Researchers studying deer ticks in North Dakota have confirmed Lyme disease in one of the ticks captured during a research project that began last spring. According to Nate Russart, a University of North Dakota graduate student working on the tick study, Lyme disease was confirmed in a single adult deer tick captured in Steele County. Researchers sampled 92 deer ticks, mostly in eastern North Dakota, and none of the other ticks tested positive for the disease, Russart said.
Relatively common in Minnesota, which has more of the forested habitat deer ticks prefer, Lyme disease remains uncommon in North Dakota. But more cases have shown up in recent years.
According to the state’s Department of Health, North Dakota had 15 confirmed or suspected cases of Lyme disease in , along with 11 cases in , 12 cases in and seven cases in From to , North Dakota had no more than three cases, and there were no reports of Lyme disease in , and , the health department said.
Minnesota, by comparison, has had to more than 1, Lyme disease cases since , according to statistics from the state health department. Russart said he wasn’t surprised to find Lyme disease in one of the deer ticks. If anything, he said he would have expected more of the ticks to test positive.
Jennifer Cope, an epidemiologist for the state Health Department in Bismarck, said the confirmed presence of deer ticks is the most important finding in the study so far. Even though tests found only one tick with Lyme disease, she said the presence of the ticks in North Dakota means there’s potential for more cases of the disease.
The goal, she said, is to educate clinicians who might not routinely diagnose Lyme disease to be on the lookout. The state Health and Game and Fish departments helped fund the study, which also includes researchers from North Dakota State University. Russart said most of the deer ticks found were on the small mammals. Wood ticks are known to carry diseases such as Rocky Mountain spotted fever, but not Lyme disease.
Russart said he made two sweeps across the state collecting ticks, along with additional sampling closer to Grand Forks, and the deer ticks were most abundant in northeastern North Dakota.
Adult deer ticks are about half the size of a wood tick, and the nymph and larval stages are even smaller. Read Today’s Paper Saturday, October 8.

– Diseases that can be Transmitted by Ticks | Department of Health
In fact, the disease gets its name from the northeastern town of Lyme, Connecticut , where it was first discovered. A tick can transmit Powassan in as little as 15 minutes after biting a human. Crandall said he’d never seen anything like it at the park, either. Ticks can spread diseases when they are infected with certain types of bacteria, viruses, or parasites. Of the 13, ticks collected and sent to the state laboratory for disease testing, nearly half were contributed by a single interested individual — John Heiser of Grassy Butte. Several months later, I received notice that the tick had tested positive for Lyme disease. Little did he know he would be diagnosed with alpha-gal syndrome within weeks.
