Tracking the terrain where ticks are carrying disease in CT


On a sunny, cool day when winter fell to winter, a team of biologists and technicians pulled bright clothes through the pressure on the farm at Lord Creek Farm in Lyme. They were looking for false ticks, carrying Lyme disease and four other fatal illnesses.

As ticks attached to the cloth, the staff counted them and put them in jars for further study at their laboratory at Connecticut Agricultural Experiment Station in New Haven. Japanese tow bushes grew thick under the trees at this private horseshoe farm that has cooperated for many years with Lyme disease researchers.

As the group drew clothes, they noticed ticks on each other's feet and coats, and began to pick them out. This seems to have created what the team leaders, biologists Scott C. Williams and Megan Linske, found in one of their previous studies: ticks are growing more than Japanese barberry, with leaves and thorns all over the country. years, than in landscapes without barberry.

About an hour earlier, the team conducted one survey on The Preserve – public land in Old Saybrook. This forest has no visible tow and there are few invasive plants.

During 2019, scientists sampled 40 afforested areas in all corners of Connecticut. This study aims to calculate the landscapes that attract ticks and is not. The early results, which they produced for the first time last week, show the great density of ticks carrying Lyme and four other diseases. In Fairfield and Litchfield counties, scientists received more than 20,000 biting ticks for each square person. The densities were almost as high in New Haven and New London, with more than 18,000 and almost 17,000 ticks per square mile respectively.

His samples reveal tickets the grim truth about how Lyme's disease increases in ticks if they survive in adults. Only 15% of the niches (young ticks) collected by the team carry Lyme, but within a year after carrying mice carrying the disease, almost half of an adult tick has Lyme disease. Nymphs are a threat to people because they are so small that their bites are often not recognized.

Lyme's home, of course, is like zero land for Lyme disease, which was discovered in the 1970s. Lyme disease and four other deadly diseases occur at the false ticks: anaplasmosis, miyamotoi borrelia disease, babesiosis, and Powassan virus.

Williams stated that the Powassan infection was low in 2019, with only five cases in the state. But Powassan is a dangerous illness. Got Post U. Sen Hagen from North Carolina died in Powassan in October. Comhdháil is considering a bill named Kay Hagan Tick Act for funding research on printed diseases.

Lyme disease is a national health crisis. It causes a microscopic spirochete that enters the bloodstream and hides in the tissues. In 2018, Connecticut was ranked fourth in the nation for Lyme cases, with 1,859 new cases reported that year, the Disease Control and Prevention Centers (CDC) said. But the actual cases are likely 10 times that number (or about 18,500), and the CDC reported.

Across the country, the CDC estimates 300,000 cases per year. In 2015, a study at Johns Hopkins University estimated that up to 440,000 new cases of Lyme are diagnosed each year, costing the health system $ 712 million to $ 1.3 billion a year.

How to help check box checkboxes

Home owners should tow Japanese tow to cut back on their property every five years.

Change clothes after joining. Scientists often put their clothes into a dryer.

If you spend time stretching outdoors, people may prefer to treat protective clothing with an insecticide, available through outdoor outfits.

Changing state forests

Lyme's disease has been around for thousands of years. It became a tick that people believe as the landscape is in favor of those ticks now.

Since 1900 Connecticut has largely moved from farmland to small forest patches affected by grassland areas. All the success of the white fever and the white background is white, two important animals that must survive blood ticks.

While 60% of Connecticut is a forest, much of this afforested land is cut into narrow segments. Such fragmented woods create many places on the edge of the woods where sunlight stimulates the bushes that deer eat – and where ticks survive.

At a forum on urban forests three months ago, Williams told a group of scientists and amateurs that deer created landscapes that like ticks. They eat native plants and leave behind invasive plants that usually shelter the ticks through the winter.

Both scientists said the time came to understand why these forests have ticks. At the same forum, Linske called the lifespan of the tick was “quite the process.” It is like this:

In the first year of ticks, as nymphs, they feed on mice. Not all ticks are infected, but those that put the diseases forward to the mice. The mice then pass on these diseases to other untapped ticks that bite them.

After feeding, the ticks hit the mice. They then spend another season feeding other animals, especially deer. Thousands of ticks can be found feeding on individual deer.

Unlike mice, teeth can not be spread with other ticks from their body. The most important roles that the Lyme deer have to spread are to supply blood meals to ticks just before they lay their eggs.

It is called the “deer tick.” The trumpet would be to call Connecticut as a deer landscape. Williams said that deer do not put Lyme disease on the way mice do, but deer are vital to keep ticks healthy so that they can lay their eggs. Seed deer also spread a number of plants that encourage ticks.

“This is an important study, and it is hoped that it will continue every year. federal funding to continue sampling.

Their work could better define areas where people are more likely to promote dangerous diseases. And it will help Connecticut residents get a better understanding of how to avoid ticks.
