www.cdc.govA. Blood agar plate (BAP): trypticase soy agar (TSA) + 5% sheep blood . A BAP is used as a general blood agar medium. It is used for growth and testing of N. meningitidis and S. pneumoniae. The plate should appear a bright red color. If the plates appear dark red, they are either old or the blood was likely added when the agar was too hot. If ...
SELECTIVE AND DIFFERENTIAL MEDIA

Alpha hemolysins partially lyse the red blood cells and reduce the hemoglobin to methemoglobin which produces a green zone around the colony. Beta hemolysins cause complete lysis of the red blood cells

Microbial Growth Culture Media Both Selective and Differential Media : Used both to distinguish colonies of a desired organism, and inhibitthe growth of other microbes.
THE IDENTIFICATION OF TWO UNKNOWN BACTERIA

Colonies produced on this plate will also be used for biochemical testing to determine its identification.

If any of the results are unusual or not expected or the culture is contaminated the test must be repeated.
