Our data showed higher resistance rate to carbapenem even compared to previous reports.
The vast majority of our isolates were XDR with high resistance to colistin.
High resistance to colistin and polymixin is alarming due to limited antibiotic prescription for <em>A. baumanniiem> infections.
This is the first report about the prevalence of <em>A. baumannii carrying blaSPMem>, <em>blaGIMem> and <em>blaSIMem> genes from Iran.
