Experts Discuss Lone Star Tick Population, Associated Disease

Veterinary conference session sponsored by Boehringer Ingelheim looks at the quick spread and impact of the parasite

ORLANDO, FL Feb. 6 – Three leading experts in human allergy, parasitology and entomology brought new perspectives on the Lone Star tick to members of the veterinary field today, with a panel sponsored by Boehringer Ingelheim at the North American Veterinary Community’s Veterinary Meeting and Expo in Orlando, Fla.

Onyinye Iweala, MD, Ph.D., allergist and immunologist at the University of North Carolina-Chapel Hill; Brian Herrin, DVM, Ph.D., DACVM, assistant professor at Kansas State University College of Veterinary Medicine; and Thomas Mather, Ph.D., professor of entomology and director of the TickEncounter Resource Center at the University of Rhode Island, presented a review of the diseases transmitted by the Lone Star tick and its appearance in different parts of the U.S.

“National news coverage has already underscored the presence of the Lone Star tick in areas of the U.S. and Canada,” said Zach Mills, DVM, executive director, U.S. Pet Vet Veterinary Professional Services at Boehringer Ingelheim. “This panel offered a timely discussion for veterinarians on the wide range of diseases this parasite can transmit, including a red meat allergy in humans.”

Three perspectives on the Lone Star tick Herrin led off the session with an overview of the diseases that can be transmitted by the Lone Star tick emphasizing that, as the Lone Star tick expands into new territories across the country, more pet owners and their animals may be exposed to tick-borne illness.

“Ticks are more than just a hygiene problem,” said Herrin, emphasizing that tick-borne diseases are a year-round danger. “People always ask me if ticks are going to be bad this year. And I say, ‘ticks are bad every year.’”

Medical professionals now know that bites from these ticks can trigger an allergy to red meat in humans. Iweala is one of the experts researching the connection between the Lone Star tick and the alpha-gal allergy first described in 2011. “Alpha-gal allergy challenges the current paradigm for food allergy,” Iweala said. She contrasted alpha-gal allergy with conventional food allergies, highlighting the unusual association of this food allergy with parasites like the Lone Star Tick and the significant delay in symptom development after eating mammalian meat.

Mather, often referred to as the “TickGuy,” wrapped up the discussion with a presentation of “Five Things Every Veterinarian Should Know About Lone Star Ticks. “Veterinarians need to keep in mind that Lone Star Ticks move quickly, they are commonly misidentified, their range is expanding, they do not transmit Lyme disease and their larvae are incredibly small,” Mather said.

BI will sponsor another panel discussion on the Lone Star Tick on March 6, 2018 during the Western Veterinary Conference in Las Vegas.

About the Lone Star Tick

An aggressive biter even among tick species, the adult Lone Star tick feeds on its host for seven to 10 days.1  According to the Centers for Disease Control and Prevention, it is currently found in at least 30 states.2  The tick is responsible for the transmission of serious zoonotic diseases including ehrlichiosis, Rocky Mountain spotted fever and tularemia. 1,2
