COLUMBIA BLOOD AGAR BASE
Code：CM0331
Description
Traditionally, blood agar bases have been either casein hydrolysate or meat infusion media. The advantage of the first lies in the rapid production of large colonies, and of the second in clearly defined zones of haemolysis and good colonial differentiation.
Columbia Agar Base （CM0331） （ Ellner et al.1 ） combines the virtues of both these types of media to give an improved all-round performance.
This new base has shown versatility and superior performance in several applications.
Technique
Inoculate the culture suspected to be Clostridium perfringens in a straight line across a plate of Columbia sheep blood agar. Streak an overnight （or older） culture of Streptococcus agalactiae known to produce the CAMP factor at right angles to the first inoculation taking care that the lines do not touch. Incubate anaerobically at 35-37°C for 18-24 hours.
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared plates of medium at 2-8°C.
