Methionine sulfoxide reductase B from Corynebacterium diphtheriae catalyzes sulfoxide reduction via an intramolecular disulfide cascade

Journal of Biological Chemistry, 2020
Corynebacterium diphtheriae is a human pathogen that causes diphtheria. In response to immune system-induced oxidative stress, C. diphtheriae expresses antioxidant enzymes, among which are methionine sulfoxide reductase (Msr) enzymes, which are critical ...

Genome‐Wide Analysis of DtxR and HrrA Regulons Reveals Novel Targets and a High Level of Interconnectivity Between Iron and Heme Regulatory Networks in Corynebacterium glutamicum

Molecular Microbiology, Volume 124, Issue 2, Page 115-130, August 2025.
Iron is essential for life, yet excessive levels can quickly lead to cellular damage via oxidative stress, underscoring the need for global regulators of iron and heme homeostasis. In this study, we present a genome‐wide analysis of the binding patterns of DtxR and HrrA in Corynebacterium glutamicum . Our findings highlight the interconnected nature of

Diphtheria: A case series from West Maharashtra, India

Journal of Medical Sciences and Health, 2022
Diphtheria is an acute infectious toxin mediated disease caused by Corynebacterium diphtheriae. Effective vaccination has decreased the incidence of disease globally. However, despite of a full-fledged Universal Immunization Programme, the cases

Corynebacterium diphtheriae Virulence Analyses Using a Caenorhabditis elegans Model

Current Protocols in Microbiology, 2020
Corynebacterium diphtheriae is the leading cause of pharyngeal diphtheria, a respiratory disease characterized by formation of a pseudomembrane at the site of infection. Although outbreaks of C.

Diphtheria diagnostic capacity in the Western Pacific Region

Western Pacific Surveillance and Response, 2019
Diphtheria is an acute infectious disease affecting the upper respiratory tract and occasionally the skin and is caused by the action of diphtheria toxin produced by Corynebacterium diphtheriae, Corynebacterium ulcerans and Corynebacterium ...

Cell Structure of Corynebacterium diphtheriae [PDF]

Journal of General Microbiology, 1951
SUMMARY: When examined by phase-contrast microscopy living diphtheria bacilli generally appear fairly transparent. They are sometimes unicellular but are frequently divided into compartments by readily visible cross-septa. In gravis and mitis strains the cross septa are usually few in number and the compartments long, but in intermedius strains there ...

Elucidating the Mechanism of Temporal Adaptation to Hydrogen Peroxide‐Induced Oxidative Stress in Corynebacterium glutamicum

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
In this study, RNA‐seq was employed to investigate the temporal transcriptional response of C. glutamicum ATCC 13032 to external H2O2 at 720 mM (2.45% w/w). The results reveal significant changes in gene expression across multiple pathways, including peroxide scavenging, central metabolism, sulphur and iron metabolism, amino acid biosynthesis, and DNA ...

Exudative Pharyngitis Possibly Due to Corynebacterium pseudodiphtheriticum, a New Challenge in The Differential Diagnosis of Diphtheria

Emerging Infectious Diseases, 1997
Corynebacterium pseudodiphtheriticum has rarely been reported to cause disease in humans, despite its common presence in the flora of the upper respiratory tract.

Eagle Effect inCorynebacterium diphtheriae [PDF]

The Journal of Infectious Diseases, 2005
The in vivo relevance of the paradoxical bactericidal effect (the Eagle effect) is not evident. We found in vitro a paradoxical bactericidal effect of amoxicillin on 2 strains of nontoxigenic Corynebacterium diphtheriae. Then, using an experimental rabbit model of endocarditis, we evaluated the in vivo relevance of this phenomenon.
