Bacteria Resistant to Colistin Present Serious Clinical Challenge

Researchers at Emory Health Sciences microbiologists have detected "heteroresistance" to colistin, a last-resort antibiotic, in already highly resistant Klebsiella pneumoniae. Their study (“ Carbapenem-Resistant  Klebsiella pneumoniae Exhibiting  Clinically Undetected Colistin Heteroresistance Leads to Treatment Failure in a Murine Model of Infection ”) appears in  mBio .“Antibiotic resistance is a growing crisis and a grave threat to human health. It is pro
