Donor-derived transmission through lung transplantation of carbapenem-resistant Acinetobacter baumannii producing the OXA-23 carbapenemase during an ongoing healthcare facility outbreak.

We describe a rare instance of donor-derived OXA-23-producing carbapenem-resistant Acinetobacter baumannii transmission during lung transplantation and the subsequent public health response. This investigation highlights how transplantation can introduce rare multidrug-resistant organisms into different healthcare facilities and regions.
