The images were used to obtain the morphological and morphometric data on the cercariae
by processing with the iTEM software.
stagnalis species of mollusks, which are often infected with rediae and cercariae
To complete their stage of the transmission process, cercariae
must find and infect the second intermediate host, often a bivalve, crustacean or small fish.
In this context, the goal of the present work was to complete the description of the cercariae
found in the sampling of molluscs of this environment.
The pools of cercariae
used were (1) LE, SJ, and AL strains of S.
Snails which became infected in spring would begin shedding cercariae
~50 days post-infection when wetlands provide green vegetation during early fall senescence.
The destruction of the digestive gland was even more severe may be due to the developing of daughter sporocycts which contains many of the developing cercariae
In the absence of cercariae
exit, the compression method with the subsequent microscopy was applied [2,3].
, as prevalence of this parasite in both hosts is quite similar (Table I).
(4) Humans get infected with this disease when they make contact with water contaminated with the skin-penetrating cercariae
. Prevalence of schistosomiasis, at present, is still high in sub-Saharan Africa.
Another common cause of seasonal clusters of pruritic rashes may be caused by aquatic exposures to the infective stage cercariae
of several avian schistosomes, or flatworms, that are released into freshwater lakes and rivers in the tens of thousands by infected aquatic snail intermediate hosts in a complicated life cycle (Figure 2).
