IS1999 increases expression of the extended-spectrum beta-lactamase VEB-1 in Pseudomonas aeruginosa.

ABSTRACT: The integron-borne bla(VEB-1) gene encodes an extended-spectrum beta-lactamase. This gene was associated mostly with IS1999 and rarely with an additional IS2000 element in Pseudomonas aeruginosa isolates from Thailand, whereas IS1999 was only very rarely associated with bla(VEB-1) in Enterobacteriaceae. Expression experiments and promoter study identified promoter sequences in IS1999 that increased the expression of VEB-1 in P. aeruginosa.
