Abstract

The prevalence of pharyngeal carriage of group B streptococci was evaluated in patients with and without the complaint of a sore throat by three methods (blood agar plates, Columbia CNA agar plates, and a selective enrichment broth containing gentamicin and nalidixic acid). The overall carriage rate of group B streptococci was 12%, and there was no significant difference between the two groups of patients. The selective broth medium was more sensitive than the two solid agar plate methods in detecting carriage, and 37% of all group B streptococci were recovered solely from the broth. Use of the broth alone would have permitted a 94% detection of the group B streptococcal carriers.

摘要

通过三种方法(血琼脂平板、哥伦比亚CNA琼脂平板以及含有庆大霉素和萘啶酸的选择性增菌肉汤)对有和没有咽痛主诉的患者进行B族链球菌咽部携带情况评估。B族链球菌的总体携带率为12%,两组患者之间无显著差异。在检测携带情况方面,选择性肉汤培养基比两种固体琼脂平板方法更敏感,所有B族链球菌中有37%仅从肉汤中分离出来。仅使用肉汤就能检测出94%的B族链球菌携带者。
