Contribution

First reported case of Ewingella americana infection in a cancer patient undergoing chemotherapy in Türkiye.

Findings

The patient showed full recovery after treatment with ceftriaxone.

No further bacterial growth was observed in subsequent blood cultures.

Abstract

Human infections caused by Ewingella americana have been rarely described. We report a case of E. americana in a cancer patient undergoing chemotherapy, who developed sepsis during a red blood cell transfusion. This causative pathogen was identified through the patient’s blood culture. The patient was treated with ceftriaxone and showed complete clinical improvement, with no further growth of E. americana or other pathogenic isolates in subsequent blood cultures. To the best of our knowledge, this is the first reported case of E. americana infection in a cancer patient undergoing chemotherapy in Türkiye.
