Characterization of the Complete Nucleotide Sequences of IMP-4-Encoding Plasmids, Belonging to Diverse Inc Families, Recovered from Enterobacteriaceae Isolates of Wildlife Origin.

ABSTRACT: The complete nucleotide sequences of six IMP-4-encoding plasmids recovered from Enterobacteriaceae isolates of wildlife origin were characterized. Sequencing data showed that plasmids of different incompatibility groups (IncM, IncI1, IncF, and nontypeable [including an IncX5_2 and two pPrY2001-like]) carried the bla_IMP-4-carrying integrons In809 or In1460. Most of the plasmids carried an mph(A) region, and chrA-like, aac(3)-IId, and bla_TEM-1b genes. Finally, plasmid analysis revealed the involvement of two different IS26- and Tn1696-associated mechanisms in the mobilization of IMP-4-encoding integrons.
