Summary: | Background: Pseudomonas mendocina is a gram-negative bacterium belonging to the Pseudomonas genus. It rarely causes infection in humans. To date, there have only been fourteen previous cases of Pseudomonas mendocina infection published worldwide.Case report: Here, we present the case of a 64-year-old man, with a complex past medical history, who presented to a UK hospital with signs of sepsis, including high-grade fever. Admission bloods showed raised inflammatory markers consistent with infection. On day two of admission, blood cultures tested positive for Pseudomonas mendocina, as confirmed by MALDI-TOF. Results: The patient received intravenous piperacillin/tazobactam, based on antimicrobial sensitivities, and made a good clinical recovery. He was discharged home after two weeks in hospital. Conclusion: In conclusion, we present the first reported UK case of Pseudomonas mendocina bacteraemia, adding further data regarding the epidemiology, pathogenesis and clinical treatment of this unusual infection.
