Schistosomes are blood flukes that parasitize the venous system of a wide range of animals including birds, cattle and primates. There are seven human pathogenic species of which the, most prevalent are S. hematobium, found mainly in Africa, S. mansoni found in Latin America as well as Africa, and S. japonicum, endemic in China and the Far East. According to WHO estimates, some 700 million inha...

The authors present an introductory overview of the principal groups of ectoparasites (flukes, leeches, crustaceans, insects, arachnids, lampreys and vampire bats) associated with domestic animals. Currently-accepted higher-level classifications are outlined for these parasites. Almost all significant ectoparasites of domestic animals are invertebrates, the majority being arthropods (crustacean...

infected by ingesting unwashed vegetables contaminated by animal feces containing strongyloid larvae. Larvae mature into adults in the intestines. Sporadic cases of this infection in humans have been reported in many countries (7). In France, several autochthonous cases were suspected, but because of their rarity and diffi culty in identifi cation, they are not commonly reported (8). Eggs of Tr...

<i>Fascioliasis hepatica</i> is a rare parasitic infection affecting the hepatobiliary system. On imaging examination, it presents as multiple hepatic abscesses and bile duct dilatation. Extrahepatic fascioliasis of gastrointestinal tract condition, resulting from duodenal migration fasciola flukes. The current case showed both colonic masses, mimicking colon cancer with metastasis....

Hatchery-reared fish show high mortalities after release to the wild environment. Explanations for this include potentially predetermined genetics, behavioral, and physiological acclimation to fish farm environments, and increased vulnerability to predation and parasitism in the wild. We studied vulnerability to Diplostomum spp. parasites (load of eye flukes in the lenses), immune defense (rela...
