Accumulation of lipids in Schistosoma mansoni sporocysts cultured in vitro

Major lipids and fatty acids in the liver and rumen fluid of the goat (Capra hircus) infected with the trematodeParamphistomum cervi

“…Vykhrestyuk & Yarygina (1975) reported 24.72 and 49.67% of PL in the total lipid of the cattle trematodes E. pancreaticum and P. cervi , respectively. Smith & Brooks (1969), Meyer et al (1970), DiConza & Basch (1976) and Rumjanek & Simpson (1980) reported that the percentage of phospholipids in TL of S. mansoni was 36–37 while the percentage of phospholipid in TL of G. hominis was 12.6 (Yusufi & Siddiqi, 1977).…”

“…The total lipid content of trematodes varies among species. Lipid contents have been investigated from some of the following important species: Fasciola hepatica (Hrzenjak & Ehrlich, 1975; Chappell, 1980); Paramphistomum microbothrium (Hrzenjak & Ehrlich, 1975; Awharitoma et al , 1990); Cotolyphoron cotolyphorum (Yusufi & Siddiqi, 1976); Clonorchis sinensis (Lee et al , 1977); Schistosoma mansoni (Smith & Brooks, 1969; Meyer et al , 1970; DiConza & Basch, 1976; Rumjanek & Simpson, 1980; Furlong, 1991); Echinostoma trivolvis (Fried et al , 1993) and Paramphistomum cervi (Vykhrestyuk & Yarygina, 1975; Ghosh et al , 2005). Major lipid classes and fatty acids were reported in these studies.…”

The role of trematode parasites as a nutritional food source for higher trophic level consumers

“…The estimations for R. ondatrae cercariae were relatively close for both the gravimetric method and the concentration curve (calibration method), which suggests that the binning technique may be useful to estimate lipid poor and rich cercariae (Fig. (Moore and Halton 1975;Diconza and Basch 1976;Furlong et al 1972;Xu et al 1994;Marsit et al 2000a), but this is the first to quantitatively estimate fluorescence values based on lipid composition.…”

“…Moore and Halton (1975) histochemically observed the presence of scattered FA in the rediae of Fasciola hepatica, as well as neutral lipid deposits and low FA levels in the cercariae. Diconza and Basch (1976) observed diffused lipids in the mother and daughter sporocysts of S. mansoni. Fried et al (1998b) investigated the differences in lipid content of various cercariae species, observing a range from none found in Z. lunata, to ORO-positive droplets in the excretory system of Ribeiroia sp.…”

“…Early investigations of their composition have been largely qualitative and determined that they contain lipids and are glycogen-rich, suggesting that they are nutritious (Moore and Halton 1975;Diconza and Basch 1976;Fried et al 1998a;Furlong et al 1992;Nanduri et al 1991;Xu et al 1994). These efforts have primarily employed the use of Oil Red-O (ORO), and Nile Blue Sulphate as means to stain and visually detect the presence of neutral lipids and FA in rediae, cercariae and sporocysts of various trematode species.…”
