Pathogenesis

Pathophysiology

  • Transmitted by ingesting either sporulated oocysts or sporozite-infected mice (direct and indirect life cycles).
  • After ingestion, sporulated oocysts excyst in the presence of bile and sporozoites are released.
  • Sporozoites invade intestinal wall.
  • Intestinal epithelial cells are destroyed by both shizogonous and gametogenous phases.
