摘要：

Corynebacterium striatum (C. striatum) is a rapidly emerging multidrug-resistant organism commonly found as a skin and respiratory tract commensal. The first case of C. striatum infection was published in 1980 in a patient with chronic lymphocytic leukemia who had a pleuropulmonary infection. The chemotherapeutic agents used in hematologic malignancies completely deplete neutrophils, making them susceptible to various pathogens such as C. striatum, which are rarely pathogenic. The spectrum of presentation due to C. striatum includes severe bloodstream infections, pneumonia, meningitis, and infective endocarditis. Some of the most common risk factors are prolonged neutropenia with various invasive devices and numerous prophylactic antibiotics. This article aims to present three cases of C. striatum infections in immunocompromised patients at H. Lee Moffitt Cancer Centre. In such rare cases, infection prevention and appropriate antibiotic coverage are the key to preventing such infections.
