Bacteremia caused by a Helicobacter pullorum-like organism

Abstract

We report a case of bacteremia caused by a Helicobacter pullorum-like organism in a 35-year-old man with pyrexia of unknown origin. Culture of blood samples obtained at admission yielded a motile, spiral-shaped gram-negative rod, and 16S rRNA gene sequencing identified this organism as Helicobacter pullorum-like, showing 23 base differences compared with the recently described "Helicobacter canadensis" (a recently proposed group that had previously been classified within H. pullorum). We believe that this is the first report of bacteremia caused by this organism.
