The unpredictable epidemiology of Dictyocaulus viviparus lungworm infection of cattle
Together, helminth parasites are the most important animal health constraint to global ruminant livestock production. Better control of gastrointestinal and lungworm nematodes (and liver flukes) in Irish and UK cattle is a priority to meet the need for food security through efficient livestock production. Persistent acting macrocyclic lactone anthelmintics are convenient to use and highly effec...
متن کاملImmune Cell Responses to the Cattle Lungworm, Dictyocaulus viviparus
The cattle lungworm, Dictyocaulus viviparus, is a parasitic nematode, which can cause severe pulmonary disease. Repeated natural infections result in protective immunity, and a live attenuated vaccine exists. However, live vaccines have several disadvantages, and alternative control methods are needed. Awareness of increasing anthelmintic resistance makes parasite control with reduced reliance ...
متن کاملOversummer and Overwinter Survival of the Cattle Lungworm Dictyocaulus vivipams on Pasture in Louisiana (U.S.A.)1
Two experiments were carried out during summer and winter conditions to determine if Dictyocaulus vivipams infective larvae could survive on pasture during these seasons in Louisiana. Pairs of tracer calves were grazed in August and September on a pasture that was heavily contaminated in May and then left free of cattle during June-July. These tracers were not infected with D. vivipams, indicat...
متن کاملLungworm Infections in German Dairy Cattle Herds — Seroprevalence and GIS-Supported Risk Factor Analysis
In November 2008, a total of 19,910 bulk tank milk (BTM) samples were obtained from dairy farms from all over Germany, corresponding to about 20% of all German dairy herds, and analysed for antibodies against the bovine lungworm Dictyocaulus viviparus by use of the recombinant MSP-ELISA. A total number of 3,397 (17.1%; n = 19,910) BTM samples tested seropositive. The prevalences in individual G...
متن کاملPopulation genetics of the bovine/cattle lungworm (Dictyocaulus viviparus) based on mtDNA and AFLP marker techniques.
Mitochondrial DNA (mtDNA) sequence data and amplified fragment length polymorphism (AFLP) patterns were compared for the lungworm Dictyocaulus viviparus, a nematode parasite of cattle. Eight individual D. viviparus samples from each of 8 herds in Sweden and 1 laboratory isolate were analysed, with the aim of describing the diversity and genetic structure in populations using different genetic m...
