Yersinia pestis Actively Inhibits the Production of Extracellular Vesicles by Human Neutrophils

open access: yesJournal of Extracellular Vesicles, Volume 14, Issue 4, April 2025.
Typically, neutrophils respond to invading pathogens by altering the cargo packaged into EVs and increasing EV release, which enhances antimicrobial responses. However, we show here that the bacterial pathogen Yersinia pestis injects Yop effector proteins into neutrophils to actively inhibit EV biogenesis, resulting in limited EV release and ...

Use of Water Quality Index and Pesticides‐Related Human Health Risk Assessment for Evaluating the Surface Water Sustainability Status of the Kakia‐Esamburmbur Agricultural Watershed, Narok County, Kenya

open access: yesGeoHealth, Volume 9, Issue 4, April 2025.
Abstract The increase in water contaminants threatens ecosystems and human health, underscoring the need for effective water quality (WQ) control. This study assessed the Kakia‐Esamburmbur catchment's water sustainability status for drinking purposes by analyzing water samples from the catchment.

Modeling the combined impact of water activity and temperature on Salmonella Montevideo thermal inactivation on dried chili peppers

open access: yesJournal of Food Science, Volume 90, Issue 4, April 2025.
Abstract Salmonella contamination in low‐moisture foods remains a continuing food safety and public health problem. The World Health Organization ranked unprocessed red chili peppers as the spice with the highest risk of Salmonella contamination in a risk assessment‐based report in 2022.

Enhancing AI microscopy for foodborne bacterial classification via adversarial domain adaptation across optical and biological variability [PDF]

open access: yesarXiv
Rapid detection of foodborne bacteria is critical for food safety and quality, yet traditional culture-based methods require extended incubation and specialized sample preparation. This study addresses these challenges by i) enhancing the generalizability of AI-enabled microscopy for bacterial classification using adversarial domain adaptation and ii ...

Genetic Dissection of Cyclic di‐GMP Signalling in Pseudomonas aeruginosa via Systematic Diguanylate Cyclase Disruption

open access: yesMicrobial Biotechnology, Volume 18, Issue 4, April 2025.
All 32 diguanylate cyclase (DGC)‐encoding genes of P. aeruginosa PA14 were interrupted by premature STOP codons, introduced through a multiplexed cytosine base‐editor. The synthesis of c‐di‐GMP was impaired in the resulting strain lacking all 32 DGCs (strain PA14Δ32). Phenotypic analysis confirmed major behaviour changes in P. aeruginosa PA14Δ32, which
