FIG. 7.
ospE expression levels among B. lusitaniae isolates. Illustrated are quantitative real-time PCR results from spirochetes grown at 33°C and harvested at mid-logarithmic growth phase. The relative expression levels of the ospE gene are presented as copies of ospE transcript per 102 copies of the constitutively expressed B. lusitaniae flaB gene. Each experiment was performed at least two times in triplicate, and error bars represent standard deviations (SDs).
