Fig 3. SB203580 decreases parasite motility.

(A) Effect of SB203580 on sporozoite trail deposits during parasite gliding. Treatment: sporozoites placed on glass slides covered with gelatin were incubated for 1 h in the presence of SB203580 (25 μM) or DMSO. Pre-treatment: Sporozoites were first treated with SB203580 (25 μM) or DMSO for 1 h; after chasing, the sporozoite suspension was placed on glass slides for 1 h. After fixation, deposited molecules forming trails were revealed by immunofluorescence using a mouse polyclonal antibody against E. tenella sporozoites. Pictures are representative of 3 independent experiments. (B) Effect of SB203580 on sporozoite motility. Sporozoites were treated or pre-treated as described in (A). In this experiment, sporozoite gliding motility was assessed by videorecording and quantified by counting motile sporozoites over a period of 30 s. Data represent the mean of 6 independent experiments ± SEM. Statistical significance was calculated using the Student t test: *P < 0.05.
