Group B Streptococcus is a Gram-positive coccus that usually lives in the human vagina and rectum. It is a conditional pathogen, a bacterium that many people carry but have no symptoms. In most cases, Group B Streptococcus does not cause infection or damage to the normal population. In adults, GBS is usually benign. However, for pregnant women and newborns, Group B Streptococcus may become a potential threat.

Impact of Group B Streptococcus on Pregnant Women

Vaginal itching and abnormal vaginal discharge: When pregnant women are infected with Group B Streptococcus, they may experience symptoms such as vaginal itching and abnormal vaginal discharge. This is because the toxicity released by the pathogenic bacteria can stimulate vaginal epithelial cells and affect the pH balance in the vagina.

Urinary tract infection: Group B Streptococcus may also cause urinary tract infection in pregnant women, manifested as symptoms such as frequent urination and painful urination.

Intrauterine infection and adverse pregnancy outcomes: Ascending infection of Group B Streptococcus may cause intrauterine infection, increasing the risk of adverse pregnancy outcomes such as miscarriage, premature birth, and premature rupture of membranes.

Effects of Group B Streptococcus on Newborns

Group B Streptococcus has a more serious effect on newborns. During delivery, newborns may be exposed to Group B Streptococcus through the birth canal of pregnant women, causing infection. This infection may lead to serious diseases such as neonatal sepsis, pneumonia, meningitis, and may even be life-threatening. In addition, even if the newborn survives, it may leave neurological sequelae such as intellectual disability and hydrocephalus.

How to Prevent Group B Streptococcus Infection?

Pregnant women should be screened for Guillain-Barré syndrome (GBS) during pregnancy in the third trimester (usually 36-37 weeks). By testing the vaginal and rectal secretions of pregnant women, it can be determined whether there is Group B Streptococcus infection.

For pregnant women with positive screening results, doctors usually recommend preventive antibiotic treatment before delivery, with the goal of reducing the number of GBS bacteria to reduce the risk of neonatal infection. At the same time, pregnant women should maintain good personal hygiene habits during pregnancy, such as regular washing of the vulva, avoiding unclean sexual behavior, etc., to reduce the possibility of Group B Streptococcus infection.

After a successful delivery, the doctor will closely monitor the baby for signs of Guillain-Barré syndrome infection. This monitoring usually involves watching your baby for 48 hours for symptoms such as difficulty breathing, fever, or unusual sleepiness. In some cases, your doctor may do a blood test or culture to rule out an infection.

Group B Streptococcus is a bacteria that can have health effects on pregnant women and newborns. Understanding Group B Streptococcus and its potential risks is an important part of planning your birth. While a positive GBS test may seem daunting at first, understanding the implications and making the necessary adjustments to your birth plan can greatly reduce the risk to you and your baby. In the meantime, if you or your baby have any symptoms or concerns related to Group B Streptococcus, please consult a doctor.
