We describe a case of "Flexispira rappini"
bacteremia from a 9-year-old girl who presented with a 5-day history of
fever, productive cough, and malaise. A chest X-ray result was
compatible with right middle lobe pneumonia. Blood culture grew a
gram-negative spiral fusiform bacterium 2 days after the inoculation.
Biochemical tests showed the organism to be catalase negative, oxidase
positive, sodium hippurate hydrolysis negative, and urea hydrolysis
negative. 16S rRNA gene sequencing identified this organism as
"F. rappini," showing a six-base substitution from the
type strain. This is the first report of "F. rappini"
bacteremia in a human, suggesting that this organism has the potential
of causing invasive infection, but its role in pneumonia is uncertain
and could be unrelated to the bacteremia.
