Confirmatory tests for Corynebacterium diphtheriae is
Selective media for Corynebacterium diphtheriae is Tellurite blood agar. Several modifications of Tellurite blood agar have been utilized, such as McLeod's and Hoyle's medium. Tellurite inhibits the growth of most of the other bacteria acting as a selective agent for diphtheria bacilli. Diphtheria bacilli reduce Tellurite to metallic tellurium which is incorporated in the colonies giving them a grey or black colour.
