Abstract

Four heifers (6 months old), that were infected orally with 400 or 800 F. hepatica metacercariae, showed an increase in anti-fluke antibody titre by ELISA 2 weeks after infection. Eggs were first detected in the faeces 10 weeks after infection. Egg output increased steadily over the next 8 weeks...

Abstract

Research was being devoted to a rapid immunodiagnostic test for field use, comparison of the immunomodulatory activity of juvenile and adult flukes in susceptible and resistant hosts, and identification of molecular mechanisms permitting the establishment of fluke infestation.

Abstract

To standardize the test, 80 serum samples from adult cattle were used. 40 were from the State of Sonora (a fasciolosis-free area) and 40 from the State of Hidalgo (endemic for fasciolosis). The test showed a 97.5% sensitivity and 80.0% specificity. The cut-off value was 7 mm. In another study, 15...

Abstract

The efficacy of a serological test (ELISA with excretory-secretory products of Fasciola hepatica as an antigen) for the diagnosis of bovine fasciolosis was assessed under field conditions using pools of sera from 170 herds. Blood samples were collected from 6 to 10 heifers and from 5 to 10 adults...

Abstract

A study compared the sensitivity, specificity and usefulness of the diffusion in gel (DIG)-ELISA, DOT-ELISA and indirect ELISA tests for determining the seroprevalence of fasciolosis in cattle under tropical conditions in Mexico. To standardize the tests, positive and negative sera to Fasciola...

Abstract

The evolution of parasite virulence can be studied in cross-transfer experiments, combining hosts and parasites from different localities, and comparing the outcome of established (sympatric) and novel (allopatric) combinations of hosts and parasites. The compatibility of Fasciola hepatica with...

Abstract

Serum ELISA is the most sensitive and reliable test in individual animals. In dairy herds ELISA can be used on pooled milk for herd diagnosis. Interpretation and practical uses of the test are discussed.
