Corynebacterium diphtheriae infection as a dermatological problem – case report and review of the literature

Przegląd Dermatologiczny, 2019
We report the case of a 36-year-old male patient with alcohol dependence syndrome who was admitted to the Dermatology Unit with erythroderma of unknown aetiology persisting for approximately 2 years. A considerable degree of deformity and ulceration were

Spatiotemporal persistence of multiple, diverse clades and toxins of Corynebacterium diphtheriae

Nature Communications, 2021
Cases of diphtheria have increased in recent years. Here, the authors analyse the genomes of 502 Corynebacterium diphtheriae isolates across 16 countries and territories over 122 years, describing an increase in antimicrobial resistance genes and ...

PD‐L1‐Binding Antigen Presenters: Redirecting Vaccine‐Induced Antibodies for Cancer Immunotherapy

Advanced Science, Volume 13, Issue 20, 9 April 2026.
The PBAP‐gE complex anchors gE antigen to PD‐L1 on tumor cells. Vaccine‐induced anti‐gE antibodies simultaneously engage FcγRIIIa on NK cells and tumor‐bound PBAP‐gE, triggering NK cell activation and antibody‐dependent cellular cytotoxicity, thereby selectively eliminating PD‐L1–expressing tumor cells.

Optimizing Pediatric Tracheostomy Care: A Survey of Peri‐Operative Practices and Standardization in ASPO Members

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 2, April 2026.
ABSTRACT Objectives This ASPO survey investigates pediatric peri‐operative tracheostomy care practices through a nationwide survey. It aims to identify challenges, explore opportunities for standardization across institutions, and recommend strategies that could reduce complications and enhance patient care.

NGS-based phylogeny of diphtheria-related pathogenicity factors in different Corynebacterium spp. implies species-specific virulence transmission

BMC Microbiology, 2019
Background Diphtheria toxin (DT) is produced by toxigenic strains of the human pathogen Corynebacterium diphtheriae as well as zoonotic C. ulcerans and C. pseudotuberculosis.

Beyond diphtheria toxin: cytotoxic proteins of Corynebacterium ulcerans and Corynebacterium diphtheriae

Microbiology, 2019
Diphtheria toxin is one of the best investigated bacterial toxins and the major virulence factor of toxigenic Corynebacterium diphtheriae and Corynebacterium ulcerans strains. However, also diphtheria toxin-free strains of these two species can cause severe infections in animals and humans, indicating the presence of additional virulence factors.

Murine Intestinal Neonatal and Adult Dendritic Cell Subset Migration and Activation Characteristics in Response to Toll‐Like Receptor Stimulation Through MyD88

Scandinavian Journal of Immunology, Volume 103, Issue 4, April 2026.
Despite their importance, dendritic cell subsets are not well characterised in neonates. We here provide fundamental information on the abundance and phenotype of small‐intestinal neonatal DCs and assess the role of MyD88 in neonatal and adult DC migration in response to several toll‐like receptor ligands.

Nontoxigenic Corynebacterium diphtheriae: An Emerging Pathogen in England and Wales?

Emerging Infectious Diseases, 2000
Confirmed isolates of nontoxigenic Corynebacterium diphtheriae in England and Wales increased substantially from 1986 to 1994. Ribotyping of 121 isolates confirmed in 1995 showed that 90 were of a single strain isolated exclusively from the throat; none ...
