Different species of tick hosts tend to have different probabilities of transmitting an infection to a feeding tick. In eastern and central North America, the host most likely to transmit an infection to a feeding tick is the white-footed mouse (Peromyscus leucopus), which infects between 40% and 90% of feeding larvae.
Acorn production catalyzes chain reactions in a complex web of species interactions in oak forests that can influence forest health, via Gypsy Moth outbreaks, human health, via Lyme disease risk, and biodiversity via songbird nesting success. What are these and other acorn connections?
In areas where Lyme disease is endemic, it is desirable to control populations of native ticks, which transmit several pathogens to humans causing Lyme and other diseases.
To find out how to steer clear of Lyme disease during "picnic season" - a time when people are more likely to pick up ticks - the National Science Foundation spoke with NSF-funded disease ecologist Rick Ostfeld of the Cary Institute.
With the snow melted and the weather warming, folks are finally making their way outdoors, where, if you live anywhere in the Hudson Valley, the black-footed tick that carries Lyme disease can be found.
Video ReportSpringtime is finally upon us again and as people head back outside to enjoy the outdoors they increase their chances of getting bit by a tick.

While bloodsucking ticks can lay waste to a moose and infect humans with devastating diseases, the tiny parasites and the bacteria they carry have no apparent effect on one wee woodland creature: the white-footed mouse.
The next time you see a opossum playing dead on the road, try your best to avoid hitting it. Because it turns out that opossums are allies in the fight against Lyme disease.
What if we could vaccinate the white-footed mice that account for the majority of the transmission of Borrelia burgdorferi (the cause of Lyme disease) and significantly reduce the level of tick infection?
We often blame white-tailed deer and the deer ticks they carry for spreading Lyme disease in the United States, especially from Minnesota to New England to Northern Virginia.
In the Northeast, the black-legged ticks (Ixodes scapularis) that spread Lyme disease also infect people with other maladies, among them anaplasmosis, babesiosis, and – as a new paper in the journal Parasites and Vectors reports – Powassan encephalitis.
Initially, Rick Ostfeld’s work at the Cary Institute focused on how small mammals shape forests. Early on, he noticed a unique relationship among mice, black-legged ticks, and the bacterium that causes Lyme disease.
The New Yorker reports on the controversy surrounding the diagnosis and treatment of Lyme disease. Columnist Michael Specter interviewed Cary disease ecologist Richard Ostfeld about the ecology of ticks and the spread of the disease.
VideoThree members of Congress joined forces with a Lyme disease advocacy group to host a forum to discuss the fight against tick-borne diseases. As a panelist, Cary's Rick Ostfeld shared his research and insights.
Given the 300,000 new cases of Lyme disease a year in the US reported by the CDC, it is understandable that health organizations and local governments in this country are extremely anxious to develop a broader, more effective tick-borne diseases control strategy.
