PPEs and PCVs of AmStM-GFP needle-inoculated (A) (n=5), A. centrale needle-inoculated (B) (n=5), and AmStM tick transmitted calves (C) (n=14; 5 represented) during acute anaplasmosis. Animal identification numbers are indicated on each panel. Bacteremia (left axis, ■) is reported as percent parasitized erythrocytes as determined by microscopic evaluation of Giemsa-stained blood smears. PCV (right axis, ◆) was used to evaluate anemia during infection. The x-axis indicates days post-infection where day 0 is the day of needle inoculation (A, B) or the day of tick application (C). Axes values have been standardized to allow comparison between graphs.
