In-host evolution of classic to convergent Klebsiella pneumoniae sequence type 147 isolates and impact of associated capsular changes on different morphotypes

This study investigates in-host evolution of Klebsiella pneumoniae sequence type 147 isolates, revealing microevolution from classic to convergent pathotype through plasmid acquisition and capsular changes affecting virulence and morphology.

Temperatures above 37°C increase virulence of a convergent Klebsiella pneumoniae sequence type 307 strain

This study shows that temperatures above 37°C increase hypermucoviscosity and virulence in a convergent Klebsiella pneumoniae strain, potentially due to plasmid-encoded factors and temperature-dependent regulatory changes.

Klebsiella pneumoniae exhibiting a phenotypic hyper-splitting phenomenon including the formation of small colony variants

The paper describes a Klebsiella pneumoniae strain exhibiting phenotypic hyper-splitting, forming small colony variants and multiple morpho-resistotypes with clinical implications.
