Image: A human neutrophil (grey) is interacting with Klebsiella pneumoniae (pink). A hypervirulent version of this pathogen is sparking increasing concern due to recent reports describing hypervirulent strains that are antimicrobial resistant (Photo courtesy of National Institute of Allergy and Infectious Diseases).

Biomarker Discovered for Hypervirulent Pathogen

There is no accurate method for distinguishing between the hypervirulent strain from the classical strain of Klebsiella pneumoniae (cKp), which is most often seen in the Western hemisphere, and is less virulent and usually causes infections in hospital settings. More...
