Longhorned tick found in Pa.
From staff reports
HARRISBURG — Pennsylvania’s first longhorned tick has turned up in Centre County’s Potter Township.
The identification was confirmed by the U.S. Department of Agriculture’s National Veterinary Services Laboratory.
The single longhorned tick was identified on an adult, male wild white-tailed deer that was euthanized on July 10 by Game Commission personnel because it was exhibiting signs consistent with chronic wasting disease.
Ticks were collected from the deer at the laboratory as part of the Game Commission’s active longhorn tick surveillance program. The suspected longhorn tick was sent to and first identified by the Southeastern Cooperative Wildlife Disease Study in Athens, Ga., and subsequently confirmed at the NVSL.
The longhorned tick, also known as the “cattle tick” or “bush tick,” is an invasive parasite native to Southeast Asia. It currently is not known when, where or how this tick was introduced into North America. However, it was first found and identified on a sheep in New Jersey in 2017. Since then, it has been identified in wild and domestic animals in other states.
The longhorned tick can negatively impact the health of humans and animals both directly and indirectly. Longhorned tick infestations can reach very high numbers on an animal host, which can result in disease and, in some cases, death.
The longhorned tick, in its native range, can carry many pathogens that may cause diseases such as babesiosis, anaplasmosis, theleriosis, ehrlichiosis and Powassan encephalitis in animals or humans. To date, none of these pathogens have been identified in longhorned ticks from North America.
“The preventive measures currently used for our native ticks are the best way to protect yourself and animals from the longhorned tick,” Brown said. “They include frequent tick checks, prompt and proper removal of any attached ticks, avoiding or removing the high grasses or brush where ticks concentrate, and tick treatments.”
Concerns regarding ticks on humans or domestic animals should be addressed through consultation with a physician or veterinarian.
Additional information on the longhorned tick can be found on fact sheets provided by the U.S. Department of Agriculture and Penn State. Longhorned tick questions concerning wildlife should be directed to the Game Commission; humans, Pennsylvania Department of Health; and domestic/agricultural animals, Pennsylvania Department of Agriculture.
