Bacteria resistant to last-resort antibiotic missed by standard tests
Emory microbiologists have detected heteroresistance to colistin, a last-resort antibiotic, in already highly resistant Klebsiella pneumoniae, a bacterium that causes blood, soft tissue and urinary tract infections.
The results are published online in the journal mBio.
David Weiss, PhD, director of the Emory Antibiotic Resistance Center and a researcher at the Yerkes National Primate Research Center, and his colleagues previously observed heteroresistance to colistin in other bacteria, called Enterobacter. Dr. Weiss is also a faculty member in the IMP and MMG programs.
The first author of the paper is Immunology and Molecular Pathogenesis graduate student Victor Band.
