Abstract

Fasciolosis, caused by the liver fluke Fasciola hepatica, is one of the most important parasitoses in cattle farming worldwide. In dairy cows, the trematode leads to economic losses due to decreased milk yield, a negative impact on reproduction parameters, and liver condemnations. In the present study, the seasonal patterns of F. hepatica antibodies in bulk-tank milk from dairy herds located in East Frisia, a region of the federal state Lower Saxony in the north of Germany, were investigated. This region was chosen since it is known as a high risk area for fluke infections due to its coastal location at the North Sea with the consequence of rather moist pastures. Between 669 and 868 bulk-tank milk samples were collected in January, September and November 2008 and 2010, respectively, and analysed for antibodies against F. hepatica with an in-house ELISA based on excretory-secretory antigens of the liver fluke. The overall East Frisian prevalence was 49.1%, 57.1% and 53.9% in January, September and November 2008 and 45.1%, 49.5% and 48.4% in 2010. From a number of 606 farms, which were sampled in all six investigated months, 34.5% of the farms continued to remain positive, whereas 30.9% continued to remain negative. A percentage ...Continue Reading

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
