Spiral-shaped bacteremia: Difference in the duration of blood cultures between Helicobacter spp. and Campylobacter spp. using the BACTEC system.

Although spiral bacteria are uncommon, they cause bacteremia. We evaluated their characteristics, in particular, the time from the start of blood culture to the first report of a positive result to physicians, using the BACTEC blood culture system. In cases of spiral bacteremia, an extended treatment period should be considered.
