A cDNA containing a 813 bp open reading frame encoding vitelline protein BI (FgVPBI) of Fasciola gigantica was cloned. FgVPBI has 96% sequence identity with VPBI of Fasciola hepatica and 84% identity with VPBII F. hepatica. It is far less similar to eggshell precursor proteins of other trematode species, for example, 29% identity with C. sinensis. Northern blot hybridization of total RNA from a...

background: fasciolosis, caused by the liver flukes of the genus fasciola , is one of the most prevalent diseases of domestic livestock and human throughout the world, imposing considerable economic losses. the present study was aimed to assess the effects of different ph values on hatching rate of fasciola miracidia . methods: the flukes were isolated from the infected livers of the slaughtere...

Experimental infections of six riverbank populations of Galba truncatula with Fasciola hepatica were carried out to determine if the poor susceptibility of these populations to this digenean might be due to the scarcity or the absence of natural encounters between these snails and the parasite. The first three populations originated from banks frequented by cattle in the past (riverbank group) ...

background: fasciola species are parasitic trematode with world wide distribution that infects wild and domesticated herbivores, particularly ruminants. the aim of the present study was to investigate the intra species variations of f. gigantica, from goats and buffalos isolates in two common geographic climates of iran. methods: fasciola species were collected from goat, buffalo, sheep, and ca...

background: fascioliasis caused by fasciola hepatica and f. gigantica is a foodborne and waterborne zoonotic disease with a worldwide distribution. the illness occurs in regions with intensive sheep or cattle production. in some parts of iran the incidence of human infection has increased over the past decades. since chaharmahal and bakhtiyari province has been known as a main pole of tradition...

Fascioliasis is a zoonotic infection caused by Fasciola hepatica or Fasciola gigantica. We report an 87-year-old Korean male patient with postprandial abdominal pain and discomfort due to F. hepatica infection who was diagnosed and managed by endoscopic retrograde cholangiopancreatography (ERCP) with extraction of 2 worms. At his first visit to the hospital, a gallbladder stone was suspected. C...

abstract background: we aimed to describe morphological and morphometrical characteristics of fasciola spp. in livestock from ardabil province, northwest iran. methods: forty adult flukes were collected from different definitive hosts (cattle and sheep). previously specimens were identified as f. hepatica or f. gigantica based on pcr-rflp of the its-1 region with rsai enzyme.  we identified fas...

Dynamics of serum liver enzymes in rabbits experimentally infected with metacercariae of Fasciola sp. (intermediate form between Fasciola hepatica and F. gigantica) were monitored. Gradual increase of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were observed from 3 weeks post-inoculation (WPI) and peaked at 6 WPI, which corresponded well to the period of migration ...

The levels of superoxide (O(-)2) and nitric oxide (NO) production by monocytes have been measured in 15 patients with S. mansoni, 15 patients with Fasciola and six patients with combined infection as well as in control group (15). The levels of both radicals were significantly higher in all patient groups than in the control group, indicating that these radicals may have a role in the immunity ...
