Elizabethkingia miricola bacteraemia in a haemodialysis patient

We report a case of catheter-associated Elizabethkingia miricola bacteraemia in a haemodialysis patient. The patient was a 73-year-old home haemodialysis patient who presented with a history of recurrent falls and fevers. Blood cultures grew Gram-negative bacilli identified by MALDI-TOF MS (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry 6903 MSP Library) and 16S rRNA gene sequencing as E. miricola. E. miricola is an emerging human pathogen and is multidrug-resistant, making the choice of antimicrobial therapy challenging. There are only a small number of case reports of human infection worldwide and this is the second reported case of catheter-related bacteraemia. It has also been found in the hospital environment in South Korea and is pathogenic in black-spotted frogs.
