• Indended Use :

Description : CTA is a semi solid basal medium that may be used for the detection of organism motility and for maintenance of stock culture. Carbohydrates are added at a concentration of 1%. Fermentation is indicated by a change of colour from red to yellow and motility by the feathering growth of a stab culture. When used for the presumptive identification of Neisseria species a very heavy inoculum should be used for the best result.
