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.

Linezolid has also shown an excellent activity, with MICs routinely below 0. Several species cause disease in animals, most notably C. This would eventually lead this strain to become a secondary colonizer in immunocompromised hosts [ 8 ]. All authors reviewed and approved the manuscript. The most notable human infection is diphtheriacaused by C.

Corynebacterium striatum: a diphtheroid with pathogenic potential.

Unfortunately, we could not successfully treat the patient because of her poor general condition corynnebacterium comorbidity. The Corynebacteria are divided into two groups: The fact that many different antibiotic resistance profiles could be distinguished among the strains belonging to a particular PFGE pattern revealed that there was not a single strain but several closely related clones producing sporadic infections.

To view a copy of this license, visit http: In TSA, they can form grey colonies with black centers and dentated borders that look similar to flowers C. Among the several clones of C. Most species of corynebacteria are not lipophilic.

Discussion One of the most serious problems related to treatment of the infections caused by C. The ampC gene was detected in 22 of the 28 cefotaxime-resistant C. Linezolid can be considered as an alternative to vancomycin against C. Forty-six out of the 63 C.

Therefore, two sets of blood samples for blood culture were collected. However, most of these cases are represented by patients with implanted indwelling devices or who present an immunosuppression [ 26 ]. Because her general condition worsened, corynebaxterium indwelling ztriatum as central venous catheter might cause bacteremia by C.

The IABP was removed on day 16 of admission. Aminoglycoside resistance occurs through several mechanisms that can coexist simultaneously in the same cell.

Both of these indels serve as molecular markers for species of the genus Corynebacterium. In the present case, we report a catheter-related bloodstream infection caused by C. Antimicrobial susceptibilities of Corynebacterium species and other non-spore-forming gram-positive bacilli corynrbacterium 18 antimicrobial agents.

Tobramycin was also very active 56 isolates were susceptible. However, the occurrence of resistant strains requires continual vigilance.

Tauch A, et al. MLS resistance in Corynebacterium spp. The genus Corynebacterium was created by Lehmann and Neumann in as a taxonomic group to contain the bacterial rods responsible for causing diphtheria. The presence of aminoglycoside modifying enzyme AME genes common in Corynebacterium spp. International Journal of Cosmetic Science.

The most frequently encountered resistance phenotype was penicillin 12 strainsfollowed by penicillin-cefotaxime and erythromycin-clindamycin-penicillin 6 strains each. Corynebacterium striatum pneumonia in an HIV patient. Medically relevant Corynebacterium species include Corynebacterium diphtheriaethe primary cause of diphtheria, and the non-diphtherial corynebacteria, which are part of the normal flora of the skin and mucous membranes.


An emerging nosocomial pathogen in a case of laryngeal carcinoma. The bacteria grow in Loeffler’s mediumblood agarand trypticase soy agar TSA. Susceptibility to aminoglycosides and distribution of aph and aac 3 -XI genes among Corynebacterium striatum clinical isolates. Some strains also need thiamine and PABA. The bacteria group together in a characteristic way, which has been described as the form of a “V”, “palisades”, or “Chinese letters”. Report of a case with polymicrobial endocarditis related to multiresistant strains.

We obtained XbaI macro-restriction patterns of the 63 C. They may also appear elliptical. Patient-to-patient spread of a single strain of Corynebacterium striatum causing infections in a surgical intensive care unit. In other projects Wikimedia Commons Wikispecies.

Corynebacterium striatum: a diphtheroid with pathogenic potential.

Clonal multidrug-resistant Corynebacterium striatum strains, Italy. Outbreaks caused by multidrug-resistant C. Our results indicate that amikacin is the preferable aminoglycoside for treatment of C. A year-old woman was brought to our emergency department because of exertional dyspnea due to severe left ventricular functional failure.

Table of Contents Alerts. Some PFGE patterns were more frequently isolated, suggesting the existence of a few more prevalent clones.
