Novel Insights on Group B Streptococcus in Pregnancy

Area of Science:

• Obstetrics and Gynecology
• Neonatal Health
• Infectious Diseases

Background:

• Group B Streptococcus (GBS) frequently colonizes the genital and gastrointestinal tracts.
• While often asymptomatic in pregnant individuals, GBS can lead to significant infectious morbidity in both the parent and newborn.
• Despite a 3-decade decrease in invasive GBS disease, it remains a public health issue.

Purpose of the Study:

• To review the pathophysiology, morbidity, and management guidelines of Group B Streptococcus (GBS).
• To summarize current research on GBS, including novel testing and vaccination strategies.
• To identify barriers hindering the update and implementation of GBS management guidelines.

Main Methods:

• Literature review of Group B Streptococcus (GBS) pathophysiology, clinical presentation, and epidemiology.
• Analysis of current management guidelines and clinical algorithms for GBS.
• Synthesis of ongoing research and exploration of potential future interventions like diagnostics and vaccines.

Main Results:

• Invasive GBS disease prevalence has significantly declined over 30 years.
• Standardized clinical algorithms are in place, yet GBS disease persists as a public health concern.
• Novel diagnostic tests and maternal vaccination are under investigation but face implementation challenges.

Conclusions:

• Group B Streptococcus (GBS) remains a critical consideration in maternal and neonatal health.
• Despite advances, barriers to updating and implementing GBS guidelines and interventions persist.
• Continued research and strategic implementation are necessary to further mitigate GBS-related morbidity.
