A and B, Ornithodoros turicata ticks feeding on JD03. The duration between tick placement (A) and repletion (B) was between 20–30 minutes. C, Subdermal hemorrhage on JD03 was seen at the site where ticks fed. D, Spirochetes were visualized in the blood within 6 days after the transmission-associated blood meal (D), and a 25-µm scale is shown. These results from JD03 were representative of those for the 3 other animals.
