HPV and Chlamydia trachomatis are the most common causes of sexually transmitted diseases worldwide. Most infections are asymptomatic and left untreated lead to severe reproductive tract sequelae such as cervical cancer and infertility. Interestingly, C. trachomatis may also increase the susceptibility to HPV infection as well as contribute to viral persistence. Recently, a growing body of evidence has suggested that the composition of the cervico-vaginal microbiota plays a key role in the susceptibility and outcome of genital infections caused by several pathogens, including HPV and C...

The bacterial community found in the vagina is an important determinant of a woman's health and disease. A healthy vaginal microbiota is associated with a lower species richness and high proportions of one of a number of different Lactobacillus spp.. When disrupted the resulting abnormal vaginal microbiota is associated with a number of disease states and poor pregnancy outcomes. Studies up until now have concentrated on relatively small numbers of American and European populations which may not capture the full complexity of the community, nor adequately predict what constitutes a healthy microbiota in all populations...

BACKGROUND: Over recent years, a growing interest has developed in microbiota and in the concept of maintaining a special balance between Lactobacillus and other bacteria species in order to promote women's well-being. The aim of our study was to confirm that vaginal Lactobacilli long-lasting implementation in women with HPV-infections and concomitant bacterial vaginosis or vaginitis might be able to help in solving the viral infection, by re-establishing the original eubiosis. METHODS: A total of 117 women affected by bacterial vaginosis or vaginitis with concomitant HPV-infections were enrolled at Department of Gynecological Obstetrics and Urological Sciences, La Sapienza University, Rome, Italy between February 2015 and March 2016...

For the development of disease prevention and intervention strategies, a better understanding of the dynamics and interactions within cervical bacterial communities in both healthy cows and cows with metritis is required. Understanding the complexity and ecology of microorganisms in the vagina of dairy cows with metritis and during different physiological phases is critical for developing strategies to balance microorganism content. To gain deeper insight into fluctuations within the cervical microbiota, swab samples were collected from 40 Holstein dairy cows, and16S rDNA amplicon sequencing was used to analyze cervical bacterial diversity...

Vaginal microbiota is an important early source of bacterial colonization for newborns. However, only a few small studies have investigated the composition of vaginal microbiota during labor. In this work, we analyzed vaginal swabs collected at 36 weeks gestation and at the onset of labor from 256 women participating in a randomized placebo-controlled study of probiotic supplementation for the prevention of atopic dermatitis in offspring. Although individuals' vaginal microbiota was stable over time, several bacterial families, which are characteristic of mixed community state type (CST) IV, were overrepresented in vaginal swabs sampled at labor...

Background: Due to chemotherapy and estrogen deprivation therapy, genitourinary syndrome of menopause is a common condition in breast cancer patients. We aimed to determine the effect of an orally administered Lactobacillus preparation on the vaginal microbiota in breast cancer patients. Methods: Postmenopausal breast cancer patients receiving chemotherapy, with vaginal atrophy and an intermediate vaginal microbiota (Nugent score 4-6), were either randomized to the intervention group receiving probiotic capsules of 4 Lactobacillus species or to the control group receiving placebo twice daily for 2 weeks...

Cesarean (C-section) delivery, recently shown to cause excess weight gain in mice, perturbs human neonatal gut microbiota development due to the lack of natural mother-to-newborn transfer of microbes. Neonates excrete first the in-utero intestinal content (referred to as meconium) hours after birth, followed by intestinal contents reflective of extra-uterine exposure (referred to as transition stool) 2 to 3 days after birth. It is not clear when the effect of C-section on the neonatal gut microbiota emerges...

The high incidence of vulvo-vaginal candidiasis, combined with the growing problems about azole resistance and toxicity of antifungal drugs, highlights the need for the development of new effective strategies for the treatment of this condition. In this context, natural compounds represent promising alternatives. The cyanobacterium Spirulina platensis, a blue-green alga, exhibits antimicrobial activities against several microorganisms. Nevertheless, only few data about the antifungal properties of Spirulina platensis are available and its potential toxic effects have not been largely investigated...

The study of the vaginal microbiota using the "culturomics concept" allowed us to isolate, from the vaginal swab of an asymptomatic 20-year-old woman who had sexual relations with another woman with bacterial vaginosis, an unknown Gram-positive anaerobic coccus-shaped bacterium that was designated strain Marseille-P2951T and characterized using taxono-genomics. Strain Marseille-P2951T is non-motile and non-spore forming and exhibits catalase and oxidase activities. Its 16S rRNA gene-based identification showed 98...

Preterm birth is a leading cause of global neonate mortality. Hospitalization costs associated with preterm deliveries present a huge economic burden. Existing physical/biochemical markers for predicting preterm birth risk are mostly suited for application at mid/late pregnancy stages, thereby leaving very short time (between diagnosis and delivery) for adopting appropriate intervention strategies. Recent studies indicating correlations between pre/full-term delivery and the composition of vaginal microbiota in pregnant women have opened new diagnostic possibilities...

BACKGROUND: Vulvovaginal candidiasis (VVC) is estimated to be the second most common form of infection after bacterial vaginosis. The ability of probiotics in maintaining and recovering the normal vaginal microbiota, and their potential ability to resist Candidas give rise to the concept of using probiotics for the treatment of VVC. OBJECTIVES: To assess the effectiveness and safety of probiotics for the treatment of vulvovaginal candidiasis in non-pregnant women...

BACKGROUND: Provision of routine iron supplements to prevent anaemia could increase the risk for lower genital tract infections as virulence of some pathogens depends on iron availability. This trial in Burkina Faso assessed whether weekly periconceptional iron supplementation increased the risk of lower genital tract infection in young non-pregnant and pregnant women. METHODS: Genital tract infections were assessed within a double blind, controlled, non-inferiority trial of malaria risk among nulliparous women, randomised to receive either iron and folic acid or folic acid alone, weekly, under direct observation for 18 months...

Conjugative plasmids represent major reservoirs for horizontal transmission of antibiotic resistance (AR) and virulence genes. Our knowledge about the ecology and persistence of these plasmids in the gut microbiota remains limited. The IncF plasmids are the most widespread in clinical samples and in healthy humans. Therefore, the main aim is to study their ecology and association with the developing gut microbiota. Using a longitudinal (2, 10, 30 and 90 days) cohort of full-term infants, we investigated the transmission and persistence of IncFIA and IncFIB plasmids...

Mode of delivery (vaginal or cesarean section) is thought to affect gut microbiota, which in turn may affect psychological well-being. As such, mode of delivery is potentially a modifiable factor for psychological well-being. Here we examined the association of mode of delivery with child and adolescent psychological well-being. We used multivariable linear regression in a population-representative Hong Kong Chinese birth cohort, "Children of 1997," to examine the adjusted associations of mode of delivery with behavioral problems assessed from parent-reported Rutter score at ~7 (n = 6294) and ~11 years (n = 5598), self-esteem assessed from self-reported Culture-Free Self-Esteem Inventory score at ~11 years (n = 6937) and depressive symptoms assessed from self-reported Patient Health Questionnaire-9 score at ~13 years (n = 5797)...
