Liver abscess associated with an oral flora bacterium Streptococcus anginosus

Abstract

Viridans group Streptococcus, a bacterium of the oral flora has a low-virulence and rarely causes liver abscess. A 40-year-old male patient was admitted to the hospital complaining of high fever and malaise. A physical examination revealed poor oral hygiene; there were caries on many teeth, and he had hepatomegaly. A hepatic abscess was identified in his abdominal tomography. Streptococcus anginosus was isolated from the drainage material, and the bile ducts were normal in his MRI cholangiography. An immunocompetent case of liver abscess caused by Streptococcus anginosus originated most probably from oral flora is presented here.
