OBJECTIVE The study aimed to assess whether maternal colonization with Staphylococcus aureus during pregnancy or at delivery was associated with infant staphylococcal colonization. METHODS For this prospective cohort study, women were enrolled at 34 to 37 weeks of gestation between 2007 and 2009. Nasal and vaginal swabs for culture were obtained at enrollment; nasal swabs were obtained from w...

background: microorganisms that cause early neonatal sepsis are usually already colonized rectovaginal area in mothers. the most common of these organisms is group b streptococci (gbs) and intestinal gram-negative bacteria mostly escherichia coli (e.coli). the use of prophylactic antibiotics against gbs has increased in recent years. this study aimed to determine the current situation and frequ...

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 ...

The objective of this study was to determine the prevalence of maternal group B Streptococcal (GBS) colonization and compare risk factor data related to GBS colonization. A prospective surveillance study of 598 pregnant women was conducted in two socioeconomically diverse maternity hospitals in Ribeirão Preto, Brazil between June and October 1999. Swabs from the lower vagina were obtained betwe...

The gastrointestinal microbiota plays an important role in maintaining host health by preventing the colonization of pathogens, fermenting dietary compounds, and maintaining normal mucosal immunity. Particularly in early life, the composition of the microbiota profoundly influences the development and maturation of the gastrointestinal tract (GIT) mucosa, which may affect health in later life. ...

Mammalian body surfaces are inhabited by vast numbers of microbes, the commensal microbiota, which help the host to digest food, provide nutrients, and mature its immune system. For a long time, postnatal colonization was believed to be the main stimulus for microbial-induced immune development. Using a model of reversible colonization of germ-free mice during gestation, we recently showed that...

BACKGROUND Staphylococcus aureus infections are increasing among pregnant and postpartum women and neonates, but risk factors for S. aureus colonization in pregnancy and the association between maternal colonization and infant infections are not well defined. We sought to identify risk factors for maternal S. aureus rectovaginal colonization and assess colonization as a risk factor for infectio...

BACKGROUND Preterm infants are at high risk for extended spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E) sepsis and neonatal intensive care unit (NICU) outbreaks. Maternal colonization with ESBL-E may be precursory to maternal-neonatal transmission. However, there is no consensus regarding surveillance of pregnant women for ESBL-E colonization. AIM To identify pairs of mothers a...

Background Preterm birth complications are the leading cause of deaths among children <5 years of age. Studies have suggested that group B Streptococcus (GBS) maternal rectovaginal colonization during pregnancy may be a risk factor for preterm delivery. This article is the fifth of 11 in a series. We aimed to assess the association between GBS maternal colonization and preterm birth in order to...

Background The maternal and infant microbiome may influence infant cardiovascular risk through immune programming. The maternal vagino-enteric microbiome is often sampled for group B streptococcus (GBS) colonization during pregnancy. Our aim was to investigate the association between maternal GBS colonization, intrapartum antibiotics, antenatal pet exposure and infant aortic intima-media thickn...
