First case of bacteraemia due to carbapenem-resistant bacteroides faecis

Abstract

Multidrug resistant (MDR) bacteria are increasingly observed in nosocomial and commu-nity-acquired settings. Anaerobes are no exception to this rule, but there are fewer reports of MDR in the scientific literature on anaerobes than there are for other bacteria. In this short case report, we describe the first case of bacteraemia caused by a multidrug-resistant Bacteroides faecis, which pro-duces a carbapenemase encoded by the blaCfiA gene. This bacteraemia followed a digestive surgery operation. Surprisingly, these findings did not lead to a change in antibiotic therapy, probably be-cause the patient’s clinical state had improved. Nevertheless this report calls for better knowledge of anaerobic bacteria and for a systematic antimicrobial stewardship procedure following bacterae-mia.
