The latest At The Meeting (ATM) with the Morrison Group audio program provides an update on developments in porcine epidemic diarrhea virus (PEDv) cases reported this spring, effective control steps and immunology in the last year. The ATM program on PEDv features disease, research and practical swine health information from leading veterinary experts that swine veterinarians and producers can use to make informed decisions for their farms.
In part one of the three-part audio program, Dr. Morrison talks with Gordon Spronk, DVM, Pipestone Veterinary Clinic, and Tom Wetzell, DVM, Boehringer Ingelheim Vetmedica, Inc. (BIVI), about ongoing swine health monitoring and case reporting programs in place for PEDv. This segment also provides insights that can be gained by looking at recent and historical PEDv case data and the impact the disease has had on production.
In the second segment, Jeremy Pittman, DVM, MSDABVP, Murphy Brown, joins the group to discuss the recent rebreaks of PEDv. He says most of the breaks are likely due to virus circulating in grow-finish barns, resulting in less mortality than initial outbreaks from 2013-14.
In the third segment, the panel of swine veterinarians, including Linda Saif, PhD, The Ohio State University, discuss what’s been learned regarding potential for protective immunity to be transferred from sow to pig, type of immunity provided and insights into the pig’s immune response to PEDv exposure. The group also discusses duration of immunity, types of vaccines and different administration routes that might be more effective in immunizing sows and pigs against PEDv.
