Life Cycle
- The infective form of E. bieneusi is the resistant spore and it can survive for a long time in the environment.
- The spore extends its polar tubule and infects the host cell.
- The spore injects the infective sporoplasm into the eukaryotic host cell through the polar tubule.
- Inside the cell, the sporoplasm undergoes extensive multiplication either by merogony (binary fission) or schizogony (multiple fission).
- This development occurs in direct contact with the host cell cytoplasm. In the cytoplasm, microsporidia develop by sporogony to mature spores.
- During sporogony, a thick wall is formed around the spore, which provides resistance to adverse environmental conditions. When the spores increase in number and completely fill the host cell cytoplasm, the cell membrane is disrupted and releases the spores to the surroundings. These free mature spores can infect new cells thus continuing the cycle (Desportes 1985).

Famous quotes containing the words life and/or cycle:
“It’s not that we have too much mother, but too little father. We can’t forgive our mothers for taking the place of our fathers until we are ready to see that the point of a man’s life is to be a father and a mentor, and we can’t do that because we don’t know how we would be a father or a mentor when we never had one.”
—Frank Pittman (20th century)
“Oh, life is a glorious cycle of song,
A medley of extemporanea;
And love is a thing that can never go wrong;
And I am Marie of Roumania.”
—Dorothy Parker (1893–1967)
