Emergence of 16S rRNA methylase gene armA and cocarriage of blaIMP-1 in Pseudomonas aeruginosa isolates from South Korea

Abstract Of the 100 multidrug-resistant Pseudomonas aeruginosa isolates from a Korean hospital, 14 isolates that were resistant to all aminoglycosides tested carried 16S rRNA methylase gene armA . Fourteen armA -positive isolates were classified into 8 pulsotypes. Seven armA -positive isolates cocarried bla IMP-1 . This study is the first report of occurrence of armA in P. aeruginosa .
