Flukes of ruminants are flatworm (trematodes) parasites living in the liver, fore stomachs or blood vessels, of which 40 different species may be present. Many other trematodes are parasites of fishes, poultry, carnivores and man. The liver fluke, Fasciola hepatica, was first described in France by Jean de Brie (1379), in his treatise on wool production and sheep management for the king Charles...

Parasitology textbooks have long reported that grapsid crabs in the genus Eriocheir, commonly known as mitten crabs, are important second intermediate hosts of the Oriental Lung Fluke, Paragonimtrs westermani, along with several other crab'and crayfish species in Asia (e.g., Hegner and others 1929; Chandler and Read 196 1 ; Muller 1975; Cheng 1986; Smyth 1994). Epidemiologic reviews have specif...

A retrospective study was carried out in year 2003, to show the prevalence of hydatid cysts, liver flukes and lung worm among slaughtered sheep, goats, calves, cattle and buffaloes in Kirkuk slaughter house. The number of ruminants slaughtered in Kirkuk abattoir was sheep (40233), goats (9223), calves (9577), cattle (2855) and buffaloes (50). It was found that the highest rate of hydatid cysts ...

Schistosomiasis is a waterborne, parasitic disease, found in much of the Third World. The World Health Organization (WHO) ranks schistosomiasis as one of the predominant tropical diseases in terms of socioeconomic and public health importance. I It is endemic in 74 countries and threatens as many as 600 million people as they perform daily activities related to water such as swimming, fishing, ...

Propulsive morphology and swimming performance were compared for the odontocete cetaceans Delphinapterus leucas, Orcinus orca, Pseudorca crassidens and Tursiops truncatus. Morphological differences were apparent among the whales. The general body contour and low-aspect-ratio caudal flukes of D. leucas indicated that this species was a low-performance swimmer compared with the other species. Pro...

Development of anthelmintic resistance and high cost of conventional anthelmintic drugs lead to the evaluation of medicinal plants which acts as an alternative source of anthelmintics. The present study has been undertaken to perform the evaluation of anthelmintic activity of Plumbago zeylanica belonging to family Plumbaginaceae. In the current study, experiments were conducted to evaluate the ...

background: to identify the fasciolid species by morphometric and molecular methods in zanjan, north­west of iran. methods : adult fasciola worms (n=584) were obtained from cattle and sheep in zanjan slaughterhouse in 2007. living flukes were washed, then worms' images were taken by 3ccd camera and finally apical zone of each worm was obtained. morphometric values such as body length, body widt...

Fasciolid flukes are among the largest and best known digenetic trematodes and have considerable historical and veterinary significance. Fasciola hepatica is commonly implicated in causing disease in humans. The origins, patterns of diversification, and biogeography of fasciolids are all poorly known. We have undertaken a molecular phylogenetic study using 28S, internal transcribed spacer 1 and...

The metacercariae of Centrocestus formosanus, a minute intestinal trematode of mammals and birds, were detected in the freshwater fish, Puntius brevis, from Vientiane Municipality, Lao PDR. The metacercariae were experimentally fed to mice, and adult flukes were recovered in their small intestines 7 days later. The adult flukes were morphologically characterized by having 32 (rarely 34) circumo...
