Effect of antisera against SprB on cell movement over agar. Cells of wild-type F. johnsoniae FJ1 in MM at a density of approximately 5 × 108 cells per ml were mixed with an equal volume of preimmune serum (A) or anti-SprB (B). Aliquots (2 μl) were spotted on MM agar-coated slides and incubated for 75 min at 25°C, and images were recorded using a Photometrics CoolSNAPcf2 camera mounted on an Olympus BH-2 phase-contrast microscope. Bar = 50 μm.
