No hemolysis on blood agar corresponds to which type?

Hemolysis patterns on blood agar are the clue. When red blood cells are not lysed around the bacterial colonies, this is called gamma hemolysis. The surrounding agar stays unchanged in color because there’s no hemolysis. In contrast, alpha hemolysis shows a greenish halo from partial hemolysis, and beta hemolysis shows a clear zone from complete lysis. So “no hemolysis” points to the gamma type, which is the standard label for this pattern.
