The eggs enter the water, and hatch into a miracidium larva within 2 weeks.

In the presence of open water, the eggs will hatch and the miracidium stage of life is reached again.

Miracidium is induced to hatch when ripe eggs are released from the worm into water.

He gave a comparative description of the egg and miracidium of the fluke.

Fully developed miracidium releases the operculum of the egg using several proteases.

The first snail host is penetrated by a miracidium, producing a sporocyst.

Following this a miracidium hatches, which swims to find a mollusc host.

After infection, close to the site of penetration, the miracidium transforms into a primary (mother) sporocyst.

The eggs hatch into a miracidium stage, which develops into multiple sporocysts.

The parasite's eggs hatch in the water and the miracidium invades the foot of the snails.

Inside the snails gut, the miracidium becomes a sporocyst which then begin to produce rediae.

From a single miracidium result a few thousand cercaria, every one of which is capable of infecting man.

The miracidium grows into the sporocyst stage.

During the embryonation of the egg, a larva called a miracidium develops from germinal cells.

Inside the snail, the miracidium sheds it epithelium and develops into a mother sporocyst.

The egg becomes a miracidium with an operculum, which penetrates a snail, the first intermediate host.

Within the visceral mass of Dreissena, the miracidium transforms into a mother (primary) sporocyst.

The miracidium develops into a sporocyst, which in turn house the asexual reproduction of redia, the next stage.

The miracidium penetrates the soft tissues of the snail, where it metamorphoses into a sporocyst.

Some very fortunate eggs get swallowed by a snail and here they hatch into tiny, transparent larva (miracidium).

The larvae (or miracidium) drill through the wall of the gut and settle in its digestive tract, where they develop into a juvenile stage.

After attaching to a suitable snail host, the miracidium penetrates into the snail body.

The first larval stage is the miracidium, and are found to be attracted to macrocmolecular glycoconjugates associated with a possible snail host.

The Miracidium of C. marginatum.

Embryonated eggs are passed into an aquatic environment (fresh or brackish water) each containing a fully developed larva, called a miracidium.
