Compatibilità

selective and differential for Corynebacterium spp.

Applicazioni

Tinsdale Agar is used for the primary isolation and identification of Corynebacterium diptheriae.
The medium differentiates between C. diphtheriae and the diphtheroids found in the upper respiratory tract. This differentiation was based on the ability of C. diphtheriae to produce grayish-black colonies, surrounded by a brown/black halo. Diphtheroids do not have this ability. The dark halo is due to the production of H2S from cystine and sodium thiosulfate, interacting with the tellurite salt.

Nota sulla preparazione

Suspend 40.7g of agar base in 1000ml of distilled water. Bring to the boil and dissolve completely. DO NOT AUTOCLAVE. Allow to cool to 50°C and add aseptically the contents of 1 unit (part A+B) of Tinsdale Supplement (Cat. No. 73831). Mix throughly and pour into sterile dishes.

Nota a piè di pagina
