Molecular and virulence differences of Klebsiella pneumoniae isolated from blood

This study provided important insights into the diversity between <i>K. pneumoniae</i> strains isolated from blood in the same hospital. <i>K. pneumoniae</i> isolated from different patients has diversity of drug resistance genes, virulence genes and plasmids, which may affect the outcome of patients. Therefore, accurate treatment of patients according to the molecular characteristics and drug resistance phenotype of the isolates will achieve better efficacy.
