Genomic surveillance detected clonal sequence type-361 isolates carrying , , , and from a patient in Ukraine and four wounded foreign soldiers evacuated to Germany. Isolates were non-susceptible to carbapenems, aminoglycosides, and cefiderocol and aztreonam/avibactam due to a PBP3 YRIN insertion and the AmpC β-lactamase. Coordinated surveillance efforts across civilian, military, and veteran healthcare systems are essential to prevent further spread as international volunteers return home after medical evacuation from Ukraine.

- * Post-2019 samples included 32 strains that carried new genetic features linked to resistance.
- * Phylogenetic analysis showed three sub-lineages of carbapenem-resistant strains primarily from Ukraine and Georgia, including a significant epidemic clone with all three key resistance genes, highlighting the need for effective infection control and global monitoring.
Objective: The aim: To study the influence of chemical, physical factors on the biofilm forming activity of P. aeruginosa, A. baumannii.
