Tryptose Blood Agar Base w/ Yeast Extract is a tryptose based medium that can be used for the cultivation of fastidious organisms, on supplementation with blood. This medium is devoid of dextrose and therefore useful in determining the haemolytic reactions. Tryptose Blood Agar Base w/ Yeast Extract provides additional nutrients (yeast extract) to the fastidious organisms. Tryptose Blood Agar Base w/ Yeast Extract can be used as a general-purpose medium without supplementation of blood. This medium can be used to determine the heamolytic reactions of fastidious organisms.
The four different types of haemolysis observed are as follows:
a) Alpha haemolysis: partial lysis of the erythrocytes surrounding a colony, causing a gray green or brownish discolouration in the media.
b) Beta haemolysis: complete lysis of the red blood cells surrounding a colony, causing a clearing of blood from the medium.
