AI Article Synopsis

  • * The study provides nearly complete chemical shift assignments for a 215-amino acid heme oxygenase (HO) from Corynebacterium diphtheria in different forms.
  • * These assignments will help determine which parts of the heme oxygenase change when binding to compounds, aiding the development of specific inhibitors for these bacterial proteins.

Article Abstract

We are employing a number of selective in vitro and in vivo methods including NMR to screen compounds that bind to heme oxygenases from pathogenic bacteria. We report the nearly complete HN, N, CO, Calpha and Cbeta chemical shift assignments of a 215-amino acid HO from Corynebacterium diphtheria in three forms, apo cd-HO-G135A, apo cd-HO and CO-bound ferrous holo cd-HO; these assignments will enable us to identify residues on cd-HO that are perturbed upon binding to selected compounds, and to help with the development of inhibitors specific to the bacterial proteins.

We report a cluster of infections with genetically related toxigenic Corynebacterium diphtheriae linked to an outbreak among asylum seekers in Switzerland that subsequently affected patients without known exposure. This discovery highlights the importance of rapid, interdisciplinary outbreak investigations and regular vaccination status assessment, especially in elderly populations with waning immunity.

usually presents with erythrasma, a macular rash, but rarely it can cause extracutaneous infections such as endocarditis, peritonitis, pyelonephritis, and catheter-related bloodstream infections. Here, we present the first case of septic arthritis caused by and a literature review of invasive infections. The diagnosis was confirmed by the patient's clinical findings and microbiological examination of the joint fluid.

The objective of this study was to investigate the chemical composition of Syzygium aromaticum essential oil (SAEO), both as its toxicity and biological activities on Corynebacterium diphtheriae. The essential oil (EO) was obtained by hydrodistillation and verified by GC-MS. The main chemical components were eugenol (48.

In the European region, diphtheria is now rarely suspected in patients presenting with upper respiratory tract symptoms. is the underestimated zoonosis that is replacing infections in industrialized countries, but extensive human and animal prevalence studies are lacking. The range of hosts that can act as reservoirs for is very broad, companion pets currently being the main source of human infection.

Toxin-producing strains are the etiological agents of the severe upper respiratory disease, diphtheria. A global phylogenetic analysis revealed that biotype gravis is particularly lethal as it produces diphtheria toxin and a range of other virulence factors, particularly when it encounters low levels of iron at sites of infection. To gain insight into how it colonizes its host, we have identified iron-dependent changes in the exoproteome and surfaceome of strain 1737 using a combination of whole-cell fractionation, intact cell surface proteolysis, and quantitative proteomics.
