GC AGAR BASE (VEG.)

G.C. Veg Agar Base with added blood or haemoglobin and other supplements is recommended for selective isolation and cultivation of fastidious organisms like Gonococci and Haemophilus species. This medium can also be employed as a basal medium in the preparation of Chocolate Veg Agar and Thayer Martin Veg Medium Base. Originally, animal based Chocolate Agar was developed by Johnston for the growth of fastidious Neisseria gonorrhoeae within 24 hours. Addition of haemoglobin to this medium had improved the growth, as studied by Carpenter and Morton. Incubation is to be done at 37?C in an atmosphere of 5-10% carbon dioxide and 70% humidity. It is recommended that all presumptive Neisseriae should also be confirmed by carbohydrate fermentation tests and other serological tests.
