A species of helminth commonly called the sheep liver fluke. It occurs in the biliary passages, liver, and gallbladder during various stages of development. Snails and aquatic vegetation are the intermediate hosts. Occasionally seen in man, it is most common in sheep and cattle.

Liver disease caused by infections with parasitic flukes of the genus FASCIOLA, such as FASCIOLA HEPATICA.

A genus of trematode liver flukes of the family Fasciolidae. Two species of this genus are F. hepatica and F. gigantica. The parasites are found in the liver and gallbladder and associated ducts in mammals and occasionally man. F. gigantica occurs rarely in man.

Immunoglobulins produced in a response to HELMINTH ANTIGENS.

Any part or derivative of a helminth that elicits an immune reaction. The most commonly seen helminth antigens are those of the schistosomes.

A genus of dextrally coiled freshwater snails that includes some species of importance as intermediate hosts of parasitic flukes.

Agents used to treat cestode, trematode, or other flatworm infestations in man or animals.

Proteins found in any species of helminth.

A family of flukes of the class Trematoda found in the intestinal tract and liver of animals and man. Some of the genera are Homalagaster, Gastrodiscus, Paramphistomum, Watsonius, Nilocotyle, Gigantocotyle, Gastrothylax, Macropotrema, Ceylonocotyle, Zygocotyle, Cotylophoron, and Calicophoron.

A genus of trichuroid nematodes parasitic in the liver and intestines of many mammals and birds. Two species, C. hepatica and C. philippinensis, produce often fatal infections in man.

Infections with nematodes of the order ENOPLIDA.

A genus of intestinal flukes of the family Echinostomatidae which consists of many species. They occur in man and other vertebrates. The intermediate hosts are frequently mollusks.

Infection by flukes of the genus Echinostoma.

A ubiquitously-expressed cysteine protease that plays an enzymatic role in POST-TRANSLATIONAL PROTEIN PROCESSING of proteins within SECRETORY GRANULES.

A genus of trematode liver flukes of the family Dicrocoeliidae which includes the species dendriticum and hospes. It occurs in the biliary passages or liver of many vertebrates including man. The intermediate hosts are mainly mollusks but occasionally ants.

Halogenated anti-infective agent that is used against trematode and cestode infestations.

Marine, freshwater, or terrestrial mollusks of the class Gastropoda. Most have an enclosing spiral shell, and several genera harbor parasites pathogenic to man.

Compounds with two peroxide groups, that is, two pairs of adjacent OXYGEN atoms. They may have activity against PLASMODIUM similar to the ARTEMISININS.

Diseases of domestic and mountain sheep of the genus Ovis.

A plant genus of the family BRASSICACEAE. Nasturtium is also used as a common name for TROPAEOLUM. The common name of watercress is also used for RORIPPA & TROPAEOLUM. This is the most popular of the edible cresses, is a hardy creeping perennial plant, native to Europe but extensively naturalized elsewhere in moist places.

Creating a representation of areas of the earth or other celestial bodies, for the purpose of visualizing spatial distributions of various information.

Deoxyribonucleic acid that makes up the genetic material of helminths.

A group of lysosomal proteinases or endopeptidases found in aqueous extracts of a variety of animal tissues. They function optimally within an acidic pH range. The cathepsins occur as a variety of enzyme subtypes including SERINE PROTEASES; ASPARTIC PROTEINASES; and CYSTEINE PROTEASES.

Determination of parasite eggs in feces.

Compounds with a BENZENE fused to IMIDAZOLES.

Agents destructive to snails and other mollusks.

Infections with true tapeworms of the helminth subclass CESTODA.

A group of four homologous sphingolipid activator proteins that are formed from proteolytic cleavage of a common protein precursor molecule referred to as prosaposin.

Class of parasitic flukes consisting of three subclasses, Monogenea, Aspidogastrea, and Digenea. The digenetic trematodes are the only ones found in man. They are endoparasites and require two hosts to complete their life cycle.

A tricyclo bridged hydrocarbon.

An island in the Greater Antilles in the West Indies, south of Florida. With the adjacent islands it forms the Republic of Cuba. Its capital is Havana. It was discovered by Columbus on his first voyage in 1492 and conquered by Spain in 1511. It has a varied history under Spain, Great Britain, and the United States but has been independent since 1902. The name Cuba is said to be an Indian name of unknown origin but the language that gave the name is extinct, so the etymology is a conjecture. (From Webster's New Geographical Dictionary, 1988, p302 & Room, Brewer's Dictionary of Names, 1992, p132)

The relationship between an invertebrate and another organism (the host), one of which lives at the expense of the other. Traditionally excluded from definition of parasites are pathogenic BACTERIA; FUNGI; VIRUSES; and PLANTS; though they may live parasitically.

A species of trematode flukes of the family Opisthorchidae. Many authorities consider this genus belonging to Opisthorchis. It is common in China and other Asiatic countries. Snails and fish are the intermediate hosts.
