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 influence of prophylaxis on the immune response to gastrointestinal nematodes was evaluated in 3 groups of 10 first-season grazing calves. Group C functioned as untreated controls, whereas Group L received 2 treatments, one at turn-out and one 8 weeks later, with doramectin (200 µg/kg) and...

Abstract

This review briefly summarises different aspects (including development and measurement) and manifestations of protective immunity in cattle against gastrointestinal nematodes, especially Ostertagia ostertagi, and the factors that may interact with the development of this immunity. There follows a...

Abstract

The responses of peripheral blood and lymph node lymphocytes to O. ostertagi antigen extracts were determined in O. ostertagi-exposed and naive calves. The lymphocyte responses induced by O. ostertagi antigen extracts of the third (L3) and fourth (L4) larval stages, as well as adult worms, were...

Abstract

Larval migration inhibition (LMI) activity of abomasal mucus from calves naturally infected with gastrointestinal nematodes was studied in vitro. LMI activity was also assessed in serum from calves during both natural and artificial O. ostertagi infections to monitor the development of acquired...

Abstract

This review discusses the immune responses to gastrointestinal nematodes in cattle and the different immunological and parasitological parameters used to assess acquired immunity. Measuring acquired immunity to gastrointestinal nematodes in cattle (e.g. for the evaluation of candidate parasite...

Abstract

The contribution of different bovine cell subpopulations in the development of in vitro induced responses by O. ostertagi third larval antigen extract (L3) was investigated in bovine abomasal lymph node cell suspensions depleted of specific cell populations. The depleted cell suspensions were...

Abstract

Intramuscular immunization of calves with an excretory-secretory antigen fraction enriched for cysteine proteinase activity (ES-thiol) and QuilA as adjuvant induces a protective immune response against the abomasal nematode Ostertagia ostertagi. A study was conducted to confirm the protective...

Abstract

The protective capacity of an adult stage Ostertagia ostertagi globin antigen was tested in four vaccination experiments in cattle. In a preliminary experiment, calves were vaccinated three times intraperitoneally with 250 µg globin in Freund's adjuvant and challenged with a trickled infection of...
