Streptococci and the genital tract

D Rowen

    International Journal of STD & AIDS
    |March 1, 1993
    PubMed
    Summary

    Group B Streptococcus (GBS) colonization is common in women, posing risks for neonatal sepsis and preterm labor. Intrapartum chemoprophylaxis effectively prevents early-onset GBS disease in newborns.

    Area of Science:

    • Obstetrics and Gynecology
    • Infectious Diseases
    • Neonatology

    Background:

    • Lancefield Group B Streptococcus (GBS) causes maternal sepsis and neonatal infections.
    • GBS colonization rates in women range from 4-18%, with higher prevalence in healthcare settings, increasing nosocomial transmission risk.
    • Lancefield Group A Streptococcus (GAS) causes vulvo-vaginitis, with lower genital tract prevalence than GBS but higher symptomatic rates.

    Discussion:

    • GBS vaginal carriage can lead to complications like amnionitis and chorioamnionitis, potentially causing preterm labor.
    • GBS infections in male genitalia have also been documented.
    • While symptomatic GAS infections are more common, GBS poses significant risks, especially to neonates.

    Key Insights:

    • Intrapartum chemoprophylaxis is proven to prevent early-onset GBS neonatal disease.
    • High GBS carriage rates highlight the importance of screening and prevention strategies.
    • Penicillin is generally effective against GAS, but optimal treatment regimens, especially during pregnancy, require further determination.

    Outlook:

    • Further research is needed to establish optimal drug regimens for GBS and GAS treatment during pregnancy.
    • Continued investigation into the link between GBS chorioamnionitis and preterm labor is warranted.
    • Strategies to mitigate nosocomial transmission of GBS in healthcare settings are crucial.
