus sp., Bacterioides sp., etc.In each patient, an average of 12.7 species of bacteria were found on the crypta tonsillaris which consisted of 7.7 species of aerobic bacteria and 5 species of anaerobic bacteria. The amounts of bacteria found were 1.35×106 CFU/ml and 0.93×106 CFU/ml, respectively. In the tonsil core, an average of 6.3 species were detected with 3.9 being aerobic and 2.3 being anaerobic. The amount found were 0.93×106 CFU/ml and 0.83×106 CFU/ml, respectively.Some strains of S. aureus, Branhamella, H. influenzae, Bacterioides melaninogenicus and B. oralis were able to synthesize β-lactamase.
