Abstract

IgG1 antibody responses to O. ostertagi 3rd-stage larvae (L3) and the 3rd party antigen, keyhole limpet haemocyanin (KLH), and faecal egg counts were determined in calves infected with a single dose of O. ostertagi and in uninfected, pair-fed calves. The infected and uninfected calves were given...

Abstract

Serum samples, collected monthly from January through December 1988 from 10 cows, their calves, and 10 yearling heifers, were used to determine total and Ostertagia-specific IgE levels. In addition, serum pepsinogen concentrations, faecal egg counts, and body weights were measured. The following...

Abstract

Four groups each of 6 calves were given one of two diets, and were either infected or not infected with 3000 O. ostertagi L3 on alternate days for 6 weeks. The diets were either high (H) or low (L) in protein/energy and were within the range of normal husbandry practice in the UK. Both IgG1 and IgG...

Abstract

The experiment reported comprised 3 groups of calves, (+P2), (-P2) and (-P1), which all started their first grazing season as parasite-free calves. The (+P2) and (-P2) groups grazed for 2 seasons. In the first season the (-P2)-group of calves was grazing a pasture with no detectable...

Abstract

The immune responses to bovine ostertagiasis and the role Ostertagia mediators play in these responses through their regulatory effects on host immune cells are described. The current understanding of O. ostertagi antigens is reviewed. A hypothesis is proposed for the mechanisms of acquired...

Abstract

Studies have shown that the number of gastrointestinal nematode eggs release per gram of faeces (EPG) of calves is strongly influenced by host genetics. The purpose of this study was to determine if host genetics also influenced immune recognition of parasite antigens in these same calves. Serum...

Abstract

A series of experiments was performed to determine whether immunoglobulin E (IgE) and Type I hypersensitivity reactions might be involved in the immune response of cattle to infection with Ostertagia ostertagi. The following observations were made. When calves were lightly infected, serum IgE...

Abstract

Changes in serum total and Ostertagia-specific IgE levels, and pepsinogen concentrations were evaluated in 28 Holstein calves naturally or experimentally infected with O. ostertagi. In addition, IgE and pepsinogen concentrations were determined in abomasal lymph. Results showed that lymph IgE...

Abstract

Antibodies against Ostertagia spp., Cooperia spp. and Dictyocaulus viviparus were assessed in serum and individual milk samples of cows and in bulk milk samples from the refrigerating tank. Titres in milk samples were related to serum titres, but also influenced by milk yield, lactation stage and...

Abstract

Serum anti-Ostertagia ostertagi and anti-Cooperia oncophora antibody responses were assessed in first season and second season calves grazing permanent paddocks. Calves without previous exposure to trichostrongyles were found to mount significant parasite-specific IgG1 antibody responses within two ...
