Acquisition of a transposon encoding extended-spectrum beta-lactamase SHV-12 by Pseudomonas aeruginosa isolates during the clinical course of a burn patient.

ABSTRACT: Three of seven clonally related Pseudomonas aeruginosa strains isolated from a burn patient produced the extended-spectrum beta-lactamase (ESBL) SHV-12. Its gene was flanked by two IS26 elements with a large transposon (>24 kb). The transposon also contained at least five IS26 elements and a gene encoding the amikacin resistance determinant aminoglycoside 6'-N-acetyltransferase type Ib [aac(6')-Ib]. It was inserted into the gene PA5317 in the P. aeruginosa chromosome.
