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: 

1. alpha hemolysis = incomplete lysis of red blood cells, indicated by
   greenish area around colonies
2. gamma hemolysis = no lysis of red blood cells

Note: This plate is a good example of the four quadrant streak plate technique
