title: A blaVEB-1 variant, blaVEB-6, associated with repeated elements in a complex genetic structure.
abstract: bla(VEB-6) was found on the Proteus mirabilis chromosome in a context similar to those of bla(VEB-1a) and bla(VEB-1b), in a truncated gene cassette flanked by 135-bp elements and duplications of the 3'-conserved segment of class 1 integrons. A linked aacA4-aadB-dfrA1-orfC cassette array includes components of Tn1331, illustrating the complex mosaicism of multiresistance regions.
