Blood agar plate. Blood agar plates (BAPs) contain mammalian blood (usually sheep or horse) typically at a concentration of 5–10%. BAPs 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. .

Disk diffusion test - Wikipedia

The disk diffusion test or agar diffusion test or Kirby–Bauer test is an antibiotic susceptibility test. It uses antibiotic discs to test the extent to which bacteria are affected by those antibiotics. In this test wafers containing antibiotics are placed on an agar plate where bacteria have been placed and the plate is left to incubate. If an antibiotic stops the bacteria from growing or kills the bacteria there will be an area around the wafer wher...
