Megasphaera Elesdenii Dysregulates Colon Epithelial Homeostasis, Aggravates Colitis‐Associated Tumorigenesis

Advanced Science, EarlyView.
A fecal microbial meta‐analysis reveals that Megasphaera is highly abundant in the Asian population with IBD and CRC. M. elsdenii reshapes colonic immunity by triggering DC cell‐mediated Th1 and Th17 inflammation. M. elsdenii and M. elsdenii‐enriched microbiota exacerbate colonic inflammation and tumorigenesis in AOM/DSS mice.

An autopsy case of ventilator-associated tracheobronchitis caused by Corynebacterium species complicated with diffuse alveolar damage

Respiratory Medicine Case Reports, 2020
Ventilator-associated tracheobronchitis (VAT) has been reported to occur in 11% of intubated patients. Corynebacterium spp. can cause lower respiratory infections; however, to our knowledge, there have been no reported cases of VAT caused by ...

A Genetically Encoded Biosensor for Characterizing Transport and Metabolism of Glutarate

Advanced Science, EarlyView.
Here, a genetically encoded glutarate biosensor, Glusor, is developed based on transcriptional regulator CsiR. Glusor can quantify glutarate concentrations with good accuracy and precision. Then, the role of KgtP and YnfM are identified and characterized by using Glusor. Glusor also allows glutarate spatiotemporal resolution in live cells, facilitating

Engineering Dimensional Configuration of Single‐Atom S‐Cu‐S Sites as Reversible Electron Station for Enhanced Peroxidase‐Mimicking

Advanced Science, EarlyView.
L‐cysteine triggers auto‐assembly of POD‐like 3D biomimetic S‐Cu‐S single‐atom nanozymes on MoS2 (MoCC). MoCC shows 16.3‐fold higher catalytic velocity and 17.9‐fold greater affinity than HRP, enabling efficient •OH generation via enhanced electron inversion and transfer.

Fulminant infective endocarditis with toxin-negative Corynebacterium diphtheriae in people with substance use experiencing homelessness, England, 2024 to 2025

Eurosurveillance
Between July 2024 and January 2025, five male patients in their early 20s to early 50s were confirmed with infective endocarditis associated with non-toxigenic Corynebacterium diphtheriae in England. Three were known to have experienced homelessness. All

Novel Role of Gut‐Derived Roseburia Intestinalis in Safeguarding Intestinal Barrier Integrity and Microenvironment Homeostasis During Arsenic Exposure

Advanced Science, EarlyView.
Arsenic exposure disrupts intestinal barriers and gut microenvironment. Fecal microbiota transplantation (FMT) alleviates arsenic‐induced damage, with gut‐derived Roseburia intestinalis (R.i) identified as a key protective strain. R.i administration counters arsenic toxicity through immunomodulatory pathways and metabolites.

Skin-associated Corynebacterium amycolatum shares cobamides

mSphere
The underlying interactions that occur to maintain skin microbiome composition, function, and overall skin health are largely unknown. Often, these types of interactions are mediated by microbial metabolites.

Comparing Prophylactic Administration of Sulbactam/Ampicillin Versus Cefmetazole for Prevention of Perineal Wound Infection Following Abdominoperineal Resection for Rectal Cancer: A Multicenter Randomized Controlled Trial

Annals of Gastroenterological Surgery, EarlyView.
This prospective randomized trial demonstrated that a 4‐day regimen of sulbactam/ampicillin significantly reduced the incidence of perineal wound infection (PWI) following abdominoperineal resection compared to a 1‐day cefmetazole regimen. This simple approach to antibiotic selection may be beneficial for preventing PWI.

Identification and Characterization of Corynaridin, a Novel Linaridin from Corynebacterium lactis

Microbiology Spectrum, 2023
Genome analysis of Corynebacterium lactis revealed a bacteriocin gene cluster encoding a putative bacteriocin of the linaridin family of ribosomally synthesized and posttranslationally modified peptides (RiPPs).

Corynebacterium ulcerans and Corynebacterium pseudotuberculosis responses to DNA probes derived from corynephage beta and Corynebacterium diphtheriae [PDF]

Infection and Immunity, 1984
Strains of Corynebacterium ulcerans and Corynebacterium pseudotuberculosis (Corynebacterium ovis) were examined for the production of diphtheria toxin. A majority of C. ulcerans strains (25 of 37) and 1 C. pseudotuberculosis strain (1 of 14) gave a positive Elek test for diphtheria toxin, and for all strains but 1, production of diphtheria toxin was ...
