This pilot, randomized, double-blind, placebo-controlled study aims to assess the impact of orally administered probiotic strains, exhibiting in vitro antimicrobial activity against Gardnerella vaginalis and Candida albicans, on vaginal well-being in women without preexisting health conditions. Healthy women (n = 30, aged 19-50) were enrolled and randomly assigned using simple randomization to receive either probiotic or placebo capsules. After excluding dropouts, 26 participants (15 in the probiotic group, 11 in the placebo group) completed the study, undergoing a 3-week intervention. Vaginal well-being was assessed before and after the intervention using self-assessed health on a 5-point Likert scale, along with analysis of the vaginal microbiome by targeting the 16S-ITS-23S rRNA operon region with the Nanopore sequencing platform and MIrROR database. Notably, only the probiotic group exhibited a significant improvement in self-assessed overall gut and vaginal health following the intervention (p = 0.009 and p = 0.003, respectively). Nevertheless, no significant changes were observed in the vaginal bacterial community following the intervention and confirming the vaginal colonization of orally ingested probiotic strains through metagenome sequencing proved challenging. In summary, these findings suggest that while oral probiotics may improve perceived vaginal well-being, their role in modulating the vaginal microbiome in healthy women remains inconclusive. Additional research with a larger sample size is necessary to substantiate the endorsement of oral probiotic consumption for preventing BV or maintaining vaginal health in healthy women.

Lactiplantibacillus plantarum WB4304, L. plantarum WB4305, and Levilactobacillus brevis WB4306, isolated from the traditional fermented food kimchi, exhibited acid and bile salt tolerance and strong adhesion to HT-29 cells, suggesting their suitability for intestinal colonization.

In this study, the anti-acne efficacy and mechanism of extracellular proteins (YTCY-EPs) from W. coagulans YTCY strain are analyzed. The main components of YTCY-EPs, extracted and separated from the fermentation broth, are peptides ranging from 1.51 to 11.44 kDa, accounting for about 80%. Among the peptides identified by LC/MS-MS, YTCY_A-F possess the properties of antimicrobial peptides, while YTCY_1-4 possess antioxidative properties. These peptides have a strong effect on Cutibacterium acnes (C. acnes) and significantly inhibit Staphylococcus aureus. The inhibition rate of biofilm adhesion of YT-EPs to C. acnes reached 50% under the MIC. It was found that YTCY-EPs possess strong antioxidant and anti-inflammatory properties. It can effectively reduce active oxygen nearly 3 times and can reduce the downstream TLR2/NF-κB and MAPKs/AP-1 pathways by regulating the nuclear translocation of NF-κB and AP-1 in vitro. The transcriptional expression of inflammatory cytokines, inflammatory chemokines, and matrix metalloproteinase genes is also regulated, thereby slowing the recruitment of inflammatory cells and the development of inflammation, and increasing keratinocyte mobility. In addition, the expression levels of inflammatory factors and matrix metalloproteinases in the rabbit ears with acne problems that were tested with YTCY-EPs were significantly reduced, and it was obviously observed that the rabbit ear inflammation, acne, and keratinization problems were repaired.
