First report of a urinary Pseudomonas juntendi carrying blaNDM-1 and blaIMP-15 co-integrated into the chromosome via ICE-IS91 and integron-Tn402-like transposition modules
PJ1 represents the first urinary <i>P. juntendi</i> isolate carrying both <i>bla</i> <sub>NDM-1</sub> and <i>bla</i> <sub>IMP-15</sub> on a single chromosome. Its composite resistance island and strong colonization capacity suggest that <i>P. juntendi</i> may serve as an emerging reservoir for metallo-<i>β</i>-lactamase dissemination, posing potential clinical and epidemiological threats.
