Recurrent multidrug-resistant Salmonella enterica serovar Typhimurium bacteremia in a returned traveller.

Abstract

This case report describes a 68-year-old male with recurrent multidrug-resistant Salmonella enterica serovar Typhimurium bacteremia acquired during travel abroad. He experienced a recurrence of bacteremia without a clear source and was successfully treated with 10 weeks of intravenous ertapenem. Post hoc genome sequencing revealed an isolate bearing class A, C, and D extended-spectrum β-lactamases (ESBLs). A review of English- and French-language literature since 2000 revealed eight publications that discussed recurrent S. enterica serovar Typhimurium bacteremia. Patients with multidrug-resistant S. enterica serovar Typhimurium should be monitored frequently for recrudescence, even in the absence of risk factors.
