What are alpha hemolytic streptococcus?
Alpha-hemolytic Streptococci Alpha-hemolysis (α-hemolysis) is a partial or “green” hemolysis associated with reduction of red cell hemoglobin. Alpha hemolysis is caused by hydrogen peroxide produced by the bacterium, oxidizing hemoglobin to green methemoglobin.
How do you get strep in your vag?
How do people become carriers of group B Strep?
