Tellurite reduction test to aid in the recognition of Corynebacterium vaginale

R F Smith et al. J Clin Microbiol. 1977 Mar.

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.
