Tubal factor infertility (TFI) accounts for more than 30% of the cases of female infertility and mostly resides from an inflammatory process triggered by an infection. Clinical appearances largely differ, and very often infections are not recognized or remain completely asymptomatic over time. Here, we characterized the microbial pattern in females diagnosed with infectious infertility (ININF) in comparison to females with non-infectious infertility (nININF), female sex workers (FSW) and healthy controls (fertile)...

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: Some sexually transmitted infectious agents, such as Chlamydia trachomatis and Herpes simplex, cause local inflammation, and could contribute to Human Papillomavirus (HPV) and cervical lesion progression. Thus, the aim of this study was to determine any association between the presence of microorganisms of gynecological importance, sexual behavior, clinical and demographical variables to the development and progress of cervical lesions. METHODS: One hundred and thirty-two women between 14 and 78 years and living at Vitória da Conquista, Bahia, Brazil, were included (62 individuals with cervical lesions and 70 without lesions)...

The cervical microbiota composition and diversity of HIV-positive women in the postpartum period is unknown. Using a high-throughput bacterial 16S rRNA gene sequencing, we identified four community state types (CSTs). CST III (Lactobacillusdominant) and CST IV (IV-A, IV-B.1, IV-B.2; high-diversity) were found in 41% and 59% of samples, respectively. We did not find association of any CST to postpartum period (six or twelve months), HPV infection or cytology (normal or lesion). However, five bacterial genera were associated with cervical lesions (Gardnerella, Aerococcus, Schlegelella, Moryella and Bifidobacterium), with significant odds ratio (OR) of 40 (2...

Study of the probiotic potential of microorganisms isolated from fermented foods has been increasing, especially studies related to lactobacilli. In intestinal models, lactobacilli have demonstrated beneficial properties, such as anti-inflammatory activity and increased antibody production, but the molecular mechanisms involving probiotic and antagonistic action as well as their effect on human vaginal cells have not yet been fully elucidated. The aim of this study was to evaluate the functional and antagonistic properties of three strains of lactobacilli isolated from cocoa fermentation (Lactobacillus fermentum 5...

Changes in the skin microbiome have been shown to promote cutaneous inflammation. The skin microbiome of patients with chronic plaque type psoriasis was analysed before and after treatment with narrowband ultraviolet B (UVB). Swab samples of the microbiome were taken from lesional and non-lesional skin of 26 patients. Microbiotas were characterized by sequencing 16S rRNA bacterial genes on the Illumina MiSeq platform. Lesional skin microbiome diversity correlated with psoriasis severity (measured with the Psoriasis Area and Severity Index; PASI)...

Poly(ɛ-caprolactone) (PCL) intra-vaginal matrices were produced for local delivery of a combination of antibacterials, by rapidly cooling a mixture of drug powders dispersed in PCL solution. Matrices loaded with different combinations of metronidazole (10, 15 and 20% w/w) and doxycycline (10% w/w), were evaluated in vitro for release behavior and antibacterial activity. Rapid 'burst release' of 8-15% of the doxycycline content and 31-37% of the metronidazole content occurred within 24 h when matrices were immersed in simulated vaginal fluid (SVF) at 37°C...

PURPOSE OF REVIEW: HIV prevention approaches that women can use and control are a priority. Results from topical and oral preexposure prophylaxis (PrEP) HIV prevention trials have produced inconsistent results in women. One of the main behavioural factors impacting effectiveness of PrEP has been suboptimal adherence. In this review, we examine biological factors that modulate topical PrEP efficacy, with particular focus on the vaginal microbiome. RECENT FINDINGS: Genital inflammation is an independent risk factor for HIV acquisition in women...

Bacterial vaginosis is the most prevalent cause of abnormal vaginal discharge in women of childbearing age. It can have a major impact on quality of life and psychological wellbeing if frequently recurrent and strongly symptomatic. The use of molecular techniques to study the vaginal microbiome is increasing our understanding of the dynamic changes in flora that occur in health and disease. It might soon be possible to separate Gardnerella into different pathogenic and non-pathogenic species. Many groups are studying compounds that can disrupt the biofilm which is dominated by Gardnerella and Atopobium vaginae...

Young African females are at increased risk of HIV acquisition, and genital inflammation or the vaginal microbiome may contribute to this risk. We studied these factors in 168 HIV negative South African adolescent women aged 16-22 years. Unsupervised clustering of 16S rRNA gene sequences revealed three clusters (subtypes), one of which was strongly associated with genital inflammation. In a multivariate model, microbiome compositional subtype and hormonal contraception were significantly associated with genital inflammation...

Background: Bacterial vaginosis is the most frequent condition associated to the vaginal microbiota imbalance, affecting about the 40-50% of women in the world. Even if antibiotics are effcetive for bacterial vaginosis treatment a long-term recurrence rates, higher than 70%, is recorded. Lactoferrin is an iron-binding glycoprotein with bacteriostatic and bactericidal properties. It owns the ability to protect the host against infection, by binding and regulating the iron needed for the bacterial proliferation...

Lactobacillus rhamnosus DSM 14870 and Lactobacillus gasseri DSM 14869 were previously isolated from the vaginal epithelial cells (VEC) of healthy women and selected for the development of the vaginal EcoVag(®) probiotic capsules. EcoVag(®) was subsequently shown to provide long-term cure and reduce relapse of bacterial vaginosis (BV) as an adjunct to antibiotic therapy. To identify genes potentially involved in probiotic activity, we performed genome sequencing and characterization of the two strains. The complete genome analysis of both strains revealed the presence of genes encoding functions related to adhesion, exopolysaccharide (EPS) biosynthesis, antimicrobial activity, and CRISPR adaptive immunity but absence of antibiotic resistance genes...

In cross-sectional studies increased vaginal bacterial diversity has been associated with vaginal inflammation which can be detrimental for health. We describe longitudinal changes at 5 visits over 8 weeks in vaginal microbiota and immune mediators in African women. Women (N = 40) with a normal Nugent score at all visits had a stable lactobacilli dominated microbiota with prevailing Lactobacillus iners. Presence of prostate-specific antigen (proxy for recent sex) and being amenorrhoeic (due to progestin-injectable use), but not recent vaginal cleansing, were significantly associated with microbiota diversity and inflammation (controlled for menstrual cycle and other confounders)...

Two basic questions about lysozyme activities on the selected microorganisms were investigated, namely whether lysozyme inhibits biofilm production and which concentrations of the enzyme have the ability to change the natural biofilm producing capacity of different strains of Staphylococcus aureus (methicillin sensitive and resistant), Streptococcus pyogenes, Pseudomonas aeruginosa, and Gardnerella vaginalis. The effect of lysozyme on biofilm formation capacities of 16 strains of selected microorganisms was investigated, whereby four testing replicates have been performed in vitro using the Test Tube method, and the potential of lysozyme to change biofilm forming capacities depending on its concentration, species, and strains of microorganisms is demonstrated...
