With the objective of studying the role of wild fauna in the epidemiology of fasciolosis disease, a definitive wild-host inventory was carried out in a french farm where infected domestic hosts (cows) cohabit with wild potential ones. Liver flukes, faecal eggs and antibodies were looked for in lagomorphs (Oryctolagus cuniculus) and rodents (Myocastor coypus, Ondatra zybethicus, Rattus norvegicu...

MF6p/FhHDM-1 is a small cationic heme-binding protein which is recognized by the monoclonal antibody (mAb) MF6, and abundantly present in parenchymal cells and secreted antigens of Fasciola hepatica. Orthologs of this protein (MF6p/HDMs) also exist in other causal agents of important foodborne trematodiasis, such as Clonorchis sinensis, Opisthorchis viverrini and Paragonimus westermani. Conside...

background : in this study, we used both its1 and its2 for molecular identification of fasciola species. methods : the region between 18s and 28s of ribosomal dna was used in pcr-rflp method for molecular identification of fasciola species. ninety trematodes of fasciola were collected during abattoir inspection from livers of naturally infected sheep and cattle from khorasan, east azerbaijan, a...

In many infection experiments attention has been focused mainly on the rate of the larval development of F. hepatica and the number of rediae and mature cercariae produced by infected L. truncatula (Kendall, 1949; Roberts, 1950; Boray, 1969). Very little consideration has been given to the actual numbers of cercariae which emerge from infected snails. Knowledge of the output of cercariae from i...

El estudio se llevó a cabo para establecer la prevalencia e identificar los factores de riesgo asociados con las infecciones por trematodes en ganado lechero tierras altas Boyacá, Colombia. Las muestras fecales recogidas 300 bovinos seleccionados al azar examinaron utilizando una técnica sedimentación simple el recuento diferencial huevos trematodes. En estudiado fueron encontrados tres grupos ...

background:  fascioliasis is considered as the most important helminthic infection of cattle and sheep. traditional approaches using morphological and biologic characters cannot cause a cer­tainty in the accurate and precise identification and intra-specific differences of fasciola spp. in this study, we identified fasciola species using its-1 marker and described genetic variation of each spec...

We have studied the influence of both levamisole (AL) and Freund's adjuvant (AF) on the immunisation of mice with the secretory antigens of adults of the liver fluke Fasciola hepatica Linnaeus, 1758. Total IgG antibodies were detected in all groups where the F. hepatica antigen was administered, been levels of IgG1 increased respect to IgG2a antibodies. During immunisation, IL-4 and IFN-γ were ...

Fasciolosis is a trematode zoonosis of interest in public health and cattle production. We report here the immunostimulatory effect of a 66 mer mucin-like peptide from Fasciola hepatica (Fhmuc), which synergizes with lipopolysaccharide (LPS) to promote dendritic cell (DC) maturation, endowing these cells with Th1-polarizing capacity. Exposure of DCs to Fhmuc in presence of LPS induced enhanced ...

Eggs of Fasciola hepatica were exposed for 10 days to extremely low frequency magnetic field (ELFMF) at the frequency of 50 Hz and density of 2 mT (rms). The results show an accelerated hatching of F. hepatica eggs in relation to control (non-exposed) group. The host snails, Lymnaea truncatula, were divided into three groups; those of groups I and II were infected with the miracidia of F. hepat...
