Microbiology explores the invisible world of tiny life forms that shape our health, environment, and even the air we breathe. From bacteria and viruses to fungi and parasites, this field investigates how these microscopic organisms interact with us and each other, driving everything from disease outbreaks to beneficial fermentation processes. Understanding them is crucial for developing new medicines, improving food safety, and combating global health challenges.

At Gist.Science, we make the latest discoveries in this dynamic field accessible to everyone. We process every new preprint uploaded to bioRxiv in this category, transforming dense academic findings into both clear, plain-language explanations and detailed technical summaries. This ensures that whether you are a student, a researcher, or simply curious, you can grasp the significance of cutting-edge science without getting lost in jargon.

Below are the most recent papers in microbiology, curated and summarized directly from the bioRxiv server to keep you at the forefront of discovery.

DSF signalling integrates c-di-GMP and σ54 pathways with metabolic reprogramming to control Stenotrophomonas maltophilia pathogenicity and antibiotic resistance

This study reveals that in *Stenotrophomonas maltophilia*, DSF-mediated quorum sensing integrates c-di-GMP signaling, the σ54 transcriptional pathway, and metabolic reprogramming to orchestrate the switch between biofilm and motile lifestyles while modulating antibiotic resistance.

HIV lymphoid tissue fibrosis occurs in the earliest stages of acute HIV infection and is associated with macrophage-derived TGF-β

This study reveals that HIV-induced lymphoid tissue fibrosis occurs during the earliest stages of acute infection and is driven by macrophage-derived TGF-β, suggesting that immediate antiretroviral therapy may be insufficient to prevent or reverse this structural damage.

Chromid-like secondary replicons as key sites of biosynthetic gene clusters in Ktedonobacteria

This study reveals that Ktedonobacteria, a widespread soil-dwelling bacterial class, possess highly diverse biosynthetic gene clusters primarily housed on recurrent chromid-like secondary replicons, significantly expanding our understanding of soil microbial chemical diversity and genome architecture.

Not all West Nile virus lineages behave alike: vector competence and minimum infectious dose differences between lineages 1 and 2

This study demonstrates that West Nile virus lineage 2 exhibits higher transmission efficiency and requires lower infectious doses than lineage 1 across three mosquito species, with *Culex torrentium* identified as a highly competent vector despite its limited prior research.

Metabolite profiles distinguish exposure to Dengue and Zika flaviviruses in human induced pluripotent stem cells (hiPSCs)

This study demonstrates that untargeted metabolomics of human induced pluripotent stem cells can distinguish between Dengue and Zika virus infections by identifying virus-specific metabolic signatures and reveals that modulating tryptophan metabolism regulates viral replication, offering a promising complementary diagnostic and therapeutic strategy.

Prevalent Gut Phages Encode Modular Adhesins Mediating Epithelial Binding and Endoplasmic Reticulum Trafficking

This study reveals that prevalent human gut phages encode modular Ig-like adhesins that mediate specific binding to and non-degradative trafficking of epithelial cells, highlighting widespread phage-human interactions with significant implications for phage therapy.

Optimizing histatin 5: Effects of K13 and K17 substitutions on proteolytic stability and antifungal activity

This study demonstrates that substituting lysine residues at positions 13 and 17 in histatin 5, particularly with arginine at K13 and tryptophan at K17, significantly enhances the peptide's proteolytic stability against *Candida albicans* proteases and salivary enzymes while improving its antifungal activity and biofilm inhibition capabilities.

Molecular analysis of Lancefield group C/G streptococci causing human infections in Sheffield, UK.

This study presents the first comprehensive genomic analysis of Lancefield group C/G streptococci in Sheffield, UK, revealing a highly diverse *Streptococcus dysgalactiae* subsp. *equisimilis* population with significant antimicrobial resistance, the presence of a globally virulent lineage, and evidence of long-term host persistence, thereby highlighting the urgent need for enhanced national genomic surveillance.

The Stenotrophomonas maltophilia MntR miniregulon includes novel extracytoplasmic components and affects replication in Acanthamoeba castellanii phagosomes

This study characterizes a novel MntR-controlled miniregulon in *Stenotrophomonas maltophilia* that integrates conserved transporters with unique extracytoplasmic components to coordinate manganese homeostasis and iron interplay, thereby enabling the bacterium to prevent metal toxicity and replicate within *Acanthamoeba castellanii* phagosomes.
