Sequence types 235, 111, and 132 Predominate among multidrug-resistant Pseudomonas aeruginosa clinical isolates in croatia

Abstract

A population analysis of 103 multidrug-resistant Pseudomonas aeruginosa isolates from Croatian hospitals was performed. Twelve sequence types (STs) were identified, with a predominance of international clones ST235 (serotype 011 [41%]), ST111 (serotype 012 [15%]), and ST132 (serotype 06 [11%]). Overexpression of the natural AmpC cephalosporinase was common (42%), but only a few ST235 or ST111 isolates produced VIM-1 or VIM-2 metallo - β -lactamases or PER-1 or GES-7 extended-spectrum β-lactamases.Copyright
