Group B Strep In Pregnancy: Test, Risks & Treatment
Overview
What is group B strep?
Group B strep infection (also GBS or group B Streptococcus) is caused by bacteria typically found in a person's vagina or rectal area. About 25% of pregnant people have GBS, but don't know it because it doesn't cause symptoms. A pregnant person with GBS can pass the bacteria to their baby during vaginal delivery. Infants, older adults or people with a weakened or underdeveloped immune system are more likely to develop complications from group B strep.
Most newborns who get GBS don't become sick. However, the bacteria can cause severe and even life-threatening infections in a small percentage of newborns. Healthcare providers screen for group B strep as part of your routine prenatal care. If you test positive, your provider will treat you with antibiotics.
How do you get group B strep?
GBS bacteria naturally occur in areas of your body like your intestines and genital and urinary tracts. Adults can't get it from person-to-person contact or from sharing food or drinks with an infected person. Experts aren't entirely sure why the bacteria spreads, but they know that it’s potentially harmful in babies and people with weakened immune systems.
When do you get tested for group B strep?
The Centers for Disease Control and Prevention (CDC) recommends routine screening for group B strep in all pregnancies. You're screened for GBS between 36 and 37 weeks of pregnancy. Group B strep testing involves your provider taking a swab of your vagina and rectum and then sending it to a lab for analysis.
Can Group B strep affect a developing fetus?
GBS doesn't affect the fetus baby while it's still inside your uterus. However, your baby can get GBS from you during labor and delivery. Taking antibiotics for GBS reduces your chances of passing it to your baby.
How does a baby get GBS?
There are two main types of Group B strep in babies:
- Early-onset infection: Most (75%) babies with GBS become infected in the first week of life.
GBS infection is usually apparent within a few hours after birth. Premature babies face greater risk if they become infected, but most babies who get GBS are full-term. - Late-onset infection: GBS infection can also occur in infants one week to three months after birth. Late-onset infection is less common and is less likely to result in a baby's death than early-onset infection.
How common is GBS?
Group B strep screening during pregnancy has decreased the number of cases. According to the CDC, about 930 babies get early-onset GBS, and 1,050 get late-onset GBS. About 4% of babies who develop GBS will die from it.
Symptoms and Causes
What are the symptoms of group B strep?
Most adults don't experience symptoms of group B strep. It can cause symptoms in older people or people with certain medical conditions, but this is rare. These symptoms include:
- Fever, chills and fatigue.
- Difficulty breathing.
- Chest pains.
- Muscle stiffness.
Newborns with GBS have symptoms like:
- Fever.
- Difficulty feeding.
- Irritability.
- Breathing difficulties.
- Lack of energy.
These symptoms can become serious quickly because newborns lack immunity. Group B strep infection can lead to severe problems like sepsis, pneumonia and meningitis in infants.
Can I pass group B strep to my partner?
Other people that live with you, including other children, aren't at risk of getting sick.
Diagnosis and Tests
Will I be tested for group B strep?
Yes, your healthcare provider will test you for GBS late in your pregnancy, around weeks 36 to 37.
Your obstetrician uses a cotton swab to obtain samples of cells from your vagina and rectum. This test doesn't hurt and takes less than a minute. Then, the sample is sent to a lab where it's analyzed for group B strep. Most people receive their results within 48 hours. A positive culture result means you're a GBS carrier, but it doesn't mean that you or your baby will become sick.
If you’re using a midwife, you might be given instructions on how to test yourself at home and submit the swab to a lab.
Is Group B strep an STD?
No, group B strep isn't an STD (sexually transmitted disease). The type of bacteria that causes GBS naturally lives in your vagina or rectum. It doesn't cause symptoms for most people.
Management and Treatment
What happens if you test positive for group B strep during pregnancy?
Healthcare providers prevent GBS infection in your baby by treating you with intravenous (IV) antibiotics during labor and delivery. The most common antibiotic to treat group B strep is penicillin or ampicillin. Giving you an antibiotic at this time helps prevent the spread of GBS from you to your newborn. It's not effective to treat GBS earlier than at delivery. The antibiotics work best when given at least four hours before delivery. About 90% of infections are prevented with this type of treatment.
One exception to the timing of treatment is when GBS is detected in urine.
When this is the case, oral antibiotic treatment begins when GBS is identified (regardless of the stage of pregnancy). Antibiotics should still be given through an IV during labor.
Any pregnant person who has previously given birth to a baby who developed a GBS infection or who has had a urinary tract infection in this pregnancy caused by GBS will also be treated during labor.
How is group B strep treated in newborns?
Some babies still get GBS infections despite testing and antibiotic treatment during labor. Healthcare providers might take a sample of the baby's blood or spinal fluid to see if the baby has GBS infection. If your baby has GBS, they're treated with antibiotics through an IV.
Prevention
How can I reduce my risk of group B strep?
Anyone can get GBS. Some people are at higher risk due to certain medical conditions or age. The following factors increase your risk for having a baby born with group B strep:
- You tested positive for GBS.
- You develop a fever during labor.
- More than 18 hours pass between your water breaking and your baby being born.
- You have medical conditions like diabetes, heart disease or cancer.
Getting screened for GBS and taking antibiotics (if you're positive) is the best way to protect your baby from infection.
Outlook / Prognosis
What are long term problems of Group B strep in newborns?
