Cross-infection of solid organ transplant recipients by a multidrug-resistant Klebsiella pneumoniae isolate producing the OXA-48 carbapenemase, likely derived from a multiorgan donor.

We describe two cases of bacteremic infections caused by a multidrug-resistant Klebsiella pneumoniae isolate producing the OXA-48 carbapenemase that occurred in two solid organ transplant (liver and kidney) recipients, which was apparently transmitted with the allografts. This finding underscores the risk of donor-derived infections by multidrug-resistant Gram-negative pathogens in solid organ transplant recipients and emphasizes the need for rapid screening of organ donors for carriage of similar pathogens.
