Welcome to EquiManagement’s podcast Disease Du Jour, where each podcast will delve into the research and current best practices for a variety of equine health problems with industry experts.
This episode’s guest is Dr. Craig Barnett, Director of the Equine Veterinary Professional Services segment at Merck Animal Health, to talk about the Merck Equine Respiratory Biosurveillance program and what it means to veterinarians, researchers and the horse industry. That program is celebrating its 11th anniversary in 2019 and earlier this year released 10 years of information gleaned from this program.
Barnett, who has been a horse owner and equine enthusiast his entire life, received his DVM from the University of Missouri. After graduation, he owned an equine/small animal veterinary practice in Spring Hill, Kansas. After a few years, he began his career as an equine technical services veterinarian in the pharmaceutical industry. Barnett is the Director of the Equine Veterinary Professional Services segment of Merck Animal Health, helping to guide practitioners and educate horse owners on ways to better care for horses.
Barnett is involved in a number of equine industry boards and committees, including the Kansas Horse Council Board of Directors, Equine Land Conservation Resource Board of Directors and American Horse Council Health & Regulatory Committee. Barnett has served on many AAEP committees, including as Chair of the AAEP Serology Task Force.
Barnett boards several retired horses on his ranch in Paola, Kansas, and he enjoys driving a team of horses and trail riding.
This podcast includes this quote from Dr. Nicola Pusterla, who leads the University of California, Davis, Equine Infectious Disease Research Laboratory, where program samples are submitted and analyzed:
“When we started this program, we had no idea how much we would gain over this period. The study has increased awareness of respiratory pathogens in the veterinary community, provided invaluable epidemiological information pertaining to common and less characterized respiratory pathogens, and provided sequencing of equine influenza virus isolates to monitor how the virus is changing in the field and to evaluate and improve the efficacy of vaccines. What Merck Animal Health has done is—and will remain—an unmatched service to the entire U.S. equine community.”
In this podcast we cover:
- the history of the Merck Animal Health Biosurveillance Program
- top clinical findings
- who is involved, from vets to researchers
- the fact that more than 8,200 samples have been taken to focus on these diseases
- equine herpesvirus-1 (EHV-1)
- equine herpesvirus-4 (EHV-4)
- equine influenza virus (EIV)
- Streptococcus equi subspecies equi
- equine rhinitis A virus (ERAV)
- equine rhinitis B virus (ERBV)
- results provided within 24 hours, which
- provides a timely and accurate diagnosis for their contact
- allows vets to prescribe optimal treatment for horses with infectious upper respiratory disease
- provides important information for making recommendations about vaccination, management and biosecurity during an infectious respiratory disease outbreak-including the potential need for quarantine
- lets researchers evaluate the efficacy of the current vaccination protocol
- 10 years of key findings were released earlier this year
- a bi-annual newsletter is sent as a value-added service to clinics enrolled in the program
