This case report describes a strain of K. pneumoniae, referred to as hypermucoviscous, that is distinctly different from CRE. Hypermucoviscous K. pneumoniae, unlike CRE, is community acquired, highly virulent and essentially pansensitive.[2] Hypermucoviscous K. pneumoniae causes invasive infections, including liver abscess, endopthalmitis, meningitis, empyema, and necrotizing fasciitis, that occur primarily in Southeast Asia. Here we report a case of monomicrobial necrotizing fasciitis caused by hypermucoviscous K. pneumoniae in a Filipino woman who presented to our public hospital in Oakland, California. While there have been limited reports of infection with this unusual K. pneumoniae strain outside of Asia, to our knowledge this is the first report of necrotizing fasciitis caused by confirmed hypermucoviscous K. pneumoniae in North America.
