The colonization of the gut with microbes in early life is critical to the developing newborn immune system, metabolic function and potentially future health. Maternal microbes are transmitted to offspring during childbirth, representing a key step in the colonization of the infant gut. Studies of infant meconium suggest that bacteria are present in the foetal gut prior to birth, meaning that colonization could occur prenatally. Animal studies have shown that prenatal transmission of microbes to the foetus is possible, and physiological changes observed in pregnant mothers indicate that in utero transfer is likely in humans as well...

Life-threatening infection in neonates due to Group B Streptococcus (GBS) is preventable by screening near-term pregnant women and treatment at delivery. 295 vaginal-rectal swabs were collected from women attending antepartum clinics in Calgary. GBS colonization was detected by the standard culture method (Strep B Carrot broth subbed to blood agar with a neomycin disk), and compared to recovery using Strep Group B Broth (Dalynn Biologicals) subbed to StrepB Select chromagar (CA) (Bio-Rad Laboratories), and the Fast Track Diagnostics GBS real-time PCR (qPCR) assay (Phoenix Airmid Biomedical Corp...

BACKGROUND: Vulvovaginal candidiasis (VVC) is a vulvovaginitis commonly diagnosed in gynecology care. In recent years, the taxonomy of the most important pathogenic Candida species, such as Candida albicans have undergone significant changes. AIMS: This study examined the prevalence of C. albicans, Candida africana, and Candida dubliniensis in vaginal specimens from 210 pregnant women suffering from vulvovaginitis or having asymptomatic colonization. METHODS: Phenotypic and molecular methods were used for the identification of the species...

Maternal colonization with group B Streptococcus (GBS) during pregnancy increases the risk of neonatal infection by vertical transmission. However, it remains unclear whether treating all colonized women during labor exposes a large number of their neonates to possible adverse effects without benefit. We performed a meta-analysis to assess the effect of intrapartum antibiotic prophylaxis on neonatal adverse outcomes. We identified studies by searching several English and Chinese electronic databases and reviewing relevant articles...

OBJECTIVE: Vaginal Candida colonization is common during pregnancy. Vaginal Candida may transmit vertically to the mouth of newborns during labor. The aim of this study was to assess and compare oral Candida colonization between vaginally born newborns and cesarean-born newborns and to investigate the association of the mother's vaginal and oral Candida colonization and the newborn's oral colonization at the time of delivery. STUDY DESIGN: Culture swabs were collected from the oral and vaginal mucosae of 100 pregnant women and from the oral mucosa of their 100 full-term newborns...

OBJECTIVES: Because few studies have been conducted on group B Streptococcus (GBS) in Nigeria, we sought to estimate GBS colonization and transmission frequencies for 500 women and their newborns and identify risk factors for both outcomes. METHODS: GBS strains were characterized for antibiotic susceptibilities, capsule (cps) genotype, pilus island profile, and multilocus sequence type (ST). RESULTS: In all, 171 (34.2%) mothers and 95 (19...

In Mongolia, diagnostic tests for the detection of the sexually transmitted mycoplasmas, ureaplasmas, Herpes simplex virus (HSV), and cytomegalovirus (CMV) are currently not routinely used in clinical settings and the frequency of these STIs are enigmatic. The prevalence of these STI pathogens were prospectively evaluated among 200 Mongolian pregnant women and their newborns and correlated with pregnancy outcome. TaqMan PCRs were used to detect bacterial and viral STI pathogens in pre-birth vaginal swabs of the pregnant women and in oral swabs of their newborns...

Group B streptococcus (GBS) is a leading cause of neonatal sepsis, with the highest incidence (1.3 per 1000 live births) reported from Africa. Although the incidence of invasive GBS disease is reportedly low in South Asia, there is disconnect between prevalence of maternal recto-vaginal colonization and the incidence of early-onset disease (EOD). This is possibly due to case-ascertainment biases that omit investigation of newborns dying on day-0 of life, which accounts for >90% of EOD. Furthermore, GBS is associated with approximately 15% of all infection related stillbirths...

