By Josh Lancette Lyme disease has been spreading across the United States over the past several decades, and a new study has confirmed that ticks carrying the disease are present in eastern national parks. According to the study published in the Journal of Medical Entomology, researchers from the Centers for Disease Control and Prevention (CDC) and […]

Scientists Have Sequenced the Genome of the Tick that Transmits Lyme Disease

An international team of scientists led by Purdue University has sequenced the genome of the tick that transmits Lyme disease, the most common vector-borne illness in North America. Ixodes scapularis, known as the blacklegged tick or the deer tick, is the first tick species to have its genome sequenced. The decade-long project, involving 93 authors […]

Ticks that Transmit Lyme Disease Reported in 48.6% of U.S. Counties

By Hannah Foster Lyme disease is a potentially debilitating disease caused by the bacterium Borrelia burgdorferi. The disease is spread to humans by two tick varieties: the blacklegged tick (Ixodes scapularis), which is responsible for most cases of Lyme disease in the United States, and the western blacklegged tick (Ixodes pacificus), the culprit for cases […]

A Tick that Feeds on Birds May Increase the Range of Lyme Disease

Ixodes-affinis

By Meredith Swett Walker If you have lived in the northeastern United States any time in the last 25 years or so, you have almost certainly heard of Lyme disease. You may have scrutinized odd-looking insect bites, wondering if they are developing the disease’s tell-tale “bulls-eye” rash. And you may have become skilled at distinguishing […]

Mice Aren’t Nice, They Help Transmit Lyme Disease

By Hannah Foster Upon hearing the words “Lyme disease,” most people think of two things: ticks and deer. Although these are certainly important aspects of the disease, ticks and deer are only two pieces of the puzzle. Lyme disease is actually extremely complicated, and its spread is affected by a wide range of organisms. Knowing […]

Ticks that Vector Lyme Disease Move West into North Dakota

According to the U.S. Centers for Disease Control, there are more than 300,000 cases of Lyme disease in the U.S. each year. Last year, most Lyme disease cases reported to the CDC were concentrated heavily in the Northeast and upper Midwest, with 96 percent of cases in 13 states. In fact, the disease gets its […]

Reduced Numbers of Deer can Lead to Fewer Lyme Disease Cases

Since white-tailed deer serve as the primary host for the adult blacklegged tick (Ixodes scapularis) — the vector for Lyme disease — scientists have wondered whether reducing the number of deer in a given area would also mean fewer cases of Lyme disease. Now, after a 13-year study was conducted, researchers in Connecticut have found […]

Ticks are Still Abundant, Despite Cold Weather

“Despite the long, cold winter, ticks are abundant in New York State and surrounding areas,” according to Paul Curtis, coordinator of Cornell University’s Wildlife Damage Management Program and associate professor of Natural Resources. “The persistent snow cover helped insulate overwintering ticks in the leaf litter.” While weather and other conditions may be factors, the size […]

White-footed Mice not Harmed by Ticks or Lyme Disease

The U.S. Centers for Disease Control estimates that each year there are about 300,000 cases of Lyme Disease, which is vectored by blacklegged ticks. These ticks are also commonly known as deer ticks, which may cause people to believe that ticks are infected with Lyme disease after biting deer. However, while it’s true that deer […]

CDC Estimates 300,000 Lyme Disease Cases in U.S. Each Year

Preliminary estimates released by the Centers for Disease Control and Prevention indicate that the number of Americans diagnosed with Lyme disease each year is around 300,000. The preliminary estimates were presented Sunday night in Boston at the 2013 International Conference on Lyme Borreliosis and Other Tick-Borne Diseases. This early estimate is based on findings from […]
