VIM-12, a Novel Plasmid-Mediated Metallo-β-Lactamase from Klebsiella pneumoniae That Resembles a VIM-1/VIM-2 Hybrid

Abstract
A transferable plasmid from Klebsiella pneumoniae carried a class 1 integron containing bla VIM-12 , a novel bla VIM -type gene, flanked by two copies of aacA7. bla VIM-12 was clustered between bla VIM-1 and bla VIM-2 and differed from bla VIM-1 by 18 nucleotides that were all located at the 3′ end and matched the corresponding nucleotides in bla VIM-2 . The bla VIM-12 -associated 59-base element was identical to that described in bla VIM-2 alleles.
