The effects of a 5 versus 25 miracidia exposure of Echinostoma caproni on the lipid composition of Biomphalaria glabrata was studied using high performance thin layer chromatography (HPTLC)-densitometry. A 50 miracidia dose was not used because such a high level of exposure caused severe snail mortality by 3 weeks post-exposure (PE). Lipids were determined in the digestive-gland gonad complex (DGG) of the exposed snails and in the uninfected matched controls at 2 and 4 weeks PE. Extraction of lipids from DGGs was carried out by the Folch method with chloroform-methanol (2:1), and extracts were analyzed on Analtech HPTLC-HLF pre-adsorbent silica gel plates with measurement of separated bands using a CAMAG Scanner 3. For neutral lipids the mobile phase was petroleum ether-diethyl ether-glacial acetic acid (80:20:1) and the detection reagent was 5% ethanolic phosphoric acid, and for polar lipids chloroform-methanol-deionized water (65:25:4) mobile phase and 10% cupric sulfate in 8% phosphoric acid detection reagent were used. No significant differences in the concentrations of free sterols, free fatty acids, triacylglycerols, phosphatidylcholine, and phosphatidylethanolamine were seen at 2 weeks PE in any of the groups. At 4 weeks PE, the free fatty acid concentration increased significantly in the snails exposed to 25 miracidia compared to that of the 5 miracidia/snail group or the controls. Elevation of the free fatty acid fraction in the high dose snail group suggested that some changes occurred in the lipid metabolism of the snails in that group as a function of miracidia dose.

The lectin binding properties of Fasciola hepatica miracidia were studied by a panel of fluorescein- and gold-conjugated lectins (ConA, LCA, WGA, LEA, SBA, HPA and UEA-I). The presence of mannose and/or glucose residues was demonstrated with ConA and LCA as weak diffuse fluorescence of the miracidial surface, which was more intense at the anterior part of the larva. The N-acetylglucosamine-binding lectins WGA and LEA reacted intensely with the whole miracidial surface. No labelling with N-acetylgalactosamine and/or galactose-specific (SBA and HPA) and fucose-specific UEA-I lectins was observed. The possibility that the specific recognition of the miracidial surface carbohydrates by lectins may initiate the process of transformation of the miracidia into sporocysts was examined in vitro in physiological saline for Galba truncatula. Incubation in the presence of ConA and WGA resulted in facilitation of the transformation process. Facilitation was absent in the presence of inhibitor sugars. Incubation in the presence of SBA or UEA-I had no effect. The results suggested a possible impact of carbohydrate-lectin interactions in transformation of miracidia of F. hepatica to sporocysts in vivo.

The life cycle of Echinoparyphium rubrum (Cort, 1914) comb. n. has been completed experimentally. All of the developmental stages - egg, miracidium, sporocyst, mother and daughter rediae, cercaria, metacercaria, and adult - were examined and described. The miracidia infected freshwater snails of the genus Physa, P. gyrina and P. occidentalis. Attempts to infect snails of the genera Lymnaea, L. auricularis, L. peregra, L. truncatula and Bulinus, B. truncatus failed. Cercariae infected various pulmonate and prosobranch freshwater snails, mussels, frogi water turtles and planarians. The adults developed in the small intestine of birds and mammals. The identity and major characteristics of Echinoparyphium rubrum are discussed. Synonyms of E. rubrum are Cercaria rubra Cort, 1914; Cercaria biflexa Faust, 1917; Cercaria chisolenata Faust, 1918; Echinostoma callawayensis Barker et Noll, 1915; Echinostoma revolutum of Johnson (1920); Echinoparyphium elegans of Cannon (1938), of Bain and Trelfall (1977), of Mahoney and Trelfall (1977); and Echinoparyphium recurvatum of Jilek (1977), Harley (1972), Sankurathri and Holmes (1976). Comparisons are made between E. rubrum and its 43-collar-spined allies: E. flexum from North America, E. cinctum from Europe, E. dunni from Asia and E. elegans from Africa.
