What is strep A vs Strep B?

Group B Streptococcus (GBS) is a type of gram-positive streptococcal bacteria also known as Streptococcus agalactiae. This type of bacteria (not to be confused with group A strep, which causes strep throat) is commonly found in the human body (this is termed colonization), and it usually does not cause any symptoms.
