Molecular and genomic epidemiology of VIM/IMP-like metallo-β-lactamase-producing Pseudomonas aeruginosa genotypes in Poland.

Together with a previous report on self-transmissible In461-carrying IncP-2-type plasmids, this study revealed the molecular/genomic background of the rapid MPPA increase in Poland in 2001-15, evidencing multi-clonal spread as its leading factor. Numerous novel/specific MPPA characteristics were identified.
