We did not observe emission of cercariae
during consumption of parasitized snails of the Mc and Gc classes.
In 1999, San Solomon Springs had the greatest percentage of snails containing rediae and cercariae
From the derivatives studied, 15 naphthoquinones blocked penetration by cercariae
when applied to the tails of mice 24 h prior to infection through the tail.
Extracts of Zingiber officinale (ginger) rhizome showed activity against Schistosoma mansoni miracidia and cercariae
During the summer of 1938, Byrd examined over 100 specimens of the aquatic snail Physa gyrina, and noted that 28 individuals were releasing one or more of five different species of trematode cercariae
Sporocysts and/or cercariae
were found in three of the 386 examined D.
This age-related relationship seems logical due to increased opportunity for exposure to cercariae
by mature host animals.
The initial 'classic' pathology in the course of schistosomal infection, cercarial dermatitis, is frequently missed as it will be mostly experienced during travel, with transient lesions caused by the infecting cercariae
on penetration of the skin.
of an Eygptian strain of S mansoni were obtained from SBSP/TBRI and used for infection immediately after shedding from Biomphalaria alexandrina snails.
were extracted for DNA and PCR's were performed for detection of Neorickettsia (16S rRNA gene), and for identification of digenean species (i.
A metal ring was placed on the abdomen and then filled with treated water containing infectious cercariae
of a Puerto Rican strain of S.
The snail excretes the cercariae
into the surrounding water.
Brittle stars, which transmit Fellodistomum metacercariae to plaice, become infected by feeding on cercariae
which develop in bivalve mollusks (Koie, 1980).
Onshore winds keep locally produced cercariae
in place while bringing in cercariae
produced in other areas, so they become more concentrated.
then mature into adult worms in the portal venous system.
