Abstract

Staphylococcus epidermidis is an important cause of bloodstream infections and a cause of morbidity and mortality in cancer patients. The antimicrobial resistance profiles of S. epidermidis septicemia in Vietnamese cancer patients are limited. We surveyed all S. epidermidis blood culture isolates from Vietnamese cancer patients at the Tan Trieu National Cancer Hospital, from 2020 to 2024. A total of 11 S. epidermidis isolates were identified and antibiotic susceptibility testing was employed. Methicillin resistance was detected in 4/11 of all isolates; all were sensitive to vancomycin, nitrofurantoin, linezolid, quinupristin-dalfopristin; however, all were resistant to benzylpenicillin, oxacillin; 7/11 of isolates were resistant to clindamycin, erythromycin, and trimethoprim-sulfamethoxazole; All of the isolates (11/11) are multidrug resistance. Vancomycin, nitrofurantoin, linezolid, and quinupristin-dalfopristin are effective antimicrobial agents in treating S. epidermidis septicemia in Vietnamese cancer patients. The high level of methicillin and multidrug resistance limited the therapeutic options in Vietnamese cancer patients are causes of concern.
