MicuRx added that its new agent MRX-8 is designed to overcome the limiting nephrotoxicity of current polymyxins
While all 9 isolates were senstitive to Polymyxin
displayed strong activity against Enterobacteriaceae, with susceptibility rates of>90%, except for E.

At this time, CDC recommends that Enterobacteriaceae isolates with a colistin or polymyxin
B MIC >4 ftg/ml be tested for the presence of mcr-1; testing is available through CDC (5).

has also been reported by many authors (12,16) but in our study we did not notice any resistance to these antibiotic.
territories, and Canada said they had treated at least one MDR-GNB infection resistant to all antimicrobials tested except polymyxins
in the previous 12 months.
In order to deal with such situation Tigecycline, polymyxins
(colistin and polymyxinB) and Fosfomycin are considered possible candidate therapies for infections caused by CPE.
Treatment options for CRAb infections are scarce and generally employ polymyxins
