The Type VI secretion systems of the insect pathogen Photorhabdus luminescens are involved in interbacterial competition, motility and secondary metabolism

The Microbe
The Type VI Secretion System (T6SS) is used as weapon by a variety of Gram-negative bacteria in polymicrobial niche competition. Its characterization and study gained more interest in recent years.

Syndromic Convergence in Aquaculture Disease Management: A Critical Review of Climate‐Pathobiome Interactions, Diagnostic Frameworks, and Knowledge Gaps

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Syndromic convergence (SyCo) reframes aquaculture disease as the synergistic product of climate‐driven stressors, pathobiome communities, and host immune compromise, not single pathogens. A five‐criterion scoring matrix, composite early warning index, and three‐layer intervention framework together operationalize this shift toward predictive ...

Calcium Promotes T6SS-Mediated Killing and Aggregation between Competing Symbionts

Microbiology Spectrum, 2022
Microbes deploy competitive mechanisms to gain access to resources such as nutrients or space within an ecological niche. Identifying when and where these strategies are employed can be challenging given the complexity and variability of most natural systems; therefore, studies evaluating specific cues that conditionally regulate interbacterial ...

The Tip of the VgrG Spike Is Essential to Functional Type VI Secretion System Assembly in Acinetobacter baumannii

mBio, 2020
The type VI secretion system (T6SS) is a critical weapon in bacterial warfare between Gram-negative bacteria. Although invaluable for niche establishment, this machine represents an energetic burden to its host bacterium.

The Role of the Gut Microbiota in Allogeneic Hematopoietic Cell Transplantation

American Journal of Hematology, Volume 101, Issue 8, Page 1980-1996, August 2026.
ABSTRACT Allogeneic hematopoietic cell transplantation (allo‐HCT) is an effective treatment for patients with high‐risk hematologic malignancies. Over the last decade, gut microbiota composition during allo‐HCT has been associated with patients' outcomes.

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, Volume 5, Issue 4, August 2026.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Thirteen‐year genomic analysis (2010–2022) reveals high‐risk ICU Pseudomonas aeruginosa in China

mLife, Volume 5, Issue 4, Page 459-472, August 2026.
Abstract Pseudomonas aeruginosa is a significant opportunistic pathogen, particularly prevalent in intensive care units (ICUs). Through a comprehensive genomic and phenotypic analysis of 518 ICU and healthy isolates collected over a 13‐year period (2010–2022), we found that ICU strains, despite reduced sequence type (ST) diversity, are dominated by ...
