儿童扁桃体及腺样体肥大细菌学分析

目的探讨扁桃体、腺样体肥大病儿扁桃体、腺样体表面和实体组织内的菌群种类、分布情况及药物敏感程度。方法随机选取扁桃体、腺样体肥大并拟行手术的病儿60例,分别于术前用咽拭子取扁桃体、腺样体表面分泌物,术后取两者实体组织行细菌培养及药物敏感性试验。结果4组标本培养结果均以正常菌群为主。条件致病菌以肺炎链球菌、金黄色葡萄球菌、肺炎克雷伯杆菌为主,且在各组的分布无显著性差异（P〉0.05）。药物敏感试验显示,3种条件致病菌对头孢菌素类抗生素和β-内酰胺酶抑制剂复合药物较敏感,而对单纯青霉素耐药。结论使用咽拭子取扁桃体表面分泌物行细菌培养及药物敏感试验,结果基本可以反映扁桃体实体组织及腺样体表面和实体组织的菌群种类、药物敏感程度。

BACTERIOLOGICAL ANALYSIS OF HYPERTROPHY OF TONSIL AND ADENOID IN CHILDREN

Objective To explore the bacteria flora, their distribution and drug sensitivity on the surface and in the tissue of hypertrophic tonsil and adenoid in children. Methods Sixty children with hypertrophy of tonsil or adenoid scheduled for operation were chosen at random. The surface secretion of the glands collected by a throat swab before operation and entity tissue removed by surgery were sent for bacterial culture and drug sensitivity test. Results The results of germiculture in four groups were mainly normal microbial population. The conditional pathogenic bacteria were mainly S. pneumoniae, S. aureus and subsp. Pneumonine, and the difference of distribution was not significant among the groups （P〉0.05）. The drug susceptibility showed that the three opportunists were sensitive to cephalosporin and compound preparation of β-lactamase suppressant, and insensitive to pure penicillin. Conclusion The results of bacterial culture and drug sensitivity from gland surface specimen taken by throat swab can reflect the microbial population of the glands and their drug sensitivity.
