BACKGROUND: The human microbiome plays an emerging role in cancer biology, yet its contribution to endometrial cancer (EC) remains poorly defined. This study investigates the microbial composition of the vaginal, rectal, and endometrial sit…

BACKGROUND: Endometrial cancer (EC) is one of the most common malignant tumors in women, and in recent years, the role of gut microbiota in tumorigenesis has gradually gained attention. Previous studies have shown that the gut microbiome is…

OBJECTIVE: Endometrial cancer (EC) is a common gynecologic malignancy globally, but the role of the intratumoral microbiome remains poorly defined. While microbial dysbiosis is increasingly linked to cancer, the composition, function, and c…

BACKGROUND: Candida albicans (C. albicans) is an opportunistic mycopathogen that clinically presents serious challenges due to its ability to cause diverse infections. High mortality rates and increased resistance to antifungals are what ma…

BACKGROUND: The dysbiosis of gut microbiome is known to have a significant impact on the progression of sever acute pancreatitis (SAP). This study intends to investigate the alteration of gut microbiome in SAP patients during hospitalizatio…

BACKGROUND: Culture-negative periprosthetic joint infections (CN-PJIs) represent a critical subtype of PJI, and their high prevalence poses substantial challenges for treatment. CN-PJI is commonly managed utilizing antibiotic combinations, …

BACKGROUND: Premature ovarian insufficiency (POI) is a condition identified by the decline in ovarian function before the age of 40. The treatment of POI patients deserves in-depth research. This study aimed to explore the impacts of probio…

OBJECTIVE: To characterize the reproductive tract microbiota in patients with ovarian chocolate cysts (CC) and adenomyosis (AM) compared to controls (NC), and investigate the in vitro effects of representative differential bacteria on human…

OBJECTIVE: To investigate whether vaginal and endometrial microbiota impact pregnancy outcomes in frozen embryo transfers (FET) during hormone replacement cycles. METHODS: This retrospective cohort study analyzed 51 first-time FET patients…

BACKGROUND: The process of in vitro fertilization-embryo transfer (IVF-ET) induces a maternal supraphysiological estradiol environment during embryo implantation and early development. Estrogen is crucial in modulating the colonization of m…

Bacterial biofilms, often forming on medical devices, can lead to treatment failure due to their increased antimicrobial resistance. Cefepime-avibactam (CFP-AVI) exhibits potent activities against Pseudomonas aeruginosa (P. aeruginosa) and …

BACKGROUND: Endometrial hyperplasia (EH) is a precursor to endometrial cancer, and the role of the microbiome in its development is unclear. RESULTS: The present study investigated the uterine microbiome in patients with benign uterine con…

BACKGROUND: This study investigates the effectiveness of the bacteriophage KZag1 against drug-resistant Klebsiella pneumoniae, aiming to assess its potential as a therapeutic agent. The novelty lies in the characterization of KZag1, a Myovi…

BACKGROUND: Adenomyosis is a commonly observed benign gynecological disease that affects the quality of life and social psychology of women of childbearing age. However, because of the unknown etiology and incidence of adenomyosis, its path…

BACKGROUND: Intrauterine adhesion (IUA) is a frequent acquired endometrial condition, for which there is no effective preventive or treatment. Previous studies have found that vaginal microbiota dysregulation is closely related to endometri…

BACKGROUND: Longevity is one of the most complex phenotypes, and its genetic basis remains unclear. This study aimed to explore the genetic correlation and potential causal association between gut microbiota and longevity. RESULTS: Linkage…

BACKGROUND: Previous reports have demonstrated two thiazolidione derivatives (H2-60 and H2-81) can robustly inhibit the planktonic growth and biofilm formation of S. epidermidis and S. aureus by targeting the histidine kinase YycG. Whereas …

BACKGROUND: Accumulating evidence supports the pivotal role of intestinal flora in irritable bowel syndrome (IBS). Serotonin synthesis by enterochromaffin (EC) cells is influenced by the gut microbiota and has been reported to have an inter…

BACKGROUND: Lactobacillus gasseri OLL2809 can highly induce interleukin (IL)-12 production in immune cells. Even though beneficial properties of this strain for both humans and animals have been reported, the mechanism by which the bacteria…

BACKGROUND: The 7.5 kb cryptic plasmid of Chlamydia trachomatis has been shown to be a virulence factor in animal models, but its significance in humans still remains unknown. The aim of this study was to investigate the prevalence and pote…

BACKGROUND: The human gastrointestinal (GI) tract microbiota is characterised by an abundance of uncultured bacteria most often assigned in phyla Firmicutes and Bacteroidetes. Diversity of this microbiota, even though approached with cultur…
