INTRODUCTION
Studies on the carriage rate of beta-hemolytic streptococci among children form an important component of public health practice to prevent disease complications such as rheumatic fever/rheumatic heart disease, nephritis, and other local or systemic infections.
METHODOLOGY
Throat swabs collected from asymptomatic schoolchildren were inoculated into appropriate media for isolation of beta-hemolytic streptococci. They were identified by standard biochemical methods and sero-grouped. Antibiotic sensitivity was evaluated using the Kirby-Bauer disk diffusion method.
RESULTS AND CONCLUSION
Beta-hemolytic streptococci were isolated from 106 (7.7%) out of the 1,384 throat swabs and Group F was the predominant sero-group isolated. The highest resistance observed among all the beta-hemolytic streptococci was to trimethoprim-sulfamethoxazole.
引言
儿童中β-溶血性链球菌携带率的研究是公共卫生实践的重要组成部分，有助于预防诸如风湿热/风湿性心脏病、肾炎以及其他局部或全身感染等疾病并发症。
方法
从无症状学童采集的咽拭子接种到合适的培养基中，以分离β-溶血性链球菌。通过标准生化方法对其进行鉴定并进行血清分组。使用 Kirby-Bauer 纸片扩散法评估抗生素敏感性。
结果与结论
在 1384 份咽拭子中，有 106 份（7.7%）分离出β-溶血性链球菌，其中 F 组是分离出的主要血清组。在所有β-溶血性链球菌中观察到的最高耐药性是对甲氧苄啶-磺胺甲恶唑的耐药性。
