🎧FREE MSRA PODCAST –Group B Streptococcus (GBS): What Every Clinician Needs to KnowToday we’re breaking down Group B Strep (GBS), themost important cause of early severe infection in UK newborns — and an absolutemust-know for the MSRA, clinical practice, and safe maternity care. 📝Key Learning Points📌Definition &Significance• Group B Streptococcus (Streptococcus agalactiae)— a common bacterium found in the gut and genital tract of many healthy adults.• Most important asthe leading cause of early-onset sepsis,pneumonia, and meningitis in UK newborns.• Up to 20–40% ofpregnant women may carry GBS — usually without symptoms.📌Transmission &Risk Factors• Babies are exposedduring birth (passage through the birth canal of a carrier mother).• High-yield risk factors: – Maternal GBS carrier status – Intrapartum fever – Previous baby with GBS disease – Preterm labour (<37 weeks) – Prolonged rupture of membranes – Prolonged labour📌Clinical Presentation• Newborns: – Early-onset(within first 7 days): sepsis, pneumonia, meningitis – Late-onset (7days–3 months): may also present, source can be environmental – Red flags: poorfeeding, lethargy, respiratory distress• Pregnant women/adults: – Oftenasymptomatic – May develop UTI,postpartum infection, or rarely, invasive disease📌Investigations• Screening: Not universal in UK — offered basedon risk factors (not on request alone).• Swabs: Vaginal and rectal swabs at 35–37 weeksor 3–5 weeks before expected delivery if indicated• Diagnosis: Culture from blood, urine, or CSF insuspected infection• Antibiotic sensitivity testing is crucial fortargeted therapy📌Management: UKGuidelines (RCOG 2017)• Prevention: – Intrapartum antibiotic prophylaxis (IAP) — IVbenzylpenicillin during labour for women with specific risk factors – No universal screening in the UK —risk-factor-based only – Women with previous baby with GBS disease:offer IAP, or offer late-pregnancy swabbing and treat if positive• Treatment: – Newborns ormothers with confirmed infection: appropriate IV antibiotics (based onsensitivity) – Pregnant/adultinfections: treat with antibiotics per clinical scenario📌Complications &Prognosis• Prompt diagnosis and treatment = generallygood outcome• Severe GBS innewborns: risk of long-term disability (neurological sequelae, developmentaldelay), or mortality• Adults: risk ofendometritis, wound infection, or sepsis 💡UK MSRA Mnemonic:“GBS = Guidelines-Based Screening” (i.e.risk-factor based, not universal) 📎More GBS RevisionResources:📝 Revision Notes: https://www.passthemsra.com/topic/group-b-streptococcus-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/group-b-streptococcus-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/group-b-streptococcus-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/group-b-streptococcus-rapid-quiz/🧪 Quiz Bank: https://www.passthemsra.com/quizzes/group-b-streptococcus/🎓 Full Course: https://www.passthemsra.com/courses/obstetrics-and-gynaecology-for-the-msra/#MSRA #GroupBStrep#GBS #NeonatalSepsis #MSRARevision #Obstetrics #Gynaecology #Paediatrics#PassTheMSRA
