Comparison of the surface and core bacteria in tonsillar and adenoid tissue with Beta-lactamase production.

Abstract

Adenoidectomy and tonsillectomy, indicated for children with recurrent or persistent symptoms of infection or hypertrophy, are among the most frequent operations performed in children. This study was carried out for investigating the microbial flora of the tonsils and adenoids regarding to core and surface microorganisms and also pathogen microrganisms' beta-lactamase production rate. Cultures were taken from the core and surface of tonsils and adenoids of the 91 patients at the time of the surgery for tonsillectomy and adenoidectomy. Aerobic and anaerobic cultures were inoculated and identified. Beta-lactamase production was detected also. The most frequently isolated aerobic microorganisms were Streptococcus viridans and Neisseria spp. The number of the microorganisms isolated from the tonsil core compared to the surface of the tonsils was found statistically insignificant (P > 0.05). The number of the adenoid surface aerobic microorganisms was found higher from the adenoid core (P < 0.05). The amount of adenoid and tonsil core anaerobic microorganisms were alike. The patients' preoperative antibiotherapy whether using beta-lactam or beta-lactamase resistant were compared for beta-lactamase producing bacteria production and the number of beta-lactamase producing bacteria were found statistically insignificant (P > 0.05). The togetherness of Staphylococcus aureus and other beta-lactamase producing bacteria was found statistically significant (P < 0.05). This study demonstrates that there is polymicrobial aerobic-anaerobic flora in both adenoids and tonsils. There was a close relationship between the bacteriology of the tonsil and adenoid flora. Staphylococcus aureus and and other beta-lactamase producing bacteria may be responsible for treatment failures in patients with tonsillitis.
