New Orleans, La. — From presentations on heartworm prevalence and pathology to sharing the latest research on heartworm diagnostics, prevention and treatment protocols, the 2019 American Heartworm Society (AHS) Triennial Symposium covered an unprecedented range of topics in its mission to better understand heartworm disease and reduce its impact. The conference, which featured 62 speakers and poster presenters, was held September 8–11, 2019, and was attended by an estimated 400 scientists, veterinarians, veterinary students, veterinary technicians and industry representatives from across the U.S. and at least 12 other countries.

“Heartworm disease remains one of the most challenging diseases faced by the veterinary profession,” stated Dr. Marisa Ames, co-chair of the 16th Triennial Heartworm Symposium program. “Whereas heartworm disease was once considered a problem confined to areas such as the Southeastern U.S. and Mississippi Delta, it is now recognized as a nationwide problem in the U.S., as well as a growing threat in many other parts of the world. This elevates the importance of understanding of heartworm disease and discovering new strategies for prevention, diagnosis and treatment.”

“Scientists are approaching the prevention and management of heartworm disease from many angles,” said incoming AHS president Dr. Chris Duke, adding that the AHS will be sharing information from the symposium via its website, its publications and its social channels, including FacebookTwitter and YouTube. A proceedings will be published at a later date in the journal Veterinary Parasitology.

Highlights of the three-and-a-half-day conference included:

  • The role of climate, microclimates severe weather events, animal transport, mosquito feeding habits and other factors in heartworm transmission
  • New research on products to prevent heartworm in dogs and cats
  • Discussion of the critical role of the immune response in heartworm prevention
  • New studies and insights on heartworm antigen and microfilaria tests, as well as strategies clearing antigen/antibody immune complexes
  • New insights on heartworm treatment, including a study on doxycycline vs. minocycline and additional strategies for managing dogs with severe disease
  • Practical insights on compliance for canine and feline heartworm prevention
