That is a good question! In beta hemolysis there is colorless zone around the colony of bacteria. There is complete lysis of the red blood cells. This indicates the virulence of the bacteria. In alfa hemolysis, there is green coloration around the bacterial colony. This indicate the partial virulence. Gamma hemolysis means no destruction of the red blood cells. So streptococcus viridens can affect the caries tooth and damaged valve only. By the way caries tooth cause mild rheumatism like the rheumatic heart disease. You can cure the patient of rheumatism by taking out the caries tooth / teeth.

Hemolytic streptococcus is a group of bacteria that can cause various infections in humans, including strep throat, skin infections, and invasive diseases such as pneumonia and sepsis. These bacteria can be classified into different groups based on their hemolytic properties (alpha, beta, or gamma) when grown on blood agar plates. Beta-hemolytic streptococci are known for producing toxins that cause the breakdown of red blood cells.
What is the name of the bacteria that causes strep throats?
Streptococcus
Is Streptococcus pyogenes always Beta hemolytic?
Almost always - stress on 'almost'. There are sporadic cases of nonhemolytic or alpha hemolytic S. pyogenes. So beta hemolysis is usable for quick screens, but is not 100% percent reliable.
Alpha hemolytic reaction in blood agar culture?
Alpha hemolytic reaction in blood agar culture is characterized by partial hemolysis of red blood cells, forming a greenish discoloration around bacterial colonies. This is commonly seen with organisms like Streptococcus pneumoniae, which release hydrogen peroxide that causes the partial breakdown of red blood cells. Alpha hemolysis is distinguished from beta hemolysis (complete lysis of red blood cells) and gamma hemolysis (no hemolysis).
Group A beta hemolytic streptococcus may precede what?
Acute glomerulonephritis
