Comparative genome analysis of Corynebacterium ulcerans Japanese isolates revealed domestically and globally diverse geographical distribution of the organism of different types.

A comparative genome analysis of 106 Japanese *Corynebacterium ulcerans* and *C. ramonii* isolates, alongside 597 global strains, revealed distinct domestic lineages dominated by the rare ST337 type, unique regional MLST distributions, and evidence of zoonotic transmission linked to toxin-encoding prophages.

Secretome analysis of Bacillus toyonensis Bto_UNVM-42 reveals extracellular pesticidal protein homologs and enzymes consistent with its nematicidal activity.

This study utilizes LC-MS/MS secretome analysis to demonstrate that *Bacillus toyonensis* Bto_UNVM-42 secretes pesticidal protein homologs and degradative enzymes, providing proteomic evidence that extracellular components contribute to its nematicidal activity and challenging the traditional view of these proteins as solely intracellular.

Ecological Role of the Heterotrophic Protist Aurantiochytrium (Labyrinthulomycetes) as a Key Consumer of Viral-Induced Dissolved Organic Matter Following the Lysis of the Red Tide-forming Microalga Heterosigma akashiwo

This study demonstrates that the heterotrophic protist *Aurantiochytrium* thrives on viral-induced dissolved organic matter released during the lysis of the red tide alga *Heterosigma akashiwo*, identifying it as a key consumer that facilitates carbon cycling and nutrient transfer in coastal microbial food webs following harmful algal blooms.

Engineered Lactate Catabolizing Probiotics Reveal Timescale Dependent Microbiome-Host Metabolic Coupling

This study demonstrates that engineered *Bacillus subtilis* probiotics expressing lactate oxidase can acutely improve host energy balance and sepsis survival by rewiring microbiome metabolism toward anabolic processes, but these beneficial effects fail to persist chronically due to homeostatic compensation, highlighting a clear timescale-dependent limit to gut-centric metabolic therapies.

Comparative analysis of flavivirus sfRNA dynamics and secondary structure

This study utilizes digital droplet PCR and SHAPE-MaP to compare the secondary structures of subgenomic flavivirus RNAs (sfRNAs) from four mosquito-borne flaviviruses in vitro and within infected cells, revealing largely similar structures with minor, consistent differences that suggest sfRNAs engage in only few, transient, or base-paired interactions with host and viral factors during infection.

Gel-forming fibres differentially modulate inulin fermentation: A comparison of psyllium and methylcellulose in in vitro colonic models

This study demonstrates that psyllium, unlike methylcellulose, enhances inulin fermentation and metabolic health benefits by forming a gel matrix that facilitates bacterial penetration and access to substrates, thereby accelerating gas production, enriching polysaccharide-degrading microbes, and stimulating gut hormone secretion.

A joint Bayesian framework for modeling Plasmodium vivax transmission

This study introduces a joint Bayesian latent-variable model that integrates parasite density, gametocyte density, and mosquito infectivity to quantify their interlinked relationships and measurement uncertainties in *Plasmodium vivax* transmission, revealing that while gametocyte density is the primary driver of infectivity, asexual parasite density provides significant additional predictive information.

Quorum sensing and capsule expression enable subpopulation evasion of phage killing in Escherichia coli ST131: Implications for targeted therapy

This study demonstrates that Escherichia coli ST131 evades phage killing in urine through quorum sensing and capsule expression, but a rationalized therapy combining depolymerase-encoding phages, multi-receptor targeting, specific carbon sources, and simulated bladder washes can effectively overcome these resistance mechanisms to sterilize bacterial cultures.

Proviral dynamics and HIV-1C viral diversity in the context of HIV-TB co-infection

This study demonstrates that while tuberculosis co-infection does not significantly alter HIV-1C proviral loads in ART-naive individuals, it is associated with distinct immune activation patterns, increased viral diversity, and a higher prevalence of drug resistance mutations, underscoring the critical need for comprehensive baseline screening and multi-compartment surveillance in TB-endemic settings.
