Carbapenem-resistant Citrobacter amalonaticus and VRE bacteraemia in an immunocompetent patient after a urological Rezum procedure.

In this report, we discuss the case of a 62-year-old man who presented with gross haematuria, fever, and chills 1 day after undergoing a Rezum procedure and was found to have carbapenem-resistant Citrobacter amalonaticus and vancomycin-resistant Enterococcus faecalis bacteraemia. The patient was treated with daptomycin, eravacycline, and ceftalozane-tazobactam with positive results. We discuss our case and treatment of C. amalonaticus bacteraemia, a pathogen with limited existing literature on its incidence, presentation, and treatment.
