Liver flukes in Missouri: distribution, impact on cattle, control and treatment
"There are two types of liver flukes found in the United States that affect cattle. One is Fasciola hepatica, otherwise known as the common liver fluke. It is predominately located in Gulf Coast states and the Pacific Northwest and can have significant impact on bovine health and production. It is also a common cause of liver condemnations at slaughter. The second fluke is Fascioloides magna, also known as the deer fluke or the giant liver fluke. It is found in certain areas of the Gulf Coast, southern Atlantic seaboard, the Rocky Mountain trench, Pacific Northwest and is widespread throughout the Upper Great Lakes. It has also been found in Missouri, which has raised questions and concerns about this parasite. The purpose of this article is to describe the distribution of F. magna in the state, as well as the impact it has on cattle and strategies for control and treatment."--Page 1.
