Tryptic Soy Blood Agar (TSBA) is intended for the isolation and cultivation of many fastidious and non-fastidious microorganisms found in clinical specimens. This medium is also suitable for use in the CAMP test for the presumptive identification of group B. Streptococci. TSBA is an enriched non-selective medium, supplemented with sheep blood for the hemolytic reactions. It is supplemented with hemin and vitamin K1 to improve the recovery of fastidious anaerobes. This medium is prepared, stored and dispensed under oxygen-free conditions to prevent the formation of oxidized products prior to use.
