What is group B strep?
Group B strep (GBS) is a 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, and it usually does not cause any symptoms. However, in certain cases, it can be a dangerous cause of various infections that can affect nonpregnant adults, pregnant women, and their newborn infants. Group B strep infection is the most common cause of sepsis and meningitis in the United States during a newborn's first week of life.
Group B strep infection can also afflict adults with certain chronic medical conditions, such as diabetes, cardiovascular disease, and cancer. Although the incidence of neonatal group B strep infection has been decreasing, the incidence of group B strep infection in nonpregnant adults appears to be increasing.
