AbstractHelminths (parasitic worms) are among the most important groups of marine parasites. They include some turbellarians (most of which are free living), ectoparasitic flukes (Monogenea), endoparasitic flukes (Aspidogastrea and Digenea), the various cestodes including the Amphilinidea, Gyrocotylidea and Eucestoda, nematodes (roundworms) and ...

The Innate Allergenicity of Helminth Parasites
Clinical Reviews in Allergy & Immunology, 2004Helminth parasites are well known to induce an immune response in their hosts characterised by elevated IgE, peripheral blood or local tissue eosinophilia, and in some cases, intestinal mastocytosis. This immunological response has a strong T-helper 2 (Th2) cytokine bias and is reminiscent of the immunological constellation found in allergic diseases ...

Intermediary metabolism in parasitic helminths
International Journal for Parasitology, 1987Abstract This review is a survey of progress in the field of helminth intermediary metabolism since ICOPA V. Data on the catabolism and synthesis of carbohydrates, lipids, amino acids, proteins, nucleotides and nucleic acids are presented and discussed in relation to previous work. The large number of references cited reflects a continued interest of

The pathogenic helminth parasites of eels
Journal of Fish Diseases, 2007AbstractAlthough 63 and 55 species of helminths have been reported from each species of Atlantic eel and from 29 to 19 for each species of Pacific eel only the monogeneans Pseudodactylogyrus bini and P. anguillae and the nematode Anguillicola crassus, originally specific to species of Pacific eels, can be considered serious pathogens. None of the three

Regulatory Peptides in Helminth Parasites
1994Publisher Summary This chapter focuses on the regulatory peptides in helminth parasites. Regulatory peptides are a diverse group of biologically active peptides, usually of between 1–5 kDa molecular weight and 2–50 amino acid residues in length, that operate as neurohormonal mediators in intercellular communication.

Lipid Metabolism in Parasitic Helminths
1983Publisher Summary This chapter discusses lipid metabolism in parasitic helminthes. It describes lipid composition, the process of the absorption of lipids, lipid syntheses, lipid catabolism, lipid utilization, and lipid excretion and presents histochemical studies on lipid distribution in parasitic helminthes.

The Pharmacology and Biochemistry of Parasitic Helminths
1964Publisher Summary This chapter reviews some of the recent studies concerning the carbohydrate metabolism and neuromuscular system of some parasitic helminths. The known effects of a relatively small number of chemical agents on these systems have also been discussed.

Replicating helminth parasites of man
Parasitology Today, 1986Most helminth parasites of man are unable to replicate within the human host. Thus, the worm burden of an infected person (on which the pathology largely depends - see Box 1) is a function of the number of infective forms to which the person is exposed. But for some species of helminths, the ability to replicate in man has a marked effect on the course

Energy Metabolisms of Parasitic Helminths: Adaptations to Parasitism
Annual Review of Physiology, 1981Many metazoans, and particularly the parasitic forms, have adapted well to their environments. This is particularly obvious in organisms that reside in anoxic surroundings, such as the large lumen-dwelling intestinal parasites. However, anaerobic energy metabolisms are not confined to parasites in microaerophilic environments.
