the laboratory infection of lymnaea gedrosiana with 2,5 and 10 miracidia of fasciola gigantica resulted in infection rates of 20%, 40% and 69%, respectively, with a prepatent period of 66-88 days. there was a significant difference in infection rate between the snails infected with 2 and those with 10 miracidia (p<0.05). at 92 days post- infection there was 25% to 33.3% of live snails still har...

background: heavy metals tend to bioaccumulate in living organisms, and their accumulation has been a major concern. as mammals are known to excrete heavy metals via their bile, it seems to be very promising to analyse metal burdens of par-asites that infect the biliary tree such as liver flukes of the genus fasciola . the pre-sent study was carried out to evaluate f. hepatica and f. gigantica ...

background: the study was targeted to report the appearance of coproantigens in feces and circulating antibodies in the serum of fasciola gigantica  experimentally infected rabbits. methods: copro hyper immune serum (his) and excretory-secretory hyper immune serum (es his) antigens were used in a sandwich elisa for the detection of f. gigantica antigens in feces of 12 rabbits experimentally inf...

18 The success of helminth parasites is partly related to their ability to modulate host immune 19 responses towards an anti-inflammatory/regulatory phenotype. This ability resides with the 20 molecules contained in the secretome of various helminths that have been shown to interact with 21 host immune cells and influence their function. Consequently, there exists a unique opportunity 22 to exp...

The current study aimed to find out the morphometric and genotypic divergences of the flukes isolated from different hosts in a newly emerging focus of human fascioliasis in Iran. Adult Fasciola spp. were collected from 34 cattle, 13 sheep, and 11 goats from Kohgiluyeh and Boyer-Ahmad province, southwest of Iran. Genomic DNA was extracted from the flukes and PCR-RFLP was used to characterize th...

background: aspartate transaminase (ast) is an important enzyme in parasite and liver tissue. the purpose of this investigation is to evaluate triclabendazole (tcbz) effect on ast activity of fasciola gigantica parasite. to compare of enzyme level of parasite and its host tissue, enzyme activity of f. gigantica parasite and liver tissues were also determined. method: the livers were collected f...

Genotypes from 10 polymorphic DNA microsatellite loci were used to make assessments of population structure, measurements of gene flow, and attempts to genetically segregate polymorphic host fish-attracting mantle displays for the wavy-rayed lampmussel, Lampsilis fasciola Rafinesque, 1820 — an endangered species in Canada. Specimens were collected from seven localities — six in the Great Lakes ...

Background The liver fluke Fasciola hepatica is one of the most important parasites affecting animal health all over the world, causing the so called liver fluke disease (fascioliosis). Although infections of humans are rather rare in most western countries, several million people worldwide are infected by this trematode. Beside its threat to humans the infection of animal stock leads to large ...
