Abstract

Group B streptococcus infection (GBS) is an important cause of perinatal infection. Maternal colonization by GBS can cause amniotic infection and thus fetal infection, sometimes causing fetal death. This infection generally occurs in association with premature rupture of membranes. We present here an infrequent case of GBS chorioamnionitis in full-term gestation with intact amniotic membranes. The curiosity of the case lies in the integrity of the amniotic membranes, the asymptomatic clinical presentation, and the adverse result (term fetal death).

Highlights

  • Streptococcus agalactie is a gram positive, catalase and oxidase negative and optional anaerobic coconut belonging to group B of the Lancefield classification, which is why it is called group B Streptococcus or Group B streptococcus infection (GBS)

Summary

Introduction

Streptococcus agalactie is a gram positive, catalase and oxidase negative and optional anaerobic coconut belonging to group B of the Lancefield classification, which is why it is called group B Streptococcus or GBS. The incidence of early neonatal GBS infection in Spain has decreased by 73% after the implementation of prevention measures, standing at a rate of approximately 0.33% to 0.18% [10]. GBS is an important cause of infection during pregnancy (chorioamnionitis) and in the postpartum period (endometritis), and the data is not conclusive, an association has been reported between vaginal colonization by GBS and premature delivery, premature rupture of membranes (PROM), low weight at birth and intrauterine death [11] [12]. As for chorioamnionitis, it is known to originate from the passage of microorganisms into the amniotic cavity and the fetus This access occurs mainly via the ascending route. We present a case of chorioamnionitis with the result of intrauterine fetal death in full-term gestation in which the pregnant woman had integrity of the amniotic membranes
