What is alppha hemolytic?
Alpha hemolysis (α-hemolysis) means that the bacterial enzymes only partially break down the blood cells. This results in the media showing a yellowish/greenish/brownish discoloration (like a bruise) around the colonies, indicating incomplete hemolysis.How to Interpret Beta Hemolysis on Blood Agar: Test for Strep Throat - Identifying B-hemolytic Streptococcus
Why does addition of a bacitracin disk to a blood plate make a rapid identification technique?
In terms of beta hemolytic streptococcus they usually plate this bacteria on blood agar bc when it grows it forms small colonies (bc gram +) with a clear halo around it bc it is hemolytic...this is not the only bacteria to cause hemolysis in blood agar so one might put a bacitracin disk in the plate and bc this inhibits growth of beta hemolytic strep if you see small colonies with clear halos growing everywhere but near the bacitracin disk then this too is indicative of id-ing this bacteria as beta hemolytic strep...hope this helps...enjoy:)
