Definition
Potassium Tellurite Agar is a medium used for the differentiation of Enterococcus species.
The selectivity of this medium is due to the presence of potassium tellurite, which inhibits the growth of most bacteria associated with Enterococcus species. The differentiation of Enterococcus species is based on their capacity to reduce potassium tellurite into tellurium, which gives the colonies a black colour.
