Germinal Development in the Mother Sporocyst and Redia of Halipegus eccentricus Thomas, 1939

Journal of Parasitology, 1949
In recent studies of germinal development in rediae (Cort, Ameel, and Van der Woude, 1948) it was found that in a psilostome and several echinostome species well developed germinal masses were present in the posterior end of the body cavity of both mother and daughter rediae.

Fasciola hepatica  : in vitro production of daughter rediae and cercariae from first- and second-generation rediae

Parasitology Research, 1997
Fasciola hepatica mother rediae belonging to the first generation and the first cohort of the second generation were extracted from their snail intermediate host (Lymnaea truncatula) and maintained in vitro for 16 days to determine the quantity of daughter rediae and cercariae produced by each generation.

Hemozoin formation in Echinostoma trivolvis rediae

International Journal for Parasitology, 2005
Rediae of the trematode Echinostoma trivolvis, from naturally infected Helisoma trivolvis snails, form a black pigment while inside the snail host. Here we examine the black pigment to show that the insolubility characteristics in detergent and weak base solution are identical to Plasmodium falciparum hemozoin. Laser desorption mass spectrometry of the

A histochemical study of the rediae and cercariae of Fasciola hepatica

Zeitschrift f�r Parasitenkunde, 1975
Histochemical studies have revealed hydrolytic enzyme activity in the redial tegument and caecal epithelium of Fasciola hepatica. A number of the hydrolases are known to be lysosomal marker enzymes and it is thought that they may be involved in intracellular digestion.

In vitro survival of rediae of Cyclocoelum microstomum

Experimental Parasitology, 1956
Abstract 1. 1. A method is described for obtaining axenic miracidia and rediae of Cyclocoelum microstomum . 2. 2. Rediae were maintained in various culture media for as long as 14 days, but no appreciable growth or development occurred.

Echinostome rediae: Effect of pretreatment with cold on transplantation to uninfected snails

Experimental Parasitology, 1975
Abstract When donor snails, Lymnaea stagnalis , infected with Echinoparyphium aconiatum were held at 13 C for at least 24 days, transplantation of newborn rediae from them to uninfected snails was 2.5 times as successful as when donor snails were held at 23 C.

Germinal Material in the Rediae of Clinostomum marginatum (Rudolphi)

The Journal of Parasitology, 1950
Krull (1934) and Hunter and Hunter (1934 and 1935a) determined that the cercaria of Clinostonmun marginatunz is a fork-tailed form that develops in rediae. The cercariae penetrate various species of fish and develop into large metacercariae, popularly known as "yellow grubs," which attain almost adult size.

Neutral Lipids in Cercariae, Encysted Metacercariae, and Rediae ofZygocotyle lunata

Journal of Parasitology, 2000
High-performance thin-layer chromatography was used to analyze the neutral lipids in the rediae, cercariae, and encysted metacercariae of the paramphistomid trematode Zygocotyle lunata. Visual observations of the chromatograms showed that the most abundant lipid fractions were free sterols and free fatty acids in all larval stages and triacylglycerols ...

Development of the Mother Sporocyst and Rediae of Paragonimus kellicotti Ward, 1908

The Journal of Parasitology, 1951
Ameel (1934) worked out the life cycle of Paragonimus kellicotti in experimental infections of Pomatiopsis lapidaria. Later, Chen (1937) made a study of the germ cell cycle of this species in which she followed the germinal cells in sections through all the stages of development.
