Overexpression of Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model

Microbiology and Immunology, EarlyView.
ABSTRACT The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high‐throughput screening, together with an Escherichia ...

Ecophysiological Features Shape the Distribution of Prophages and CRISPR in Sulfate Reducing Prokaryotes

Microorganisms, 2021
Sulfate reducing prokaryotes (SRP) are a phylogenetically and physiologically diverse group of microorganisms that use sulfate as an electron acceptor. SRP have long been recognized as key players of the carbon and sulfur cycles, and more recently, they ...

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Isolation of Extracellular Vesicles From Gram‐Negative Bacteria: A Solid Medium‐Based Method Analysis

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
ABSTRACT Extracellular vesicles (EVs) produced by gram‐negative bacteria have gained increased scientific interest over the last years due to a growing understanding of their roles in pathogenesis and biotechnological potential. However, isolating such nanoparticles is technically challenging. Here, we evaluated a rapid and reproducible protocol for EV

Whole‐Genome Sequence Profiling of Listeria innocua From Different Sources: Implications for Public Health

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
The studied strains, LIN_NWU_CNKT and LIN5_NWU_CNKT, exhibit invasiveness, pathogenicity, and MDR profiles. The isolation of these strains from food products and water underscores their significant public health implications, particularly in the context of the “One Health” concept.

Highly accurate prophage island detection with PIDE

Genome Biology
As important mobile elements in prokaryotes, prophages shape the genomic context of their hosts and regulate the structure of bacterial populations. However, it is challenging to precisely identify prophages through computational methods.

Differential Analysis of IAA Anabolism Pathway Based on Bacillus cereus, Bacillus subtilis and Bacillus safensis Genome

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Three Bacillus species isolated from Platycladus orientalis rhizosphere in Taihang Mountains: Bacillus cereus has 3 IAA synthesis pathways (TAM, IAM, IPyA); Bacillus subtilis has IAM/IPyA; and Bacillus safensis only has IPyA (via whole‐genome sequencing).

The genome and stage‐specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions

Insect Molecular Biology, Volume 35, Issue 2, Page 126-138, April 2026.
Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

Defense Systems and Prophage Detection in Streptococcus mutans Strains

Molecular Oral Microbiology, Volume 41, Issue 2, Page 57-68, April 2026.
ABSTRACT Although the species is extensively studied, limited data are available on antiphage defense systems (APDSs) in Streptococcus mutans. The present study aimed to explore the diversity and the occurrence of APDSs and to search for prophages in the genomes of clinical isolates of S. mutans using bioinformatics tools.
