Bacterial extracellular vesicles (BEVs) enable communication between bacteria and their natural habitats, including multicellular organisms such as humans. Consequently, the study of BEVs has rapidly gained attention with recent research raising the prospect of developing BEVs as biomarkers and treatments to manage (mal)functioning of natural habitats. Although diverse technologies are available, the composition of their source, their heterogeneity in biophysical and biochemical features, and their multifaceted cargo composition challenges the analysis of BEVs. To map current practices in BEV research, we analyzed 845 publications released in 2015-2021, reporting 3338 BEV-related experiments. The extracted data are accessible via the publicly available EV-TRACK knowledgebase ( https://evtrack.org/ ). We identify the need for transparent reporting, delineate knowledge gaps, outline available best practices and define areas in need of guidance to ensure advances in BEV research and accelerate BEV applications.

Citrobacter freundii, a common zoonotic pathogen affecting humans, livestock and fish, is recognized for its substantial impact on largemouth bass (Micropterus salmoides) mortality. However, the mechanisms of C. freundii infection in largemouth bass remain poorly understood.

Rice bacterial leaf streak (BLS) caused by Xanthomonas oryzae pv. oryzicola (Xoc) significantly reduces rice yield and quality. Traditional chemical control methods often have limited efficacy and raise environmental concerns, highlighting the need for safer and more effective alternatives.

The rice foot rot disease caused by Dickeya oryzae is an important bacterial disease that could cause tremendous economic losses. The virulence factor modulating cluster (Vfm) quorum sensing (QS) system, a major virulence regulatory mechanism conserved in the Dickeya genus, controls the production of zeamines and various extracellular cell wall degradation enzymes in D. oryzae.

Infected wounds remain a major clinical challenge due to bacterial invasion, which disrupts the natural healing cascade through excessive reactive oxygen species (ROS) generation, severe vascular damage, and persistent inflammation. Inspired by the catechol-rich adhesive domains of mussel foot proteins, we developed an extracellular matrix (ECM)-mimetic polyethylene glycol (PEG) hydrogel incorporating polydopamine (PDA)-functionalized zinc oxide nanoparticles (ZnONPs) for infected wound therapy. The amino acid-functionalized PEG hydrogel reproduces ECM-like properties to facilitate cell migration and efficient exudate management; however, its lack of intrinsic antimicrobial activity limits therapeutic efficacy.

This study explores the role of α-Fe₂O₃ in improving extracellular electron transfer (EET) and symbiotic interactions between electroactive Shewanella oneidensis MR-1, its gene-deficient mutants (ΔmtrC, ΔomcA, and ΔcymA), and microalgae (Chlorella vulgaris). The iron oxide facilitates the efficient transfer of electrons generated by MR-1 to microalgal photosystem via the pathway of CymA-MtrC-OmcA to α-Fe₂O₃. This process enhances the removals of TOC, TN, and NH₄⁺-N in the MR-1 bacterial-algal consortium by 9.
