Fig. 2From: Phenotypical profile and global transcriptomic profile of Hypervirulent Klebsiella pneumoniae due to carbapenemase-encoding plasmid acquisitionThe mucoviscosity and capsular polysaccharide (CPS) production. a The results of mucoviscosity. The string test was used to assess the hypermucoviscosity of K. pneumoniae strains. A string of 5 mm or longer is defined as positive. b CPS production. CPS biosynthesis in the K. pneumoniae strains was determined by phenol-sulphuric acid assays. P < 0.05 versus its plasmid-free isogenic ancestor. Error bars indicate the standard deviations for three triplicate samplesBack to article page
