Abstract

Corynebacterium vaginale (Haemophilus vaginalis) does not reduce potassium tellurite. When a 1% aqueous solution of tellurite is added to starch agar plates previously inoculated with vaginal discharge material, other starch-fermenting and most non-starch-fermenting bacteria rapidly reduce tellurite to produce black or gray colonies. This test is a useful adjunct to methods for rapid presumptive identification of C. vaginale. C. vaginale is more susceptible to tellurite inhibition than a variety of other gram-positive bacteria.

摘要

阴道棒状杆菌(阴道嗜血杆菌)不能还原亚碲酸钾。当将1%的亚碲酸钾水溶液添加到先前接种了阴道分泌物的淀粉琼脂平板上时,其他淀粉发酵菌和大多数非淀粉发酵菌会迅速将亚碲酸钾还原,产生黑色或灰色菌落。该试验是快速初步鉴定阴道棒状杆菌方法的有用辅助手段。与多种其他革兰氏阳性菌相比,阴道棒状杆菌对亚碲酸钾抑制作用更敏感。
