New Delhi metallo-β-lactamase (bla(NDM)) acquisition by Gram-negative bacteria is a primary concern due to its broad-host-range distribution. This study investigated two potential in-vivo horizontal gene transfers (HGTs) of bla(NDM) between Enterobacterales and Pseudomonas aeruginosa, initially indicated by polymerase chain reaction. Whole-genome sequencing showed independent parallel acquisition of two different bla(NDM) variants (NDM-1 and NDM-5) in P. aeruginosa and Enterobacterales, respectively. The data show that short-read sequencing provides the necessary resolution to confirm or dispute HGT by the comparison of genetic elements surrounding the gene of interest, and thus provide a timely response to potential outbreaks.
