A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

Advanced Science, EarlyView.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

Advanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

South African Propolis: Anti‐Helicobacter pylori Activity, Chemistry, and Toxicity

Chemistry &Biodiversity, EarlyView.
ABSTRACT Propolis, a resin‐like substance produced by bees, has previously shown antimicrobial activity against the ulcer‐causing gut pathogen Helicobacter pylori. South African propolis, however, was yet to be investigated. This study aimed to investigate a comprehensive range of South African propolis for its antimicrobial activity against H.

A novel mouse model of Campylobacter jejuni enteropathy and diarrhea

bioRxiv, 2018
Campylobacter infections are among the leading bacterial causes of diarrhea and of ‘environmental enteropathy’ (EE) and growth failure worldwide. However, the lack of an inexpensive small animal model of enteric disease with Campylobacter has been a ...

Sputum Microbiota Compositions Correlate With Metabolome and Clinical Outcomes of COPD‐Bronchiectasis Association: A Prospective Cohort Study

Exploration, EarlyView.
This study aimed to determine how microbiota compositions (via 16S rRNA sequencing) correlate with clinical outcome and metabolome (via liquid chromatography/mass spectrometry) of CBA. Sputum microbiome and metabolome profiles of CBA were well separated from COPD but not bronchiectasis, partly driven by the higher abundance of Proteobacteria in CBA ...

Epidemiology and Impact of Campylobacter Infection in Children in 8 Low-Resource Settings: Results From the MAL-ED Study

Clinical Infectious Diseases, 2016
In a multisite birth cohort study, we document a high burden of Campylobacter infection using enzyme immunoassay, demonstrate an association between Campylobacter and linear growth shortfalls and both increased intestinal permeability and intestinal and ...

Gut Microbiota‐Associated Metabolites Affected the Susceptibility to Heart Health Abnormality in Young Migrants at High‐Altitude

Exploration, EarlyView.
Long‐term migration to high‐altitude areas can readily result in chronic high‐altitude diseases; however, effective prevention and treatment methods are currently lacking. This study employed a multi‐omics approach, integrating metagenomics and metabolomics, to discover and validate that the decreased abundance of Veillonella rogosae, Streptococcus ...