Infants with GBS can develop meningitis, pneumonia or sepsis. These illnesses can be life-threatening. Most infants don't develop any long-term issues; however, about 25% of babies with meningitis caused by GBS develop cerebral palsy, hearing problems, learning disabilities or seizures.
Can I get tested for group B strep again?
No, once you test positive for GBS, you're considered positive for the rest of your pregnancy. You will not get re-tested.
Do I need treated for group B strep if I am having a c-section?
No, you don't need antibiotics if you're having a c-section delivery.
However, you'll still be tested for GBS because labor could start before your scheduled c-section. If your water breaks and you're GBS positive, your baby is at risk of contracting the disease.

When should I see my healthcare provider if I’m positive for group B strep?
In some cases, GBS causes infections during pregnancy. Symptoms of infection include fever, pain and increased heart rate. Let your provider know if you have any of those symptoms as it could lead to preterm labor.
GBS can also cause urinary tract infection (UTI), which requires oral antibiotics.
Talk to your provider about what you can expect during labor and delivery if you have group B strep.
A note from Cleveland Clinic
Try not to panic if your healthcare provider tells you you're positive for group B strep during pregnancy. It's caused by bacteria that occur naturally in your body, not by anything you did wrong. The chances of you passing group B strep to your baby are quite low, especially if you take antibiotics during labor.
Talk to your provider about group B strep and share any concerns you have. In most cases, testing positive for GBS causes no problems, and your baby is healthy.

Synonyms: Streptococcus group B (S. agalactiae) Culture.
Brief description of the study "Culture for group B beta-hemolytic streptococcus (Streptococcus group B, S.
agalactiae)" Group B streptococcus (GBS, Streptococcus agalactiae) causes severe illness in newborns and is dangerous for certain patients other age groups.
In the vast majority of cases, newborns become infected with GBS during maternal deliveries, with a higher incidence during vaginal delivery. GBS causes early neonatal infections such as sepsis, meningitis, pneumonia, osteomyelitis, arthritis, and pyelonephritis, with rates ranging from 0.2 to 5 or more per 1,000 live births in different countries. In obstetric practice, group B streptococcus is associated with bacteremia, urinary tract infections, chorioamnionitis, premature rupture of amniotic fluid, preterm labor, postpartum endometritis, etc.
GBS in the human body can colonize the oropharynx, anal area of the rectum, vagina (usually vestibule), urogenital tract, skin.
It has been established that GBS in 5-35% of women can be detected in the vagina and often in the urethra of their sexual partners A significant association of carriage of GBS in the vagina has been shown not only with early septicemia of newborns, but also with spontaneous miscarriages, premature birth, premature rupture of amniotic fluid , urinary infection in pregnant women, the birth of children with low body weight, the development of chorioamnionitis in childbirth, endometritis and sepsis in puerperas.
The highest level of colonization in women of reproductive age and pregnant women. In pregnant women, GBS is isolated from the listed areas in 7-30% of cases (more often in young people who have high sexual activity or use intrauterine contraceptives). Of these, 60-75% remain GBS carriers until the end of pregnancy.
Vaginal-rectal swabs are collected to detect colonization of the vagina of pregnant women with group B streptococcus. In all other cases, the biomaterial is taken only if there are clinical signs of infection.
GBS has a natural sensitivity to beta-lactam antibiotics, including penicillins. Determination of sensitivity is necessary in cases where the patient has an individual intolerance to drugs of this group.
Isolateable microorganisms and pathogens:
- Streptococcus agalactiae.
What is the purpose of culture for group B beta-hemolytic streptococcus (Streptococcus group B, S. agalactiae)? in order to identify bacteriocarrier and determine the need for antibiotic prophylaxis during childbirth, to prevent neonatal complications (septicemia, pneumonia and neonatal meningitis).
What can affect the result of the test "Culture for beta-hemolytic streptococcus group B (Streptococcus group B, S. agalactiae)"
Failure to follow the rules for preparing for the study may affect the result of the test.
Express diagnostics of streptococcus
There are a huge number of pathogenic organisms, and the most common pathogens of infectious diseases are group A streptococci. These are round-shaped microorganisms that cause diseases such as:
- pharyngitis
- tonsillitis
- impetigo
- pyoderma
- paraproctitis
- vaginitis
- sepsis
- pneumonia
- endocarditis
- pericarditis
- osteomyelitis
- purulent arthritis
- myositis
- phlegmon
- omphalitis
- scarlet fever
- erysipelas
- toxic shock syndrome
- necrotizing fasciitis
- rheumatism
- acute glomerulonephritis
Symptoms
The clinical picture of the disease may differ depending on the age of the patient, the affected organ and the presence of concomitant diseases.
In a child, the disease manifests itself more rapidly. Chills first, followed by the following symptoms:
- nausea and vomiting
- green or yellow nasal discharge
- decreased appetite
- enlarged lymph nodes
- sore throat and sore throat
- increase in body temperature to high levels.
In adults, streptococcal infections are often very severe. Patients have the same symptoms of the disease that are characteristic of children, but they are more pronounced.
Pregnant women and people with poor health should be especially attentive to their health and protecting the body from streptococcal infection.
Diagnosis
Group A streptococcal infection can be detected in several ways. To determine the pathogen, the following medical studies are carried out.
- Bacteriological culture. The biomaterial taken from the patient (sputum, mucus, saliva, blood, urine) is examined for the isolation of a separate pathogen.
