Background: Early-onset sepsis is a common cause of neonatal mortality and mainly occurs due to the colonized microorganisms in the maternal recto-vaginal area. The present study aimed to evaluate the effects of maternal risk factors on recto-vaginal colonization and transmission rate of micro-flora from mothers to infants. Methods: Upon admission, two samples were obtained from the distal thi...
BACKGROUND Immunoglobulin A (IgA) in maternal milk may protect Gambian infants from early Helicobacter pylori colonization. This study sought evidence that this protection could be due to specific IgA antibodies. METHODS Sixty-five infants were screened from 12 weeks of age with [13C]-urea breath tests. Antibodies in maternal milk were measured to determine total IgA content and to detect spe...
group b streptococcus (gbs) is one of the most important bacteria in the majority of maternal and neonatal infections, such as chorioamnionitis, endometritis, bacteremia, sepsis and meningitis. during pregnancy, gbs screening is one of the recommended strategies that are recommended by center of disease control (cdc). this study was aimed to determine the rectovaginal colonization prevalence am...
OBJECTIVE To test the hypothesis that maternal obesity is an independent risk factor for rectovaginal group B streptococcus (GBS) colonization at term. STUDY DESIGN Retrospective cohort study of consecutive women with singleton term pregnancies admitted in labor at Barnes-Jewish Hospital (2004-2008). Maternal BMI≥30 Kg/m2 (obese) or <30 Kg/m2 (nonobese) defined the two comparison groups. The ...
Background: Group B streptococcus is regarded as a potential factor for adverse outcomes of pregnancy such as preterm birth. Objective: To study the association of maternal vaginal colonization with group B streptococcus (GBS) and preterm labor. Materials and Methods: From April 2005 to May 2006, vaginal culture for GBS were conducted in 101 laboring women with a gestational age of 24-37 weeks ...
BACKGROUND HIV-exposed newborns may be at higher risk of sepsis because of immune system aberrations, impaired maternal antibody transfer and altered exposure to pathogenic bacteria. METHODS We performed a secondary analysis of a study (clinicaltrials.gov, number NCT00136370) conducted between April 2004 and October 2007 in South Africa. We used propensity score matching to evaluate the assoc...
OBJECTIVE Universal screening for colonization by group B streptococcus (GBS) is the recommended strategy to reduce incidence of colonization in newborns and prevent neonatal GBS-related disease. This study was designed to assess maternal anxiety levels about prenatal screening and psychological impact of positive colonization test results. METHODS A total of 71 women who screened positively ...
Background Maternal rectovaginal colonization with group B Streptococcus (GBS) is the most common pathway for GBS disease in mother, fetus, and newborn. This article, the second in a series estimating the burden of GBS, aims to determine the prevalence and serotype distribution of GBS colonizing pregnant women worldwide. Methods We conducted systematic literature reviews (PubMed/Medline, Emba...
© 2002 Canadian Medical Association or its licensors Two forms of group B streptococcal (GBS) infection — early onset and late onset — in infants are well recognized, and the distinctions between them are described in Table 1. Risk factors for GBS infection in general include (a) preterm labour (< 37 weeks’ gestation), (b) prolonged rupture of membranes (≥ 18 hours), (c) maternal fever (tempera...
OBJECTIVES While early-onset neonatal GBS sepsis is positively associated with premature birth and prolonged rupture of membranes, there is debate in the literature as to whether maternal GBS colonization is a predictor of adverse obstetric outcome. This is a critical issue to resolve for appropriate management (expectant vs. interventional management) of the patient presenting with premature r...
