Fig. 8. The effects of the site of origin of sporozoites on motility in the
presence of salivary gland homogenate. (A) Salivary gland-derived sporozoites.
(B) Oocyst- and hemolymph-derived sporozoites. The images represent
XY maximum projections of 140 time-lapse images acquired over
a 742 s period. The yellow outlined arrows show the direction of sporozotie
movement (green). The yellow solid arrows indicate the relative position of
the salivary gland homogenate. The white arrows indicate fluorescent beads
(b). Scale bars, 50 µm.
