Abstract
A modified Streptex kit in which the extraction procedure had been simplified was used to group 200 streptococcal strains. Positive reactions could be obtained with live colonies and over 90% of isolates were correctly grouped from primary isolation plates. Some minor cross-reactions were seen with Streptex, but these were not strong enough to cause any confusion and no isolates were incorrectly grouped. The extraction enzyme in the Streptex kit was relatively poor at extracting the group-specific teichoic acid of group D strains but worked well with groups A, B, C, F and G.
摘要
使用一种提取程序已简化的改良型链球菌分类试剂盒对200株链球菌菌株进行分组。活菌落可产生阳性反应，超过90%的分离株可从初次分离平板中正确分组。使用链球菌分类试剂盒时出现了一些轻微的交叉反应，但这些反应不够强烈，不会造成任何混淆，也没有分离株被错误分组。链球菌分类试剂盒中的提取酶在提取D群菌株的群特异性磷壁酸方面相对较差，但对A、B、C、F和G群菌株效果良好。
