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

open access: yesBMC 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.

Rhodococcus aetherivorans BCP1 as cell factory for the production of intracellular tellurium nanorods under aerobic conditions [PDF]

open access: yes, 2016
Background: Tellurite (TeO32-) is recognized as a toxic oxyanion to living organisms. However, mainly anaerobic or facultative-anaerobic microorganisms are able to tolerate and convert TeO32- into the less toxic and available form of elemental Tellurium (

Microbiome and Metaproteome of Craniofacial Implant Regions in Health and Disease

open access: yesOral Diseases, Volume 31, Issue 11, Page 3190-3200, November 2025.
ABSTRACT Background Craniofacial defects from cancer surgery led to functional, aesthetic, and psychological challenges. Rehabilitation with craniofacial implants addresses these issues by improving prosthesis retention through osseointegration and providing predictable cosmetic results. However, maintaining a healthy transcutaneous region is essential

Perbandingan Pemeriksaan Toksigenisitas secara Genotip dan Fenotip pada Beberapa Isolat Corynebacterium Diphtheriae Penyebab Difteri di Indonesia [PDF]

open access: yes, 2016
Corynebacterium diphteriae's toxin can be detected by using in vivo and in vitro examination. Detection of the toxin using the Guinea pig is a gold standard. This method requires a long time and has been opposed by animal right organization.

Next-generation systematics: An innovative approach to resolve the structure of complex prokaryotic taxa [PDF]

open access: yes, 2016
Prokaryotic systematics provides the fundamental framework for microbiological research but remains a discipline that relies on a labour- and time-intensive polyphasic taxonomic approach, including DNA-DNA hybridization, variation in 16S rRNA gene ...

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

open access: yesMicrobiology, 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.

Polyanhydride‐Based Microparticles for Programmable Pulsatile Release of Diphtheria Toxoid (DT) for Single‐Injection Self‐Boosting Vaccines

open access: yesAdvanced Materials, Volume 37, Issue 32, August 14, 2025.
This study presents a polyanhydride‐based delivery platform for single‐injection, self‐boosting vaccines. The system enables programmable, pulsatile release of diphtheria toxoid with high antigen recovery and is guided by machine learning for tunability. In vivo results show immune responses comparable to multi‐dose regimens, highlighting its potential
