Medium: Blood Agar Plate (BAP)
- a type of enrichment medium
- Sample: "fresh" throat swab (represents properly collected/stored sample)
- Macroscopy:
- Ample growth (3+ score) - higher amount of growth as compared to the old, "dry" swab sample
- Notice the presence of several colony morphologies/types of hemolysis:
- alpha hemolysis = incomplete lysis of red blood cells, indicated by
greenish area around colonies - gamma hemolysis = no lysis of red blood cells
Note: This plate is a good example of the four quadrant streak plate technique
