Dictyocaulus viviparus, the causative agent of bovine parasitic bronchitis, is an important parasite of dairy cattle. Infections can lead to substantial economic losses, due to mortality, reduced weight gain and milk production and treatment costs. There have been relatively few studies...

Background: Infections with the bovine lungworm Dictyocaulus viviparus might lead to reduced milk production and detrimental impacts on milk quality resulting in considerable economic losses in dairy farming. Methods: In the presented field study, 1988 faecal samples were collected from 1166 Black...

Infections with the bovine lungworm Dictyocaulus viviparus, the causative agent of parasitic bronchitis, are accompanied by substantial economic losses due to impacts on production, clinical respiratory disease or even death of diseased cattle. To detect lungworm antibodies in cattle, an...

Freshly calved dairy cows with cough and lacking milk production were investigated in October 2018 [Wales, UK]. In response to increased coughing, the cows had been treated with pour-on eprinomectin. Signs progressed to respiratory distress, subcutaneous emphysema and recumbency in one cow. The cow ...

Vaccination and anthelmintic (preventive) treatments for the control of the bovine lungworm Dictyocaulus viviparus have been available for some time. However, the number of outbreaks experienced has remained high, with clinical disease in adult cattle often causing particularly dramatic, milk...

To test the value of a recently developed bulk-tank milk (BTM) ELISA for diagnosing (sub)clinical Dictyocaulus viviparus infection in lactating dairy herds under field conditions, bulk milk samples were collected from farms with or without clinical symptoms suspected to be caused by lungworm...

Background: Clinical disease caused by the bovine lungworm (Dictyocaulus viviparus) causes significant welfare and economic problems for the livestock industry. Anecdotal reports suggest that the number of clinical cases has increased, particularly in Northern England and Scotland. However, these...

The lungworm Dictyocaulus viviparus can have a major impact on bovine health and productivity. Enzyme-Linked Immunosorbent Assays (ELISA), based on a recombinant Major Sperm Protein (MSP), have been developed to detect D. viviparus-specific antibodies in bulk tank milk (BTM). The objectives of this ...

Background: The lungworm Dictyocaulus viviparus, causing parasitic bronchitis in cattle, induces a temporary protective immunity that prevents clinical disease. A radiation-attenuated larvae based vaccine is commercially available in a few European countries, but has the disadvantages of a live...

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 lung-worm Dictyocaulus viviparus by use of the recombinant MSP-ELISA. A total...
