Retrospective study investigates clinical and molecular features of hypermucoviscous Klebsiella pneumoniae infections, indicating prevalent clones and resistance patterns.

Key Points

The study investigates the clinical and molecular characteristics of hypermucoviscous Klebsiella pneumoniae infections in Yantai, China.
Conducted a retrospective study at Yantai Yuhuangding Hospital
Analyzed clinical isolates of Klebsiella pneumoniae using a string test
Performed antibiotic susceptibility tests and whole-genome sequencing on isolates
Identified 88 hypermucoviscous isolates from 485 strains, accounting for 18.1%
Detected predominant clones K1/ST23 and K2/ST65 among hmKP isolates
Virulence genes rmpA, rmpA2, iuc, iro, peg-344, and clb were commonly found
All hmKP isolates carried multiple resistance genes, not correlating fully with antibiotic resistance phenotypes
Identified two hypervirulent carbapenem-resistant strains
