Phenotypic, molecular characterization, antimicrobial susceptibility and draft genome sequence of Corynebacterium argentoratense strains isolated from clinical samples.

During a 12-year period we isolated five Corynebacterium argentoratense strains identified by phenotypic methods, including the use of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF) and 16S rRNA gene sequencing. In addition, antimicrobial susceptibility was determined, and genome sequencing for the detection of antibiotic resistance genes was performed. The organisms were isolated from blood and throat cultures and could be identified by all methods used.

First report of bacteremia by Janibacter terrae in humans.

The genus Janibacter comprises nine different species mainly found in the environment. Only two human infections by these microorganisms have been previously reported, one by J. melonis and another one by an undescribed Janibacter sp.

Isolation of Corynebacterium ureicelerivorans from normally sterile sites in humans.

Fifteen Corynebacterium ureicelerivorans isolates were recovered in pure culture from six patients during a five-year period. Five patients had bacteremia and the other was an infection of ascitic fluid. The API Coryne numerical profile obtained corresponds to the profile for C.

The isolation of Corynebacterium coyleae from clinical samples: clinical and microbiological data.

Fourteen Corynebacterium coyleae isolates were recovered from 12 in-patients during a 5-years period. In six patients, the isolates were considered as clinically significant, three definite (sepsis), two probable (sepsis and soft tissue infection), and one possible (post-transfusional bacteremia). In the remaining 6 patients (all neonatal bacteremias), there was not enough data for considering the isolates as clinical significant.
