Abstract

The influence of different levels of infection with O. ostertagi on the development of a protective immune response in calves was investigated. Four groups of calves were infected with either 5000 (Group A), 10 000 (Group B), 20 000 (Group C) or 40 000 (Group D) infective larvae (O. ostertagi L3)...

Abstract

Antigenic differences between the developmental stages of O. ostertagi were studied by SDS-PAGE and Western blotting. Gel electrophoresis showed a complex protein pattern different for every stage with the O. ostertagi fourth stage larvae (L4) showing an intermediate protein pattern between the...

Abstract

The present study reports on the development of a copro-antigen capture ELISA for detecting Ostertagia ostertagi infections in cattle. The ELISA was based on polyclonal rabbit antibodies, which recognize O. ostertagi excretory/secretory (ES) antigens. ES antigens are released by the metabolic...

Abstract

Cysteine proteinase enriched fractions obtained by thiol-sepharose chromatography of O. ostertagi membrane-bound protein extract (S3-thiol) or total adult excretory-secretory (ES-thiol) products were tested in a vaccination experiment to evaluate their protective efficacy against O. ostertagi in ...

Abstract

In temperate climate regions, gastrointestinal nematodes are still widespread in adult dairy cows, but until now there exists no reliable diagnostic tool that can identify herds where the infection interferes with productivity. The objective of this study was to investigate the relationships...

Abstract

A cross-sectional questionnaire survey was performed on dairy herds in Flanders (Belgium) to detect management factors that are associated with an increased gastrointestinal parasite infection level of adult dairy cows. At the end of the grazing season, information concerning general herd factors,...

Abstract

Our primary objective was to determine the relationships between Fasciola-specific antibody levels in bulk-tank milk and measures of productivity to estimate economic losses that are associated with Fasciola infections. A bulk-tank milk sample was collected in March 2004 from 1105 dairy herds in...

Abstract

The objectives of this study were (1) to determine the effect of a treatment with eprinomectin in autumn of pastured dairy herds on the anti-Ostertagia ostertagi bulk-tank milk antibody level, (2) to determine the overall effect of this treatment on three milk-production parameters (milk yield,...

Abstract

The Ostertagia-specific antibody levels in milk were monitored in 2 dairy herds to investigate seasonal variations and the relationship between individual and bulk tank milk antibody levels. Bulk tank and individual milk samples from all lactating animals were collected over a 1-year period at...

Abstract

Measurement of antibodies to Ostertagia ostertagi in bulk tank milk (BTM) has value as a diagnostic indicator for potential production losses and anthelmintic treatment responses in dairy herds. Most of the recent data on O. ostertagi antibodies in milk have been generated in Belgium and Canada;...
