Lung transplant recipients (LTR) with more complicated post-operative courses were more likely to develop enteric gram-negative (GNR) infections which led to increased post-transplant morbidities.

Pre-transplant GNR colonization was not a risk factor for GNR infection post-transplant.

Strategies to minimize post-transplant enteric GNR infections need further study.

A single-center retrospective study of LTR between January 2017 and October 2023 was performed.

Donor/recipient characteristics, microbiologic data, and 1-year clinical outcomes were analyzed.
