Media for isolation, detection and cultivation of a wide variety of microorganisms. Synonym: Tryptone Soy Agar, Trypticase Soy Agar, CASO agar, Soybean-Casein Digest Agar, TSA
The nutritional composition of Tryptic Soy Agar has made it a popular medium for many years. It is the medium specified as Soybean-Casein Digest Agar Medium in the United States Pharmacopeia and in the European Pharmacopeia for the total aerobic microbial count portion of the microbial limit testing procedures.
The prepared medium is used for a multitude of purposes including maintenance of stock cultures, plate counting, isolation of micro-organisms from a variety of materials. It is included in the compendia of methods for the examination of water, waste-water and foods.
The use of this medium in clinical microbiology is limited since it does support the growth of a variety of fastidious bacteria. However, since Tryptic Soy Agar does not contain the X and V growth factors, it may be used in determining the requirements for these growth factors by isolates of Haemophilus species by the addition of X, V and XV factor strips to inoculated plates.Tryptic Soy Agar may also be used as a medium for maintaining or subculturing reference strains, e.g., Enterobacteriaceae and staphylococci. The unsupplemented medium is not used as a primary isolation medium for clinical applications. After the addition of blood (e.g., 5% sheep blood), it can be used for the isolation of bacteria from clinical specimens.
Composition: (In 41g TSA/1L H2O)
Tryptone : 15.0g/lit.
Soya Peptone : 5.0g/lit.
NaCl : 5.0g/lit.
K2HPO4 : 2.5g/lit.
Agar : 13.5g/lit.
