[The bacterial flora and drug sensitivity of chronic tonsillitis in different age groups].

To investigate the pathogenic bacteria and drug sensitivity tests in patients with chronic tonsillitis.We chose a group of patients who were diagnosed chronic tonsillitis as the research object. According to age, they were divided into the children group, the adolescents group and the adults group. Collect secretions of tonsil in the operation, then summarize and analyze the secretions. The detection rate of gram-negative bacteria in adult group was significantly higher than that of children and adolescents groups. Broad-spectrum antibiotics should be preferred in adult patients. While others should choose the antibiotic that is sensitive to gram positive bacterium first, before the pathogenic bacteria and drug sensitivity tests. The multi-drug resistant bacterium infection can not be neglected.
