| 目的：分析儿童手术切除的扁桃体腺样体分离菌的分布及药敏特征，为其临床预防和治疗提供指导。方法：将483 例扁桃体
腺样体进行细菌培养，分析潜在致病菌组成及其药敏特征。结果：扁桃体和腺样体的细菌培养阳性率分别为66.43%和52.88%，主
要病原菌及其分离率分别为金黄色葡萄球菌(20.71%)、流感嗜血杆菌(15.11%)、肺炎链球菌(10.97%)、A 群链球菌(6.42%)，金黄色
葡萄球菌对青霉素的耐药率达82%，21%菌株为MRSA，流感嗜血杆菌茁- 内酰酶检测阳性率为30.92%，复方新诺明和氨苄西林
耐药率较高，分别为50.69%和30.14%，肺炎链球菌对青霉素耐药率为32.08%，红霉素、四环素、复方新诺明耐药率高，分别为
81.13%、79.25%和69.81%，A 群链球菌对青霉素仍然100%敏感，红霉素、克林霉素、四环素的耐药率高，分别为83.87%、77.42%、
58.06%。结论：扁桃体和腺样体主要分离菌有金黄色葡萄球菌、流感嗜血杆菌、肺炎链球菌、A 群链球菌，不同检出菌的耐药性差
异明显，临床可根据常见检出分离菌的分布及药敏特征预防和治疗感染。 |

| 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. |
