Pyogenic Liver Abscess, Bacteremia, and Meningitis with Hypermucoviscous Klebsiella pneumoniae : An Unusual Case Report in a Human T-Cell Lymphotropic Virus Positive Patient of Caribbean Origin in the United States

Abstract EN

Pyogenic liver abscess (PLA) is a potentially fatal disease.

Klebsiella pneumoniae (K.

pneumoniae) has replaced Escherichia coli (E.

coli) as the predominant causative organism for pyogenic liver abscess.

Over the years a unique form of community-acquired invasive K.

pneumoniae infection of the liver has been well described in Southeast Asia.

This has recently been linked to a virulent hypermucoviscous K.

pneumoniae phenotype and to a specific genotype, rmpA positive.

To our knowledge, we report the first case of PLA with bacteremia and meningitis in a Guyanese patient with the presence of rmpA-positive K.

pneumoniae with laboratory evidence in North America.
