Characterization of pEncl-30969cz, a novel ColE1-like plasmid encoding VIM-1 carbapenemase, from an Enterobacter cloacae sequence type 92 isolate.

A VIM-1-producing ST92 Enterobacter cloacae was isolated in a Czech hospital. blaVIM-1 was part of the class 1 integron In110 carried by a Tn1721-like transposon. Tn1721-like was located on a ColE1-like plasmid, pEncl-30969cz (33,003 bp). Target site duplications at the boundaries of Tn1721-like suggested its transposition into the pEncl-30969cz backbone.
