Erythrocytic schizogony is where the micro-metacryptozoites after escaping into the blood stream, invade the erythrocytes. Each become rounded and modified into a young trophozoite. As it grows in size, a central vacuole is developed and the nucleus is pushed to one side into the peripheral cytoplasm. This stage is clinically referred to as the signet ring stage, as it resembles the signet ring with the peripherally located nucleus looking like a gem of the ring.
