What Is Group B Streptococcus (GBS)?

Group B Streptococcus, also known as Group B Strep or GBS, is a bacterium found in the intestines or lower genital tract of roughly 20%-40% of all healthy adult women. While the GBS bacterium is generally harmless in the mother, it can cause severe illness, injury, or death in newborns who have not yet developed the antibodies necessary to fight the infection. Group B Strep can transmit from the mother to the fetus and cause fetal brain damage, cerebral palsy (CP), meningitis, sepsis, pneumonia, hearing loss, and/or blindness.

What Causes Group B Strep Infection?

Group B Streptococcus bacterium occurs naturally in women’s intestines and genital tracts. In a healthy woman’s body, GBS may be present for short periods of time, recur, or exist permanently. The infection can transmit to a fetus through direct contact with the uterus, but newborns more commonly contract it during delivery from contact with bacteria in the birth canal.

What Are the Signs and Symptoms of GBS Infection?

Most carriers of Group B Streptococcus show no physical signs or symptoms, so oftentimes they don’t know they have it. For this reason, the presence of GBS is very dangerous, and physicians are obligated to run diagnostic tests, usually in the third trimester. Signs and symptoms associated with untreated GBS include:

  • Urinary tract infection (UTI): The GBS bacterium can lead to urinary tract infections in mothers, so the presence of a UTI can signify the bacterium.
  • Premature rupture of the membranes (PROM), which occurs when the chorion and amniotic sac rupture before 37 gestational weeks or 18 hours before labor.
  • Fever during labor
  • Gastrointestinal and kidney issues
  • Maternal sepsis, pneumonia, and meningitis
  • Breathing, heart, and blood pressure irregularities

What Are the Risk Factors for Group B Streptococcus Infection?

Michigan lawyers handling cases related to Group B Streptococcus (GBS) and cerebral palsy (CP)When the risk factors for GBS infection are present, it is crucial that the doctor closely monitor the mother and baby. Risk factors for Group B Strep include:

  • Previous delivery of baby with the GBS infection, which signifies the presence of the bacteria in a mother’s body, thus increasing her chance of another Group B Strep delivery.
  • Premature rupture of the membranes (PROM): The amniotic fluid is what protects a fetus from Group B Streptococcus bacteria and prevents the spreading of infection. When a mother’s water breaks, the baby loses this buffer and comes in contact with the infection.

How Is Group B Strep Diagnosed and Treated?

Medical professionals are obligated to conduct a GBS screening during a mother’s third trimester (with the best results occurring five weeks before delivery, so roughly between the 35th and 37th week of pregnancy).

If the patient tests positive as a carrier of Group B Streptococcus, doctors must prescribe antibiotic treatments during labor to protect the baby. If the woman has already delivered the baby and doctors suspect the presence of GBS infection, they must send a sample of the baby’s blood or spinal fluid to the lab for testing. For maximum protection against infection, physicians should administer antibiotics to the newborn even before receiving test results confirming presence of GBS.
