First Detection of Colistin-Resistant in Association with Carbapenemase Isolated from Clinical Lebanese Patients.

This study aims to describe the molecular mechanisms of carbapenem and colistin resistance in strains isolated from hospitalized patients in Lebanon. We report in this study the first description of producing carbapenem-resistant ST383, as well as the presence of two out of five isolates resistant to colistin due to mutations in the amino acid sequences of proteins (, , and ). Therefore, screening of such isolates may be effective in limiting the spread of these resistant microorganisms in hospitalized patients and within the community.