OBJECTIVE: To assess the urologic and obstetric outcomes during and after pregnancy following urinary diversion (UD) performed during childhood or adolescence. MATERIALS AND METHODS: From our UD database, we identified 25 women who became pregnant between 1981 and 2013. Reasons for UD were neurogenic bladder, exstrophy, trauma, sinus urogenitalis, and interstitial cystitis. Seventeen had continent cutaneous diversion, 4 had continent anal diversion, and 4 had colonic conduit...

BACKGROUND: Probiotics can alter the colonic microbiota and might improve bowel function. OBJECTIVES: The aim of this study was to evaluate the effect of the consumption of yogurt, enriched with Bifidobacterium and Lactobacillus 4.8 × 10(10) (CFU) on the symptoms of constipated pregnant women. MATERIALS AND METHODS: This triple-blind randomized controlled trial was conducted on 60 constipated pregnant women who were diagnosed by the ROME III criteria in Tabriz, Iran from December 2014 to July 2015...

BACKGROUND: Candidiasis, the infection caused by Candida albicans, is one of the most common infections of the oral cavity in humans. Candidiasis causes irritation and is known for its carcinogenic effects. Thus, it is important to recognize the predisposing factors for this opportunistic infection. Several previous studies have demonstrated an increased frequency of vaginal candidiasis in relation to oral contraceptive consumption. OBJECTIVES: Only a few studies on the relation between oral contraceptives and oral candidiasis have been previously conducted...

BACKGROUND: Recent studies suggest that placenta may harbour a unique microbiome that may have origin in maternal oral microbiome. Although the major physiological and hormonal adjustments observed in pregnant women lead to biochemical and microbiological modifications of the oral environment, very few studies evaluated the changes suffered by the oral microbiota throughout pregnancy. So, the aim of our study was to evaluate oral yeast colonization throughout pregnancy and to compare it with non-pregnant women...

BACKGROUND: While the use of antibiotic prophylaxis is clearly advantageous to prevent streptococcal infection, it alters the composition of the gut microbiota in mothers and infants. Enterococcus faecium L3 is one of the best studied probiotic strains and shows strong antagonistic activity against Streptococcus agalactiae due to the production of bacteriocins able to inhibit common gut and vaginal pathogens. METHODS: We tested an L3-based probiotic formula (iNatal®) on 127 pregnant women attending our gynaecological unit in 2015...

BACKGROUND: Microcephaly has become a major public health problem in Brazil. The total number of newborns with microcephaly was reported to be >4000 in June 2016. Studies suggest that Zika Virus is a major cause of new microcephaly cases in Brazil. Inside the uterus, the foetus is surrounded by the Amniotic Fluid, a proximal fluid that contains foetal and maternal cells as well as microorganisms and where Zika Virus was already found. CASE PRESENTATION: A previous study reported the presence of the Zika Virus in the amniotic fluid (collected in the 28th gestational week) of two pregnant women carrying microcephaly foetuses in Brazil...

OBJECTIVE: To review the evidence in the literature and to provide recommendations on the management of pregnant women in labour for the prevention of early-onset neonatal group B streptococcal disease. The key revisions in this updated guideline include changed recommendations for regimens for antibiotic prophylaxis, susceptibility testing, and management of women with pre-labour rupture of membranes. OUTCOMES: Maternal outcomes evaluated included exposure to antibiotics in pregnancy and labour and complications related to antibiotic use...

In the late 1930s, it was discovered that liver and yeast extracts can be used to correct certain cases of megaloblastic anemia in pregnancy. The factor responsible for this was isolated from spinach leaves in the 1940s, and referred to as folate, a term derived from the Latin word folium for leaf. Folate is considered an essential nutrient for human beings. Folic acid, the synthetic form of the vitamin, is used in dietary supplements, medicines and fortified foods. Since the 1980s, it has been recommended that women who plan to become pregnant and pregnant women during the first trimester of pregnancy take folic acid supplements...
