What is Group B Strep?

Group B Streptococcus (GBS) is a type of bacteria that is commonly found in the intestines and lower genital tract of both men and women. It is estimated that between 10-30% of adults are colonized with GBS at any given time. GBS is usually harmless and does not cause any symptoms or health problems in healthy adults.

However, GBS can cause serious infections in certain groups of people, including newborn babies, pregnant women, the elderly, and people with weakened immune systems. In newborns, GBS can cause life-threatening infections such as pneumonia, meningitis, and sepsis. In pregnant women, GBS can lead to urinary tract infections, chorioamnionitis (infection of the placenta and amniotic fluid), and postpartum infections.

GBS can be transmitted from mother to baby during childbirth, which is why it is important for pregnant women to be screened for GBS between 35-37 weeks of pregnancy. If a pregnant woman tests positive for GBS, she can receive antibiotics during labor to reduce the risk of infection in the newborn. Antibiotics such as penicillin or ampicillin are typically used to treat GBS infections.

However, in recent years, there has been an increasing concern over antibiotic resistance in GBS. Some strains of GBS have become resistant to certain antibiotics, making them more difficult to treat. This has led researchers to explore alternative treatment options, such as the use of doxycycline, which has shown promising results in vitro and in animal studies.
