Production of diphtheria toxin by selected isolates of Corynebacterium ulcerans and Corynebacterium pseudotuberculosis [PDF]

Infection and Immunity, 1984
We determined the diphtheria toxin phenotype of specially selected isolates of Corynebacterium ulcerans and Corynebacterium pseudotuberculosis (C. ovis). All produced proteins similar in size and immunological structure to diphtheria toxin. As with diphtheria toxin, they exhibited ADP-ribosylating activity, and their synthesis was regulated by iron.

The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

FEBS Letters, Volume 599, Issue 9, Page 1203-1221, May 2025.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Understanding causes of morbidity and mortality in Southern Hemisphere small Odontoceti: a scoping review

Mammal Review, Volume 55, Issue 2, April 2025.
This review identifies key causes of morbidity and mortality in Southern Hemisphere small Odontoceti, highlighting significant anthropogenic threats and the enhanced need for conservation strategies. Key findings include high rates of entanglements and a diverse range of infectious pathogens. Abstract Marine mammals serve as sentinels for environmental

Role of microbiota in pain: From bench to bedside

iMetaOmics, Volume 2, Issue 1, March 2025.
Pain is closely linked to microbes. The microbiota modulates pain perception through three mechanisms: microbiota‐derived metabolites, immunoregulation, and direct stimulation on neurons. Therapeutic strategies like probiotics, fecal microbiota transplantation, and dietary changes show significant potential in pain management.

Outbreak with clonally related isolates of Corynebacterium ulcerans in a group of water rats [PDF]

, 2015
BACKGROUND: The zoonotic bacterium Corynebacterium ulcerans may be pathogenic both in humans and animals: toxigenic strains can cause diphtheria or diphtheria-like disease in humans via diphtheria toxin, while strains producing the dermonecrotic exotoxin

Possible human-to-human transmission of toxigenic Corynebacterium ulcerans [PDF]

, 2015
Toxigenic Corynebacterium ulcerans is an emerging cause of diphtheria. In contrast to the classical diphtheria pathogen C. diphtheriae, human-to-human transmission of this primarily zoonotic pathogen has not been clearly documented.

Pet and Stray Dogs’ Contribution to Zoonotic Transmission Pathways: A Bibliometric Review

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Based on a large‐scale bibliometric dataset, domestic dogs (Canis lupus familiaris) emerge as the most frequently cited host species in the context of zoonoses, being mentioned in at least 10% of publications for nearly a quarter of the pathogens recognized as zoonotic to humans.
