Product Summary and Explanation
In 1955, Leavitt et al. discovered Tryptic Soy Agar (TSA) facilitated vigorous growth of aerobic and
anaerobic microorganisms. TSA, a general purpose medium, is commonly referred to as Soybean-Casein
Digest Agar USP 23. TSA is a nutritious base, and a variety of supplements can be added to enhance this
medium. The addition of 5% sterile, defibrinated sheep, horse, or rabbit blood provides an excellent nonselective
medium, used to determine hemolytic reactions of bacteria. TSA supplemented with lecithin and
Tween 80® is widely used in environmental monitoring.
TSA is recommended in multiple water & wastewater applications, and numerous standard methods for food
testing. This medium also conforms to Harmonized United States Pharmacopoeia (USP), European
Pharmacopoeia (EU), and Japanese Pharmacopoeia (JP). Clinically, TSA is used in the differentiation of
Haemophilus species (the X and V factors are omitted from this medium), and widely used for blood cultures.
TSA is commonly used as a maintenance medium for culture collections, and testing bacterial contaminants
