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 Fasciola spp....

Reports of Calicophoron daubneyi infecting livestock in Europe have increased substantially over the past decade; however, there has not been an estimate of its farm level prevalence and associated risk factors in the UK. Here, the prevalence of C. daubneyi across 100 participating Welsh farms was recorded, with climate, environmental and management factors attained for each farm and used to cr...

A characterization of the humoral immune response of alpacas to Fasciola hepatica Fas1 and Fas2 antigens cysteine proteinases was performed over the course of 6 months of experimental infection. Six adult alpacas aged 1 to 2 years old received a single dose of 200 F. hepatica metacercariae, 2 non–infected alpacas were kept as control group. Peripheral eosinophilia in infected animals was greatl...

The geographical distribution and factors associated with bovine fasciolosis in the south of Espírito Santo were updated and the prevalences of this disease and of snails of the genus Lymnaea in the municipality of Jerônimo Monteiro were calculated. In the first stage, fecal samples were collected from 10% of the herds of 115 farms in 23 municipalities and interviews were conducted with owners....

OBJECTIVE Gastrointestinal parasitosis is a significant cause of morbidity and mortality. Definitive diagnosis is usually made by stool tests and/or serology but may require tissue evaluation. Although pathologists are usually familiar with common parasites, it is not well established whether the diagnosis could be suspected without seeing the "parasite" itself. MATERIAL AND METHOD Resection ...

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...

Fasciola hepatica is a helminth pathogen that drives Th2/Treg immune responses in its mammalian host. The parasite releases a large number of molecules that are critical to inducing this type of immune response. Here we have selected recombinant forms of two major F. hepatica secreted molecules, the protease cathepsin L (rFhCL1) and an antioxidant, sigma class glutathione transferase (rFhGST-si...

Alternatively activated macrophages (AAMphi) are primarily associated with the chronic stages of parasitic infections and the development of a polarized Th2 response. We have shown that Fasciola hepatica infection of BALB/c mice induces a polarized Th2 response during both the latent and chronic stage of disease. The activation status of macrophages was analyzed in this model of helminth infect...

BACKGROUND Fascioliasis is a chronic hepatic disease and may be resulted from mechanical/molecular parasite adhesion to host liver tissue. The aim of this study was to detect surface carbohydrate and lectin, carbohydrate-binding protein isolation that might be responsible of this molecular binding. METHODS The present experimental work was conducted in the Department of Medical Parasitology a...

INTRODUCTION Hepatic capillariosis, caused by Capillaria hepatica (Calodium hepaticum) (Bancroft, 1893), Travassos, 1915 (Nematoda, Trichinelloidea, Capillariidae), is a common zoonosis in rodents but is rare in humans. Seventy-two cases in humans have been reported worldwide since the first case was described by MACARTHUR in 192417,27. This study aimed to determine the prevalence of Capillaria...
