When isolated from clinical specimens, nondiphtherial Corynebacteria, such as Corynebacterium striatum, Corynebacterium amycolatum. ABSTRACT. We describe an unusual cluster of Corynebacterium striatum infections in 21 patients with chronic obstructive pulmonary disease (COPD) admitted. Objective: To evaluate the clinical significance of and describe factors associated with Corynebacterium striatum infection. Methods: A.

We consider patterns E and A as high-prevalence pulsotypes. This would eventually lead this strain to become a secondary corynebscterium in immunocompromised hosts [ 8 ]. Amikacin is eventually prescribed in combinative therapy against severe infections caused by C.

Performance Standards for Antimicrobial Susceptibility Testing. Susceptibility of 63 Corynebacterium striatum clinical isolates to 16 antimicrobial agents. In all cases the Corynebacterium were isolated after two different culture sets. However, this gene was also detected in strains susceptible to kanamycin, probably due to mutations affecting its coding sequence or its promoter.

They are pleomorphic through their stdiatumthey occur in various lengths, and they frequently have thickenings at either end, depending on the surrounding conditions. Sstriatum is an acute and contagious infection characterized by pseudomembranes of dead epithelial cellswhite blood cellsred blood cellsand fibrin that form around the tonsils and back of the throat.

MLS resistance in Corynebacterium spp. Some PFGE patterns were more frequently isolated, suggesting the existence of a few more prevalent clones.


Additionally, 16 conserved signature proteins, which are uniquely found in Corynebacterium species, have been identified. Letters in Applied Microbiology.

At this time, another two sets of blood samples were collected and blood cultures were negative. Clostridiales Halanaerobiales Thermoanaerobacteriales Natranaerobiales Negativicutes Selenomonadales. Pulsed field gel electrophoresis: Indian Journal of Medical Microbiology.

Corynebacterium striatum: a diphtheroid with pathogenic potential.

Therefore, two sets of blood samples for blood culture were collected. Some asynergy in wall motion was detected by echocardiography, but no vegetation was seen.

Three of the conserved signature proteins have homologs found in the genus Dietziawhich is believed to be the closest related genus to Corynebacterium. Actinomycetaceae Actinomyces israelii Actinomycosis Cutaneous actinomycosis Tropheryma whipplei Corynebacterikm disease Arcanobacterium haemolyticum Arcanobacterium haemolyticum infection Actinomyces corynebactrrium. Complete genome sequence, lifestyle, and multi-drug resistance of the human pathogen Corynebacterium resistens DSM isolated from blood samples of a leukemia patient.

The bacteria group together in a characteristic way, which has been described as the form of a “V”, “palisades”, or “Chinese letters”.

Corynebacterium striatum: a diphtheroid with pathogenic potential.

All strains were susceptible to vancomycin, linezolid, and daptomycin. Patients with a history of exposure to broad-spectrum antibiotics or immunosuppression, as well as critically ill patients with an implanted indwelling device or a central venous catheter, must be considered at high risk of severe infection for this type of bacteria and it is necessary to recognize C.


In the present case, we report a catheter-related bloodstream infection caused by C.

Unwanted side reactions such as threonine and asparagine production can occur if a buildup of intermediates occurs, so scientists have developed mutant strains of C.
