Abstract
One hundred patients subjected to tonsillectomy because of recurrent acute tonsillitis or tonsillar hypertrophy were evaluated bacteriologically both with ordinary throat culturing and cultures from tonsillar cores. In 26% of the patients H. influenzae was isolated and in 20% fl-haemolytic group A streptococci. Growth of B. catarrhalis was obtained in 10% and group C-, group G streptococci or pneumococci in less than 5% each. None of the group A streptococcal strains proved tolerant to penicillin. A much higher isolation rate of H. influenzae was found in cultures obtained from tonsillar core tissue (23%) than from ordinary throat cultures (2%). This was also the fact, though to a lower extent, regarding group A streptococci. H. influenzae and group A streptococci were isolated as often in patients with tonsillar hypertrophy as in patients suffering from recurrent acute tonsillitis, suggesting a role of these bacteria in both conditions.
