Application Notes |
Tryptic Soy Agar is used for the isolation and cultivation of fastidious and non-fastidious micro-organisms. It supports the abundant growth of fastidious organisms such as Pneumococci, Streptococci, Neisserias, etc. Since it lacks carbohydrates, it is very useful in the study of hemolytic reactions and also in the preparation of chocolate agar. Also, it may be used for sterility testing. It can be used with or without blood supplement. It is used as precultivation medium and enumeration (E. coli) acc. to membrane-filter technique. As it does not contain the X and V factors, it is suitable for identification of Haemophilus sp. by adding X (Hemin) and V (DPN) factors strips. |
