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.

Hidden diversity and expanded host range of sarthroviruses, including terrestrial vertebrates

This study expands the known diversity and host range of the Sarthroviridae family by discovering ten novel, highly divergent sarthrovirus species in diverse Australian hosts and environments, revealing a broader ecological distribution, multiple distinct lineages, and potential alternative replication strategies.

Implementing considered elements of standardisation for Time Kill Curve experiments across multiple sites: A European collaboration perspective

This European collaboration study identifies and evaluates critical technical variables—including inoculum preparation, culture agitation, and vessel size—to establish standardized protocols that improve the reproducibility and consistency of Time Kill Curve experiments across multiple laboratories.

Companion animals harbour globally circulating human-associated Klebsiella pneumoniae lineages and high-risk antimicrobial resistance clones

This study reveals that domestic dogs and cats harbor globally circulating, high-risk *Klebsiella pneumoniae* lineages and antimicrobial resistance clones that extensively overlap with human-associated populations, highlighting their significant role as reservoirs within the broader One Health AMR landscape.

Structure of the proton-powered secretion motor at the heart of the bacterial flagellum

This study presents high-resolution cryo-EM structures of the intact bacterial flagellar export apparatus, revealing a nonameric FlhA complex with a buried proton pathway and a symmetry-breaking conformation that suggests a rotary gating mechanism driven by proton motive force to regulate protein secretion.

Antibodies to influenza A virus hemagglutinin and neuraminidase limit egress and alter the physical properties of released virus particles

This study reveals that influenza A virus-specific antibodies not only neutralize mature virions but also actively interfere with viral egress by inducing particle aggregation and the release of elongated virions, thereby altering the physical properties and infectivity of the virus population during active infection.

Social network cycle motifs and gut microbiome strain-sharing

By analyzing strain-level microbial and friendship networks across 18 Honduran villages, this study reveals that while microbial transmission frequently occurs within cyclic social groups, the overlap between social and microbial cycles varies significantly by species, indicating that many microbes rely on transmission pathways only partially aligned with human social ties.

Laboratory adaptation and complete genome assembly of a Beposo, Ghana strain of the human hookworm Necator americanus

This study reports the successful laboratory adaptation of a human hookworm (*Necator americanus*) strain from Beposo, Ghana, to Golden Syrian hamsters and presents the first comprehensive characterization of this African strain, including its genetic diversity, drug susceptibility, and a high-quality complete genome assembly.

: A standardized bath challenge of Atlantic salmon reveals distinct infection dynamics and mortality across ten HPR-deleted infectious salmon anaemia virus isolates.

A standardized bath challenge of Atlantic salmon with ten ISAV-HPRΔ isolates revealed that while all strains caused systemic infection, they exhibited distinct virulence profiles ranging from low to high mortality driven by differences in infection dynamics and pathology that were not fully explained by genetic mutations or correlated with viral shedding levels.

Covalent Inhibition of New Delhi Metallo-β-Lactamases NDM-1 and NDM-5 by 3-Bromopyruvate

This study demonstrates that 3-bromopyruvate selectively restores meropenem efficacy against carbapenem-resistant bacteria expressing New Delhi metallo-β-lactamases (NDM-1 and NDM-5) by covalently modifying an active site cysteine residue, offering a promising new strategy for developing inhibitors against these metal-dependent enzymes.
