Once within the snail, successful miracidia
transform into a sporocyst, a sac-like structure that generates genetically identical cercariae (another small, swimming larvae--see Figure 1), which emerge periodically from infected snails to seek out the next host in the parasite's life cycle.
by a stool-hatching method, and no active miracidia
Rearing and infection of the experimental snails: From the progeny of the susceptible and resistant groups, 100 young susceptible (subgroup Ia) and 100 young resistant (subgroup II a) snails were infected by individual exposure to 8-10 vigorously swimming freshly hatched miracidia
in palettes, each palette was with six wells, each well accommodated one snail with 2 mL of de-chlorinated tap water.
We found little evidence supporting the hypothesis that the viability of miracidia
and metacercariae of F.
In the environment, eggs hatch into miracidia
, which asexually reproduce within the terrestrial snail intermediate host after burrowing into its muscular foot.

and on their physiological parameters.

The vaccine constructs are SjCTP1-Hsp70 and SjC23-Hsp70; the former was reported to be more successful as it produced a worm burden decrease of 51.2%, liver egg decrease of 61.5%, faecal waste egg reduction of 52.1%, and 52.1% decrease in hatching faecal miracidia
The effect of environmental factors on the development behaviour and survival of Paramphistomum microbothrium miracidia
natalensis was exposed to miracidia
from eggs of Fasciola gigantica that were obtained from the slaughterhouse in Cotonou.
In addition, the ovicidal action of PZQ caused inviability of eggs by retraction of miracidia
, mostly of mature eggs.
in turn infect freshwater snails, where they become sporocysts, which in turn produce many more sporocysts by cell division.
