Group B Strep
Group B Streptococcus (GBS) is a type of bacterial infection that can pose significant health risks, particularly for newborns, pregnant women, and individuals with compromised immune systems. Its presence can lead to severe complications if not adequately managed.
While it is generally harmless in adults, its transmission during childbirth can result in severe infections in newborns, including sepsis, pneumonia, and meningitis.
Causes of Group B Strep Infections
The primary cause of Group B Strep infections is the colonization of the bacteria in the body. While many carry the bacteria asymptomatically, certain conditions can precipitate an infection. These include:
- Pregnancy: Pregnant women can pass the bacteria to their babies during labour.
- Weakened Immune Systems: Individuals with compromised immunity are more susceptible to infections.
- Chronic Medical Conditions: Conditions such as diabetes and liver disease can increase risk.

Get A Second OpinionSymptoms of Group B Strep
In adults, Group B Strep may not present noticeable symptoms, but for infants, the symptoms can be severe and often require immediate medical attention. Common symptoms in newborns include:
- Fever
- Difficulty feeding
- Irritability or lethargy
- Breathing difficulties
In adults, potential symptoms might include urinary tract infections, skin infections, and in severe cases, bloodstream infections.
Diagnosis of Group B Strep
Diagnosis of Group B Strep typically involves microbiological cultures. Pregnant women are routinely screened between weeks 35 and 37 of gestation through a vaginal and rectal swab to detect the presence of GBS.
Group B Strep Diagnosis in Adults
In adults, the diagnosis often depends on the symptoms presented. Urine cultures, blood tests, and swabs from infected areas can help detect the bacteria.
Treatment for Group B Strep
Treatment for Group B Strep in adults often involves antibiotics, such as penicillin or ampicillin. In pregnant women, the focus is on preventing transmission to the newborn. Prophylactic antibiotics are administered during labour if the mother tests positive for GBS.
Antibiotic Prophylaxis in Pregnancy
Antibiotic prophylaxis is a standard preventive measure for pregnant women who test positive for GBS or have risk factors such as:
- Previous birth of a baby with GBS infection
- Fever during labour
- Preterm labour

Book an AppointmentManagement and Prevention of Group B Strep
The management of Group B Strep focuses on preventing the onset of infections, particularly in newborns and vulnerable adults.
Preventive Measures in Pregnancy
- Routine Screening: Pregnant women should undergo GBS screening during the third trimester.
- Intrapartum Antibiotics: Administering antibiotics during labour to women who test positive.
- Educating Expectant Mothers: Informing about the risks and preventive strategies for GBS.
General Prevention Strategies
- Hygiene Practices: Regular handwashing and personal hygiene can reduce the spread of bacteria.
- Healthy Lifestyle Choices: Maintaining a balanced diet and regular exercise can strengthen the immune system.
Group B Strep and Pregnancy: Special Considerations
Pregnancy introduces specific considerations concerning Group B Strep. The potential transmission of GBS from mother to child during childbirth necessitates vigilant screening and management strategies to prevent neonatal infections.
Risk Factors for GBS in Pregnancy
- GBS Colonization: Being a carrier of GBS significantly increases the risk of transmission to the baby.
- Premature Rupture of Membranes: Increases the risk of GBS infection in the newborn.
- Multiple Births: Twins or more can increase the risk of transmission.
Exercises and Lifestyle for Expectant Mothers
Regular physical activity and prenatal exercises can boost immunity and overall health, potentially reducing the risk of infections. However, pregnant women should consult healthcare providers before starting any exercise regimen.
