Intended Use:

Recommended for cultivation of fastidious organisms and studying haemolytic reactions. It provides improved and enhanced haemolysis.

Product Description:

Microserv-Blood agar plates (Microserv-BA) contain sheep blood at a concentration of 5–10%. Microserv-BA are enriched, differential media used to isolate fastidious organisms and detect hemolytic activity. β-Hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony. Examples include Streptococcus haemolyticus. α-Hemolysis will only cause partial lysis of the red blood cells (the cell membrane is left intact) and will appear green or brown, due to the conversion of hemoglobin to methemoglobin. An example of this would be Streptococcus viridans. γ-Hemolysis (or nonhemolytic) is the term referring to a lack of hemolytic activity. Microserv-BA also contain meat extract, tryptone, sodium chloride, and agar as nutrient to support the growth of bacteria.
