Figure 2. Δcwp1 pseudocysts lack a protective CW.

Figure 2

(a) Bright field microscopy: WB and Δcwp1-derived cysts/pseudocysts were tested for resistance to water (upper panels) and PBS (lower panels). WB cysts show refractile CWs; this optical effect is absent in Δcwp1 pseudocysts that appear damaged after exposure to water. Insets: individual cysts/pseudocysts. Scale bar: 25 μm. (b) tEM analysis: typical appearance of CWs (WB left panel); Δcwp1 pseudocysts lack a CW completely. Scale bar: 1 μm. Arrows indicate partially disassembled cytoskeletal elements. Insets scale bar: 0.2 μm. (c) AO/EB testing for cyst/pseudocyst viability highlights the fragility of cell culture-derived Δcwp1 pseudocysts compared with WB cysts. The y-axis indicates percentage.
