AgCenter scientists receive grant to study insect-borne deer, cattle diseases

AgCenter scientists receive grant to study insect-borne deer, cattle diseases Writer: Olivia McClure at 225-578-3262 or omcclure@agcenter.lsu.edu (08/16/17) BATON ROUGE, La. — LSU AgCenter scientists Lane Foil and Claudia Husseneder have been awarded a three-year, $490,000 grant to study two insect-borne diseases that affect deer and cattle. The U.S. Department of Agriculture National Institute of Food and Agriculture grant will fund the project, “A Prospective Study on Epizootic Hemorrhagic Disease Virus and Bluetongue Virus Transmission in Cervid and Cattle Populations.” The grant includes support from the National Science Foundation Established Program to Stimulate Competitive Research. Both viruses cause what commonly is referred to as hemorrhagic disease. The only insects known to transmit the diseases are biting midge species. Infected deer suffer hemorrhages in multiple organs and typically die. “Survivors develop immunity that lasts for several years depending upon subsequent exposure, and fawns of surviving does can receive protective antibodies in colostrum,” Foil said. Symptoms are less severe in cattle and include a crusty, peeling muzzle; sores and ulcers in the mouth; stiffness; lameness; and loss of appetite. Hemorrhagic disease-related deaths are not uncommon in wild deer, but usually the impact on populations is minimal, Foil said. However, widespread outbreaks — such as one in 2012 that claimed the lives of thousands of wild deer in states including Michigan, Missouri and Nebraska — sometimes happen. “The two viruses can cause devastating losses in captive deer herds in Louisiana and elsewhere as well,” he said. The AgCenter project will focus on identifying insects that carry the two viruses and studying how the viruses overwinter, or persist between active transmission seasons, in both animal tissue and insects. The scientists also will work to develop methods to identify immature midges and learn more about their developmental habits and food webs. “The ultimate goal is to generate knowledge that can lead to control methods to protect wild and captive ruminants,” Foil said. The majority of the field work will take place at the AgCenter Bob R. Jones-Idlewild Research Station, which has herds of cattle, wild and captive white-tailed deer, and red deer. A portion of the laboratory work will be conducted on the LSU campus in the Department of Entomology. The project is one of several initiatives of the Bob R. Jones Wildlife Research Institute. The institute is housed at the research station, which is located near Clinton.
