Molecular characterization and phylogenetic analysis of the first Corynebacterium rouxii strains isolated in Brazil: a recent member of Corynebacterium diphtheriae complex [PDF]

BMC Genomic Data, 2023
Background Corynebacterium diphtheriae complex was formed by the species C. diphtheriae, Corynebacterium ulcerans and Corynebacterium pseudotuberculosis in the recent past. In addition to C. diphtheriae, C. ulcerans and C.

Distinct Genomic Features Characterize Two Clades of Corynebacterium diphtheriae: Proposal of Corynebacterium diphtheriae Subsp. diphtheriae Subsp. nov. and Corynebacterium diphtheriae Subsp. lausannense Subsp. nov.

Frontiers in Microbiology, 2018
Corynebacterium diphtheriae is the etiological agent of diphtheria, a disease caused by the presence of the diphtheria toxin. However, an increasing number of records report non-toxigenic C. diphtheriae infections. Here, a C.

Non-toxigenic Corynebacterium diphtheriae in hallux ulceration

Journal of Infection in Developing Countries, 2022
Introduction: Toxigenic Corynebacterium diphtheriae causes classical diphtheria. Skin infections by toxigenic or non-toxigenic Corynebacterium diphtheriae are prevalent in the tropics but are rarely reported.

A global Corynebacterium diphtheriae genomic framework sheds light on current diphtheria reemergence

bioRxiv, 2023
Background Diphtheria, caused by Corynebacterium diphtheriae, reemerges in Europe since 2022. Genomic sequencing can inform on transmission routes and genotypes of concern, but currently, no standard approach exists to detect clinically important genomic

Screening for Corynebacterium diphtheriae. [PDF]

Journal of Clinical Pathology, 1992
A throat swab from a 9 year old girl with pharyngitis yielded a non-toxigenic strain of Corynebacterium diphtheriae var mitis and Streptococcus group G. C pseudodiphtheriticum was isolated from the throats of two of her four brothers. In each case the isolate was sent to the reference laboratory before full identification.

Re-emergence of Corynebacterium diphtheriae [PDF]

Médecine et Maladies Infectieuses, 2019
Diphtheria is re-emerging in Europe. A total of 36 cases were reported in Europe in 2015 versus 53 cases between 2000 and 2009.We report two cases of Corynebacterium diphtheriae infection in a French hospital in 2016: a cutaneous infection with negative toxin testing in a French traveller, and a respiratory diphtheria carriage with positive toxin ...
