Biofilm Formation and Antimicrobial Susceptibility of Non-Diphtheria Corynebacterium Strains Isolated from Blood Cultures: First Report from Turkey

Totally Implantable Central Venous Access Port-Associated Bloodstream Infection Caused by Corynebacterium provencense: The First Case Report

Corynebacterium species are associated with healthcare-associated infections, specifically in device implantation. Here, we report a rare case of a 44-year-old man with a totally implantable central venous access port-related Corynebacterium infection. When he developed a fever on day four of admission, vancomycin treatment was initiated. On the 11th day, the totally implantable central venous access port was removed. Corynebacterium provencense was identified from two sets of blood cultures. Vancomycin treatment was continued for 14 days after port removal, and the patient was discharged home on the 47th day. Although C. provencense infection had not been previously reported in humans, it could be treated by port removal and vancomycin administration, as demonstrated in other reports on Corynebacterium infections.

Corynebacterium striatum Bacteremia during SARS-CoV2 Infection: Case Report, Literature Review, and Clinical Considerations

Bacterial infections, especially those in hospital settings, represent a major complication of COVID-19 patients, complicating management and worsening clinical outcomes. Corynebacterium striatum is a non-diphtheric actinobacterium that has been reported as being the causative agent of several different infections, affecting both immunocompetent and immunocompromised patients. Recently, C. striatum has been recognized as a nosocomial pathogen that is responsible for severe infection in critical patients, as well as in fragile and immunocompromised subjects. C. striatum has been described as the etiological agent of bacteremia, central line infections, and endocarditis. We report a case of a 91-year-old woman who was hospitalized due to SARS-CoV-2 infection, who developed C. striatum bacteremia and died despite antimicrobial therapy and clinical efforts. Furthermore, we discuss C. striatum diagnosis and treatment based on evidence from the scientific literature.
