What is group B strep?
Group B strep (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, 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. In the United States, approximately 19,800 cases of GBS infection occur annually across all age groups. Group B strep infection is the most common cause of
neonatal sepsis and meningitis in the United States.
Group B strep infection can also afflict nonpregnant adults with certain chronic medical conditions, such as diabetes, cardiovascular disease, obesity, and cancer. The incidence of GBS infection in adults increases with age, with the highest rate in adults 65 years of age and older (20-25 cases per 100,000). Although the incidence of neonatal group B strep infection has been decreasing, the incidence of
GBS infection in nonpregnant adults has been increasing.
