More Than Lyme: Study in Long Island Finds Multiple Agents of Tick-Borne Diseases

Andy · Sep 17, 2019

In a study published in mBio, a journal of the American Society for Microbiology, Jorge Benach and Rafal Tokarz, and their co-authors at Stony Brook University and Columbia University reported on the prevalence of multiple agents capable of causing human disease that are present in three species of ticks in Long Island.

The researchers studied the three primary human-biting tick species present on Long Island, left to right: Blacklegged tick (also known as the Deer tick), American Dog tick, Lone Star tick.

Tick-borne diseases have become a worldwide threat to public health. In the United States, cases more than doubled, from 22,000 in 2004 to more than 48,000 in 2016, according to the U.S. Centers for Disease Control. Tick-borne diseases range from subclinical to fatal infections with disproportionate incidence in children or the elderly. Moreover, some infections can also be transmitted by blood transfusions and cause severe disease in patients with underlying disorders. While public attention has focused on Lyme disease, in recent years, scientists have uncovered evidence that ticks can carry several different pathogens capable of several different tick-borne diseases, sometimes in a single tick.

In the new study, researchers collected ticks from multiple locations throughout Suffolk County in the central and eastern part of Long Island, where seven diseases caused by microbes transmitted by ticks are present. In total, they examined 1,633 individual ticks for 12 separate microbes. They found that more than half of the Ixodes (deer ticks) were infected with the Lyme disease agent, followed by infections with the agents of Babesiosis and Anaplasmosis. Importantly, nearly one-quarter of these ticks are infected with more than one agent, resulting in the possibility of simultaneous transmission from a single tick bite.

Are we to take it from this that R buchneri is confirmed as Burgdorfer's "East side agent", which appeared to him to be the same as "Swiss agent"?

It may be necessary to revisit responses given to reported enquiries on this subject to see whether they were entirely helpful.

It is to be hoped that similar investigations will be carried out in other tick populations where Lyme is prevalent, to see whether there is similar, or different, diversity.
