Alternating High‐Fat and Polysaccharide Diets Modulates Gut Phage‐Bacterial Interplay

Advanced Science, EarlyView.
This study reveals how alternating high‐fat and polysaccharide diets reshape the human gut virome and enhance phage‐bacteria interactions. Using large‐scale metagenomic meta‐analysis and a time‐resolved mouse model, the authors show that diets strongly modulate phage abundance, lifestyle, and gene exchange, offering new insights into nutrition‐guided ...

Vaginal pH measured in vivo: lactobacilli determine pH and lactic acid concentration

BMC Microbiology, 2019
Background Lactic acid (protonated lactate) has broad antimicrobial activity. Vaginal lactobacilli produce lactic acid, and are known to confer protection against reproductive tract infections when they are predominant in the vaginal microbiota.

Multicohort Validation of Gut Microbiome Signatures for Cholangiocarcinoma Diagnosis and Functional Characterization of Bifidobacterium Pseudocatenulatum

Advanced Science, EarlyView.
This study analyzes gut bacteria in cholangiocarcinoma patients, revealing distinct microbial signatures that enable accurate disease detection. Species‐based diagnostic models achieved over 98% accuracy in identifying cholangiocarcinoma and distinguished it from other liver diseases. The research demonstrates that specific beneficial bacteria suppress

Oncolytic Probiotics with Molecular Pili for Solid Tumor Therapy

Advanced Science, EarlyView.
This study identifies Lactobacillus rhamnosus as an intrinsic oncolytic agent that triggers tumor metabolic collapse via calcium‐dependent ROS bursts. By chemically anchoring collagen‐targeting “molecular pili” to the bacterial surface, the engineered non‐transgenic probiotic (LR@MP) achieves targeted colonization and potent solid tumor suppression ...

Dual‐Key Genetic Circuit Enables Stable and Self‐Regulated Engineered Bacteria for the Treatment of Ulcerative Colitis

Advanced Science, EarlyView.
A self‐regulated Escherichia coli Nissle 1917 strain equipped with a dual‐key genetic circuit achieved antibiotic‐free stability and programmable lysis for therapeutic protein delivery. By co‐expressing an IL‐2 mutant and Amuc_1100, the engineered bacteria restored immune balance and epithelial integrity, providing a safe and precise approach for ...
