The recurrence of streptococci acute tonsillitis is a complication that often motivates the tonsillectomy. We studied the colonisation of tonsils and adenoids by S. pyogenes and other beta haemolytic streptococci in both surgical indications, recurrent tonsillitis and tonsillar hypertrophy.
We made for aerobic culture the following specimens, throat swabs, tonsils and adenoids tissue corresponding to 47 children referred for tonsillectomy.
S. pyogenes was isolated in 11 cases (23.4%) of tonsils and other beta haemolytic non A streptococci was isolated in 11 cases, of them, group C streptococci was the most frequent with six cases. However in the recurrent tonsillitis group, S. pyogenes was isolated more significantly (47%) that other beta haemolytic streptococci (5.8%). Otherwise in the tonsilar hypertrophy group, S. pyogenes was isolated in the 10% while that other streptococci was isolated in the 33.3%. The culture of 38 adenoids yielded S. pyogenes and beta haemolytic group C streptococci in 6 cases each one (15.7%).
S. pyogenes was isolated more frequently in recurrent tonsillitis that other micro-organisms while that in the tonsilar hypertrophy group predominated streptococci beta haemolytic non A, S. aureus and H. influenzae. Is of interest that the adenoids in our study showed an important reservoir of beta haemolytic streptococci. The throats swabs yielded less of the half of all beta haemolytic streptococci isolated in tonsilar tissue cultured.
链球菌性急性扁桃体炎复发是一种常促使进行扁桃体切除术的并发症。我们研究了化脓性链球菌和其他β溶血性链球菌在扁桃体和腺样体中的定植情况，研究对象包括因复发性扁桃体炎和扁桃体肥大这两种手术指征而接受治疗的患者。
我们对47名因扁桃体切除术前来就诊的儿童的以下标本进行了需氧培养，包括咽拭子、扁桃体和腺样体组织。
在11例（23.4%）扁桃体中分离出化脓性链球菌，在11例中分离出其他β溶血性非A链球菌，其中C组链球菌最为常见，有6例。然而，在复发性扁桃体炎组中，化脓性链球菌的分离率（47%）显著高于其他β溶血性链球菌（5.8%）。在扁桃体肥大组中，化脓性链球菌的分离率为10%，而其他链球菌的分离率为33.3%。38份腺样体培养物中，有6例（15.7%）分离出化脓性链球菌和β溶血性C组链球菌。
化脓性链球菌在复发性扁桃体炎中的分离频率高于其他微生物，而在扁桃体肥大组中，以β溶血性非A链球菌、金黄色葡萄球菌和流感嗜血杆菌为主。有趣的是，我们研究中的腺样体显示出是β溶血性链球菌的一个重要储存库。咽拭子中分离出的β溶血性链球菌不到扁桃体组织培养中分离出的所有β溶血性链球菌的一半。
