Phage‐mediated horizontal transfer of Salmonella enterica virulence genes with regulatory feedback from the host

iMeta, Volume 4, Issue 4, August 2025.
In this study, we found evidence of phage‐mediated horizontal transfer of virulence genes in Salmonella enterica in global habitats from a molecular evolutionary perspective. Notably, csrA, a global regulator in Salmonella enterica, curbed horizontal gene transfer by inhibiting the cyclization and release of prophage.

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 ...

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

Multiplex PCR assay for identification of Corynebacterium pseudotuberculosis from pure cultures and for rapid detection of this pathogen in clinical samples. [PDF]

, 2019
: Corynebacterium pseudotuberculosis is the aetiological agent of caseous lymphadenitis (CLA), a debilitating disease of sheep and goats. Accurate diagnosis of CLA primarily relies on microbiological examination, followed by biochemical identification of

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 ...
