Genetic Diversity of Polymyxin Resistance Genes in Klebsiella pneumoniae Clinical Isolates

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT This study investigates the genetic diversity and evolutionary mechanisms driving polymyxin resistance in Klebsiella pneumoniae, a critical priority pathogen. By analysing mgrB, phoPQ and pmrAB genes in susceptible (PM‐S) and resistant (PM‐R) populations through neutrality tests (Tajima D, Fu & Li's D) we uncovered polygenic adaptation and ...
