Give opossums a break

Serving as inadvertent innkeepers for opossums may turn out to be good for your health. Scientists at the Cary Institute of Ecosystem Studies in Millbrook, New York, have learned that opossums act like little vacuum cleaners when it comes to ticks, including those that can spread debilitating Lyme disease to humans and other animals.

Snow protects infected ticks

This frigid, snowy winter may be keeping many people indoors, but is likely doing little to kill slumbering hordes of ticks that can carry Lyme disease.

In a warmer world, ticks that spread disease are arriving earlier, expanding their ranges

In the northeastern United States, warmer spring temperatures are leading to shifts in the emergence of the blacklegged ticks that carry Lyme disease and other tick-borne pathogens. At the same time, milder weather is allowing ticks to spread into new geographic regions.

Bumper acorn crop now, not good news for Lyme disease later

Mice, chipmunks and shrews are welcoming hosts for the bacteria ticks spread. They're plentiful. They're low to the ground, so ticks can easily hop aboard. And they lack the immune systems that might compromise any infectious agents.

Small, fast, and crowded: Mammal traits amplify Lyme disease risk

In the U.S., some 300,000 people are diagnosed with Lyme disease annually. Thousands also suffer from babesiosis and anaplasmosis, tick-borne ailments that can occur alone or as co-infections with Lyme disease.

Four facts about tick-borne illness

Cary Institute scientists have been investigating the ecology of Lyme disease and other tick-borne ailments for more than 20 years. Here are some important tick facts to remember this summer.

Study finds one tick bite can deliver multiple infections

Podcast
A new study in New York reveals that ticks are more likely to be infected with several pathogens, not just the bacterium that causes Lyme disease. The ticks for the study were collected from Dutchess County.

Single tick bite can pack double pathogen punch

People who get bitten by a blacklegged tick have a higher-than-expected chance of being exposed to more than one pathogen at the same time.
