慢性扁桃体炎的细菌学研究

Microbiology of recurrent tonsillitis and chronic tonsillitis with rheumatisms

对复发性慢性扁桃体炎（ＲＣＴ）、迁延性慢性扁桃体炎（ＰＣＴ）及可疑病灶性扁桃体炎（ＦＣＴ），３组共４０例患者的扁桃体进行了细菌培养和组织学观察。细菌培养：平均每个扁桃体检出菌种数为６．８株：需氧菌３．６株，厌氧菌３，２株。金葡菌在需氧致病菌中占首位，厌氧菌第一位为类杆菌（其中以产黑素类杆菌为首位）。组织学观察发现：ＰＣＴ组扁桃体微小脓肿较其它２组常见；表明，慢性扁桃体炎是由需氧菌和厌氧菌共同参与的多微生物的混合感染。并对产黑素类杆菌的致病机理进行了讨论。

Abstract A qualitative analysis of microflora from the tonsillar surface and core of patients of chronic tonsillitis with or without rheumatisms was undertaken. Histopathological changes of the tonsils were examined with microscope. Results showed that staphylococcus aureus isolates were in a higher recovery rate in tonsils with persistant chronic tonsillitis group.The predominant anaerobic organisms were bacteroides,of which bacteroides melaninogenicus were the most prevalent anaerobic bacteria in these groups. The microabscess was more often found in tonsils in persistant chronic tonsillitis group.These findings suggest a possible pathogenic role for the bacteroides melaninogenicus in chronic tonsil infection.
