Abstract
INTRODUCTION:
The objective of this study was to characterize genes of aminoglycoside modifying enzymes (AMEs) in colonizing and infecting isolates of E. aerogenes harboring bla KPC from patients at a public hospital in Recife-PE, Brazil.
METHODS:
We analyzed 29 E. aerogenes clinical isolates resistant to aminoglycosides. AMEs genes were investigated by PCR and sequencing.
RESULTS:
Colonizing and infecting isolates mainly presented the genetic profiles aac(3)-IIa/aph(3’)-VI or ant(2”)-IIa/aph(3’)-VI. This is the first report of aph(3’)-VI in E. aerogenes harboring bla KPC in Brazil.
CONCLUSIONS:
The results highlight the importance in establishing rigorous methods for the surveillance of resistance genes, especially in colonized patients.
