Infectivity, Growth, and Distribution of Echinostoma caproni (Trematoda) in the ICR Mouse
The Journal of Parasitology, 1991Host-parasite interactions of the intestinal trematode Echinostoma caproni were studied in ICR laboratory mice. All of 40 mice, each fed 25 metacercarial cysts of Echinostoma caproni, were infected 1-20 wk postinfection (PI) with a mean of 17.2 worms/host. At 24 and 29 wk PI only 2 of 6 mice (33%) were infected, with a mean of 4.2 worms/host. Mean body

Migration and Development of Mother Sporocysts of Echinostoma caproni (Digenea: Echinostomatidae)
The Journal of Parasitology, 1997Experimental infections of the mollusc Biomphalaria pfeifferi by Echinostoma caproni miracidia (Mi) were carried out in order to analyze the migration and development of mother sporocysts (MS) at 26 C. Miracidia penetrated different parts of the host's body, such as the mantle collar, the foot and head covering (including velum and tentacles), the ...

Effects of prolonged worm storage on the viability of Echinostoma caproni eggs
Parasitology Research, 2008This study examined the effects of long-term worm storage on the viability of Echinostoma caproni eggs. Gravid adults (referred to as worm carcasses or WCs) were maintained in Locke's 1:1 at 4 degrees C for 2, 4, 6, 8, 10, and 12 months prior to use.

Effects of Echinostoma caproni infection on the lipid composition of Biomphalaria glabrata
International Journal for Parasitology, 1989Abstract Thin-layer chromatography was used to study the effects of Echinostoma caproni infection on neutral lipids in Biomphalaria glabrata snails. There was a marked reduction in the triacylglycerol fraction of the digestive gland-gonad complex of experimentally infected snails compared to matched controls.

Studies on the reproductive capacity of Echinostoma caproni (Trematoda) in hamsters and jirds
International Journal for Parasitology, 1995Total egg output per infective stage inoculated was used as a measurement of the reproductive capacity in Echinostoma caproni infections in hamsters and jirds. Egg production per adult E. caproni recovered was comparable in the hamster and in the jird, but the reproductive capacity of E.

Pathological effects of Echinostoma caproni (Trematoda) in the domestic chick
Journal of Helminthology, 1989ABSTRACTDomestic chicks experimentally infected with Echinostoma caproni for 2 weeks showed a dilated ileum, unkempt feathers, watery diarrhoea, and weight loss. The ileum from infected and control chicks was fixed in 10% neutral buffered formalin, and prepared as 10 μm paraffin sections stained in haematoxylin and eosin, Papanicolau, periodic acid ...

Echinostoma caproni in mice: Studies on the attachment site of an intestinal trematode
International Journal for Parasitology, 1989During infection in mice Echinostoma caproni is attached to the mucosa of the small intestine with the ventral sucker (acetabulum). The morphology, histology and dynamics of attachment sites from primary infections were examined. The sites were highly characteristic microscopically, and consisted of a plug of grasped mucosa occupying the cavity of the ...

Single- and five-worm infections of Echinostoma caproni (Trematoda) in the icr mouse
International Journal for Parasitology, 1990Twenty-nine (64%) of 44 ICR mice fed a single metacercarial cyst of Echinostoma caproni and all of 23 mice each fed five cysts were infected with ovigerous worms at necropsy 2-4 weeks post-infection. Each host fed five cysts had two to five worms at necropsy, and all worms were either paired or clustered.

Age of Adult Worms of Echinostoma caproni Does Not Affect Development of Miracidia
Journal of Parasitology, 2005The effect of the age of adult Echinostoma caproni on egg development was studied. The percentage of fully developed miracidia was determined in eggs derived from adult worms obtained from laboratory mice at 2, 4, 6, and 8 wk postinfection (PI).

International Journal for Parasitology, 1989
Laboratory hamsters (Mesocricetus auratus) were experimentally infected with 75 +/- 15 metacercarial cysts of Echinostoma caproni. Worms were recovered from days 7 to 89 post-infection with eight to 90 (average 37) parasites in the small intestine. Worm wet weights averaged 0.85 mg at 10 days, 1.8 mg at 17 days, 3.4 mg at 45 days, and 7.7 mg at 89 days;
