Co-existence of OXA-48 and NDM-1 in colistin resistant Pseudomonas aeruginosa ST235

Abstract excerpt

Here, we presented 11 cases with colistin-resistant Pseudomonas aeruginosa infection and co-existence of OXA-48 and NDM-1 in the ST235 high-risk clone. The molecular analyses were performed by Sanger sequencing and RT–PCR. The eight patients (72.7%) had an invasive infection and three (27.3%) had colonization. The 30-day mortality rate was 87.5% (7/8). Three patients (37.5%, 3/8) received colistin therapy before...
