Antimicrobial susceptibility testing was performed using the E-test method according to CLSI M45 guidelines. Next-generation sequencing was performed for 14 clinical isolates, followed by hybrid assembly, resistance and virulence gene annotation using the CARD and VFDB databases, and single nucleotide polymorphism (SNP) phylogenetic analysis. Plasmid analysis was performed on four bloodstream isolates using Oxford Nanopore sequencing. A total of 312 clinical isolates were identified. All isolates were resistant to penicillin, meropenem, ceftriaxone, and ciprofloxacin but remained susceptible to vancomycin and linezolid. High resistance rates were also observed for tetracycline (69.87%), clindamycin (78.85%), gentamicin (44.23%), and erythromycin (79.17%). Genomic analysis identified 11 antimicrobial resistance genes, including the\n                      <jats:italic toggle=\"yes\">erm(X<\/jats:italic>\n                      ) gene, which was detected in all clinical isolates. In addition, resistance plasmids were identified, suggesting a potential role in the dissemination of antibiotic resistance. Multidrug-resistant\n                      <jats:italic toggle=\"yes\">C. striatum<\/jats:italic>\n                      is prevalent in this hospital setting. Continuous surveillance is warranted, and vancomycin and linezolid remain reliable therapeutic options.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>\n                        This study addresses a critical gap in the understanding of the emerging hospital pathogen\n                        <jats:italic toggle=\"yes\">Corynebacterium striatum<\/jats:italic>\n                        in China. The findings demonstrate that multidrug-resistant strains are already widespread in the clinical setting, with nearly all isolates showing resistance to multiple first-line antibiotics. The identification of resistance genes on mobile plasmids is particularly significant, as it suggests the potential for rapid dissemination to other bacteria. These findings are important for increasing awareness among clinicians and hospitals regarding this underrecognized threat. They also underscore the need for routine testing for accurate identification of this bacterium, support the preferential use of vancomycin or linezolid for treatment, and provide evidence for strengthening infection control measures to prevent outbreaks.\n                      <\/jats:p>\n                    <\/jats:sec>\n
