Objective:To explore the distribution of isolated bacteria and its drug susceptibility feature in culture of tissues from
tonsil adenoidectomy in children, and provide instructions for the clinical prevention and treatment.Methods:483 cases of adenoid tonsil
samples were collected for bacterial culture, the main isolated bacteria and drug susceptibility feature were analyzed.Results:The
positive rate of pathogenic bacteria was 66.43%and 52.88%for tonsil and adenoid samples respectively. There were four main bacteria,
including , , , , which accounted for
20.71%, 15.11%, 10.97%, 6.42% respectively. had a resistant rate of 82% to penicillin, of which 21% isolates were MRSA.
While for , the positive rate of beta-lactamase was 30.92%, with a high resistant rate of 50.69% and 30.14% to
trimethoprim-sulfamethoxazole and ampicillin respectively. had a resistant rate of 32.08%to penicillin, with a
high resistant rate of 81.13%, 79.25%and 69.81%to erythromycin, tetracycline, trimethoprim-sulfamethoxazole respectively. For group
A streptococcus, no resistance to penicillin was detected, with a high resistant rate of 83.87%, 77.42% and 58.06% for erythromycin,
clindamycin, tetracycline.Conclusion:The main isolated potential pathogenic bacteria included , ,
, . There were obvious differences of the drug resistance among them, which could afford good
instructions for its clinical prevention and treatment of pediatric tonsil and adenoid infection. |
