Klebsiella michiganensis is a newly emerging human pathogen. We describe a case of bloodstream infection in an immunocompromised patient. The pathogen was repeatedly isolated from blood and one rectal swab, and was identified using routine standard procedures. Further investigations revealed that the K. michiganensis was multidrug resistant, carrying a plasmid harbouring a Klebsiella pneumoniae carbapenemase (KPC)-3 carbapenemase gene. This plasmid has been frequently encountered in K. pneumoniae isolates in Europe but has never been described in K. michiganensis.
