Abstract

The aim of this study was to optimize an in-house ELISA based on a recombinant version of the major sperm protein (MSP) of Dictyocaulus viviparus for routine diagnosis of lungworm infection in cattle. A recombinant MSP (rMSP) was cloned into pGEX-6P-1 vector and expressed as a...

Abstract

A recent increase in husk (lungworm disease) caused by Dictyocaulus viviparus in cattle in the UK is reported and the control of this disease and parasitic gastroenteritis (PGE, mainly caused by Ostertagia ostertagi) is discussed. Farmers should collaborate with veterinarians to devise annual...

Abstract

The epidemiology of gastrointestinal nematode infections and their effects on cattle are reviewed. The 3 most important nematodes which infect cattle in New Zealand are Ostertagia ostertagi, Trichostrongylus axei and Cooperia oncophora. The general principles of parasite control are considered, and ...

Abstract

Three experiments were carried out on calves experimentally or naturally infected with gastrointestinal nematodes and lungworms and treated with a "pour-on" formulation of levamisole (Niratil ND, Gifavet Virbac) at 10 mg/kg bodyweight. The efficacy of this formulation as estimated by worm or...

Abstract

Three-month-old calves were infected 3 times weekly during a 5-week period with C. oncophora, O. ostertagi or a combination of these 2 species. For each type of infection 2 dose levels were applied. In addition one group of calves was kept uninfected. After removal of the primary infection by...

Abstract

Twenty crossbred beef heifer calves were used for an efficacy evaluation of 0.5% moxidectin pour-on against gastrointestinal nematodes and Dictyocaulus viviparus. The latter parasite and Bunostomum phlebotomum were the target species. The calves were exposed to natural infection on pasture from...

Abstract

Interactions between gastrointestinal worms (Ostertagia ostertagi, Cooperia oncophora) and lungworms (Dictyocaulus viviparus) in calves were studied by assessing the effect of primary infections with either group of worms on the development of homologous or heterologous challenge infections....

Abstract

Efficacy of abamectin against gastrointestinal tract nematodes and lungworms of cattle was determined in 4 experiments. The first 2 experiments were controlled trials in which efficacy was determined at P.M. examination in calves with either experimentally induced (n = 14) or naturally acquired (n...
