Corynebacterium kroppenstedtii has been associated with infections of the female breast. Genome sequencing of two strains revealed a specific genomic island in the multidrug-resistant isolate CNM633/14 with similarity to the R plasmid pJA144188 of Corynebacterium resistens DSM 45100, being indicative of the horizontal transfer of antibiotic resistance genes to C. kroppenstedtii.

Corynebacterium species are well-known causes of catheter-related bloodstream infections. Toxigenic strains of Corynebacterium diphtheriae cause respiratory diphtheria. We report a bloodstream infection caused by a nontoxigenic strain of C. diphtheriae and discuss the epidemiology, possible sources of the infection, and the implications of rapid species identification of corynebacteria.

Since its original description in 1961, Corynebacterium minutissimum, the causative agent of erythrasma, has rarely been associated with extracutaneous disease. We report a case of cellulitis and bacteremia due to C. minutissimum. We discuss the treatment of C. minutissimum infection and describe the clinical settings in which isolation of Corynebacterium species from blood cultures should be c...

We report the main characteristics of 'Actinomyces provencensis' strain SN12T sp. nov., 'Corynebacterium bouchesdurhonense' strain SN14T sp. nov., 'Corynebacterium provencense' strain SN15T sp. nov. and 'Xanthomonas massiliensis' strain SN8T sp. nov., which were all isolated from stool samples from obese French patients.

In the context of the European migrant crisis, more and more cases of cutaneous diphtheria are seen. A typical presentation includes painful cutaneous ulcerations with grayish-whitish pseudomembranes. Here we present 2 male Eritrean patients suffering from cutaneous nontoxigenic Corynebacterium diphtheriae (patient 1) and Corynebacterium striatum (patient 2) infection.

Corynebacterium casei is one of the most prevalent species present on the surfaces of smear-ripened cheeses, where it contributes to the production of the desired organoleptic properties. Here, we report the draft genome sequence of Corynebacterium casei UCMA 3821 to provide insights into its physiology.

The complete genome sequence of Corynebacterium epidermidicanis DSM 45586 comprises 2,692,072 bp with 58.06% G+C content. The annotation revealed 2,466 protein-coding regions, including genes for surface-anchored proteins with Cna B-type or bacterial Ig-like domains and for an adhesive SpaABC-type pilus with similarity to fimbrial subunits of Corynebacterium resistens DSM 45100.

The in vitro activity of ketolide HMR 3647 against coryneform bacteria isolated from clinical samples was evaluated. Except against Corynebacterium jeikeium and C. urealyticum, HMR 3647 showed high activity against Corynebacterium spp., being more active than 14- and 16-membered macrolides, azithromycin, or clindamycin. HMR 3647 also had high in vitro activity against Brevibacterium spp. and Li...

Throat swabs from 113 healthy individuals from Hamburg, Germany, and Zurich, Switzerland, were investigated for coryneform bacteria with nonselective and selective media. Ninety specimens contained 123 strains. Surprisingly, 76% of them were strains of Corynebacterium durum (47%) and Rothia dentocariosa (29%). Only two were strains of Corynebacterium pseudodiphtheriticum, and none were strains ...
