Figure 2: Toxoplasma reactivation. (a) Toxoplasma cyst in brain with cyst wall (arrow) may contain hundreds of bradyzoites (H & E, ×400). (b) Toxoplasma cyst positive for T. gondii-specific immunostain (IHC, ×400). (c) Multiple tachyzoites, some under fission, in an infected host cell (TEM). (d) Reactivation leading to cyst rupture (arrows) and spilling of the tachyzoites. Marcophages with engulfted tachyzoites (circles) (H & E, ×1000). (e) Tachyzoites spilling out from ruptured cyst (arrow) (PAS, ×1000)
