Fasciola hepatica cystatins: recombinant production, biochemical characterisation and efficacy as vaccines
… with the digenetic trematode (flatworm) Fasciola hepatica, is of major global economic importance in ruminants, such as cattle and sheep, and is now recognised as an important zoonosis. Following ingestion by the mammalian host, the parasite migrates through the intestinal wall and …

Απομόνωση και ταυτοποίηση δευτερογενών μεταβολιτών από το φαιοφύκος Dictyota fasciola από τα Πούλιθρα
… οργανικού εκχυλίσματος του φαιοφύκους Dictyota fasciola, βιομάζα του οποίου συλλέχθηκε στα Πούλιθρα της Πελοποννήσου. Μετά από εξαντλητική εκχύλιση του οργανισμού με οργανικούς διαλύτες, το εκχύλισμα υποβλήθηκε σε διαδοχικούς χρωματογραφικούς διαχωρισμούς. Από τη διαδικασία αυτή απομονώθηκαν …

Post-genomic studies on the neuropeptide signalling system of Juvenile <i>Fasciola hepatica</i>
The flatworm Fasciola hepatica is a globally significant parasite in terms of agricultural productivity and human health. This thesis investigated the role of the neuropeptide signalling system in the biology of this species. Advances in genomic and transcriptomic resources facilitated the …

The cellular and molecular origins of extracellular vesicles secreted by <i>Fasciola hepatica</i>
Parasitic helminths maintain chronic infections in the host by secreting molecules that promote parasite survival. These molecules can be packaged into extracellular vesicles (EVs) which are internalised by host cells and exert potent immunomodulatory effects. Thus, blocking helminth (h)EV release …

Characterisation of the Fasciola hepatica miRNome and an evaluation of its role in the host-parasite relationship
The liver fluke, Fasciola hepatica, is recognised as one of the most successful parasites worldwide due to its remarkable capacity to infect every mammal it encounters. For this reason, liver fluke disease, or fasciolosis, has the widest geographical spread of any parasite disease and contributes …

Evaluating the Feasibility of Rearing Juvenile Freshwater Mussels in a Flow-Through Pond System at White Sulphur Springs National Fish Hatchery
… freshwater mussels of Villosa iris and Lampsilis fasciola. Survival did not differ significantly (p = 0.1910) over 93 d for V. iris cultured with silt (mean 49.8% ± SD 14.5) and without (mean 32.9% ± SD 11.7). Survival differed significantly (p <0.0001) between juveniles of V. iris (mean 49.8% ± …

Genetics, demography and modeling of freshwater mussel (Bivalvia: Unionidae) populations in the Clinch River, U.S.A.
… E. capsaeformis, and a common species Lampsilis fasciola, in the Clinch River, TN, by screening mitochondrial DNA (mtDNA) sequences and nuclear DNA microsatellites. These species use fish hosts with varying dispersal capabilities, ranging from low, moderate, and high, respectively. Patterns of …

Liver fluke development: a target for parasite control?
… by flatworm parasites belonging to the genus Fasciola, is a prominent threat to global food security due to its widespread infection of agriculturally significant ruminants. Recent studies have identified a population of proliferative cells within Fasciola hepatica (Fasciola proliferative …

Stunting in pre-school and school-age children in the Peruvian highlands and its association with Fasciola infection and demographic factors
… for complete cell count and FAS2 ELISA for Fasciola antibodies. Three stool samples per participant were tested for parasites by Kato-Katz and Lumbreras rapid sedimentation methods. Chronic fascioliasis was determined by the presence of ova in stool. Children's height, weight, and age were …

Propagation of Juvenile Freshwater Mussels (Bivalvia: Unionidae) and Assessment of Habitat Suitability for Restoration of Mussels in the Clinch River, Virginia
… and wavyrayed lampmussel (Lampsilis fasciola). This experiment was prematurely terminated due to predation on mussels by fathead minnows (Pimephales promelas). Experiment 2 evaluated growth and survival of juvenile rainbow mussels in outdoor troughs and indoor aquaria. There was no …

Population demographics of six freshwater mussel species (Bivalvia: Unionidae) in the upper Clinch river, Virginia and Tennessee
… of enrichment. Growth rates of female Lampsilis fasciola were significantly less than growth rates of male L. fasciola after 3 years of age, probably due to the onset of sexual maturity. Age-class distributions revealed an absence of recruited juveniles at the Slant site (RK 359.3) after 1977 to …

Release of Juvenile Mussels into a Fish Hatchery Raceway: a Comparison of Techniques
… Juvenile wavyrayed lampmussels (<I>Lampsilis fasciola</I>) were artificially propagated in the laboratory and subsequently release into a fish hatchery raceway during June, September and March. Juveniles released in June experienced a gradual decline in survival rate, with 50% survival after …

The immunomodulatory properties of helminth-derived products on dendritic cell maturation and function
… products derived from the helminth parasites Fasciola hepatica and Ascaris lumbricoides we investigated the mechanism by which these responses are induced. Dendritic cells (DC’s) play a crucial role in linking the innate to adaptive arms of the immune system and directing the subsequent immune …
