  • Title: Aerobic and anaerobic bacteriology of adenoids in children: a comparison between patients with chronic adenotonsillitis and adenoid hypertrophy.
    Author: Brook I.
    Journal: Laryngoscope; 1981 Mar; 91(3):377-82. PubMed ID: 7464399.
    Abstract:
    Adenoids were obtained from 18 children with chronic adenotonsillitis (Group A) and from 12 others with adenoid hypertrophy (Group B). Patients' ages ranged from 20 months to 15 years (mean 6 years); 18 were males and 12 females. The adenoids were sectioned in half after heat searing of the surface, and the core material was cultured for aerobic and anaerobic microorganisms. Mixed aerobic and anaerobic flora were obtained from all patients, yielding an average of 7.8 isolates (4.6 anaerobes and 3.2 aerobes) per specimen. There were 97 anaerobes isolated. The predominant isolates in both groups were: Bacteroides sp. (including B. melaninogenicus and B. oralis), Fusobacterium sp., gram-positive anaerobic cocci, and Veillonella sp. There were 138 aerobic isolates. The predominant isolates in both groups were: alpha and gamma hemolytic streptococci, beta hemolytic streptococci (Group A, B, C, and F), S. aureus, S. pneumoniae, and Hemophilus sp. Hemophilus influenzae type B, and S. aureus were more frequently isolated in Group A. B. fragilis was only recovered in Group A. Beta lactamase production was noted in 27 isolates obtained from 18 patients. Fifteen of these patients belonged to Group A (83% of Group A), while 3 were members of Group B (25% of Group B). These bacteria were all isolates of S. aureus (11) and B. fragilis (2), 8 of 22 B. melaninogenicus group, 4 of 11 B. oralis, and two of 8 H. influenza type B. Our findings indicate the polymicrobial nature of deep adenoid flora and demonstrate the presence of many beta lactamase-producing organisms in children with recurrent adenotonsillitis.
