Fasciola hepatica is a parasite that affects the hepatic ducts of several species of domestic and wild vertebrates, causing huge economic losses to livestock rearing worldwide. Reports on occurrences of F. hepatica in capybaras are an important epidemiological aspect of this disease, since these rodents can be a source of contamination for other animals and humans. In the present study, conduct...

AIM Fascioliasis is one of the most zoonotic diseases with global extension. As the epidemiological distribution of Fasciola may lead to various genetic patterns of the parasite, the aim of this study is to identify Fasciola hepatica based on spermatogenesis, and phylogenetic analysis using mitochondrial (nicotiamide adenine dinucleotide dehydrogenase subunit I [ND1] and cytochrome oxidase subu...

Experimental infections of Galba truncatula (two populations) with Fasciola hepatica or Paramphistomum daubneyi were carried out to study the effect of water temperature changes (3 h at a mean of 12 °C every week) on cercarial shedding during the patent period. The results were compared with those of control snails infected according to the same protocol and always maintained at 20 °C. Compared...

Fascioliasis is primarily an infection of livestock such as cattle and sheep, caused by the flat, brown liver fluke Fasciola hepatica. Humans are accidental hosts. The diagnosis of infection depends on suspicion. Radiologic findings are specific. Usually, Computed Tomography (CT) and other imaging studies show hypodense migratory lesions of the liver. The development of a chronic liver abscess ...

understanding genetic structure and status of genetic variation of fasciola hepatica isolates from different hosts, has important implications on epidemiology and effective control of fasciolosis. random amplified polymorphic dna (rapd-pcr) was used to study the genetic variation of f. hepatica in sheep and cattle. dna was extracted from adult helminthes removed from livers of each infected ani...

BACKGROUND The trematodes of the genus Fasciola (the liver flukes) are among the well-known instances of food-borne parasites worldwide. Differentiation of Fasciola species is important because of their different transmission and epidemiological characteristics. The current study was undertaken to discriminate Fasciola species in the domestic ruminants of Urmia city, Iran. METHODS Adult fluke...

background: the aim of this study was to compare superoxide dismutase (sod) activity in fasciola hepatica and fasciola gigantica parasites. materials: f. gigantica and f. hepatica helminths were collected from abattoir and cultured in buffer media for 4 h at 37 °c. excretory-secretory (es) products were collected, centrifuged and stored at - 20 ◦ c. e-s protein concentration was measured by bra...

excretory-secretory products (esp) play an important role in the host biochemical defense by means of activities of detoxifying and antioxidant enzymes. the aim of this study was to evaluate praziquantel (pzq) effects by detection of glutathione s- transferase (gst) and superoxide dismutase (sod) enzymes activities in esp samples of fasciola spp. fasciola gigantica and fasciola hepatica adult p...

BACKGROUND The purpose of this comparative study was to detect superoxide dismutase (SOD) activities in Fasciola hepatica, F. gigantica parasites, infected and healthy liver tissues in order to determine of species effects and liver infection on SODs activity level. METHODS Fasciola spp. parasites and sheep liver tissues (healthy and infected liver tissues), 10 samples for each, were collecte...

A wild population of the lymnaeid snail Pseudosuccinea columella infected by larval stages of Fasciola hepatica was discovered in the Pinar del Río Province, Cuba. One of 100 snails was infected in a rice culture field. This is the first time this species has been found acting as intermediate host of F. hepatica under natural conditions, not only for Cuba but also for the Caribbean area.
