Comparison of the Surface and Core Bacteria in Tonsillar and Adenoid Tissue With Beta-Lactamase Production

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 togetherness of Staphylococcus aureus and other beta-lactamase producing bacteria was found statistically significant ( P
