Lyme Disease News and Research

RSS

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans by the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks; laboratory testing is helpful in the later stages of disease. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics. Steps to prevent Lyme disease include using insect repellent, removing ticks promptly, landscaping, and integrated pest management. The ticks that transmit Lyme disease can occasionally transmit other tick-borne diseases as well.

FDA warns against use of "bismacine," also known as chromocine

The U.S. Food & Drug Administration (FDA) is warning consumers and health care providers not to use a product called "bismacine," also known as chromocine.

Climate, deer, rodents, and acorns as determinants of variation in Lyme-disease risk

In the United States, Lyme disease incidence has skyrocketed from 497 cases reported in 1982 (the first year national statistics were collected) to a record 23,763 in 2002.

Unexpected rheumatoid arthritis discovery

What makes joints in people with rheumatoid arthritis, and related conditions like Lyme disease or lupus, so susceptible to attack by the body's immune system, leading to painful flare-ups and deterioration? The answer may surprise you.

Flaviviruses immune system defenses in different ways depending on whether they are transmitted by mosquitoes or ticks

"Flaviviruses exact an enormous toll in terms of illness and death worldwide," notes NIAID Director Anthony S. Fauci, M.D. "Because this is a relatively new field of study, everything we learn about how these viruses operate is significant.

Lyme disease prevention study in 21 Connecticut communities

Researchers at the Emerging Infections Program (EIP) at Yale School of Medicine in partnership with the Connecticut Department of Public Health and the Centers for Disease Control and Prevention have launched a Lyme disease prevention study in 21 Connecticut communities.

Expert warns of spread of Rocky Mountain Spotted Fever

An expert on infectious diseases at Johns Hopkins University School of Medicine, is warning that humans can inadvertently help spread infectious organisms beyond traditional state boundaries.

A sudden increase in the number of British cases of Lyme disease

Lyme disease, an infection carried by ticks causes a rash and stiffness in the joints and, if left unchecked, it can affect the central nervous system, causing tingling in hands and feet, or facial palsy. In the worst cases the disease can also affect the heart, liver and spleen and even lead to encephalitis, which can kill.

Neutrophils dictate whether our immune system will permit or prevent bacterial infections

New research on a bacterium that can survive encounters with specific immune system cells has strengthened scientists' belief that these plentiful white blood cells, known as neutrophils, dictate whether our immune system will permit or prevent bacterial infections.

Intriguing new data on the spread of the Lyme disease bacteria through the blood stream

The ability to find the Lyme spirochete--the tick-borne agent responsible--in the blood is itself an achievement because existing methods of culturing blood were not sensitive enough to detect its presence until College researchers developed a new technique, which they used in the study.

Key advance in understanding the proteins and mechanisms involved in the spread of Lyme Disease

Virginia Commonwealth University scientists have made a key advance in understanding the proteins and mechanisms involved in the spread of Lyme Disease, a finding that could lead to a vaccine against the tick-borne illness that affects thousands of people each year.

Vaccinating mice against Lyme disease could help reduce the risk of transmission of the disease to humans

Vaccinating large populations of white-footed mice against the bacterium that causes Lyme disease could help reduce the risk of transmission of the disease to humans, says a study supported by the National Institute of Allergy and Infectious Diseases (NIAID).

Research opens up new avenues to diagnosis and treat Lyme disease

Researchers at Yale School of Medicine have identified a Lyme disease receptor called TROSPA that is used by disease agents to invade ticks.

Researchers unravel genetic makeup of ticks to tackle disease

Ticks as small as a freckle can transmit a number of illnesses for which there is no vaccine and, in some cases, no cure. These creatures even could become bioterrorism weapons.

As humans alter land, infectious diseases follow

As people remake the world's landscapes, cutting forests, draining wetlands, building roads and dams, and pushing the margins of cities ever outward, infectious diseases are gaining new toeholds, cropping up in new places and new hosts, and posing an ever-increasing risk to human and animal health.

Tips to avoid Lyme disease and West Nile virus

What's bugging you now that spring is here? Probably the same thing that's bugging your child -– mosquitoes, ticks and other flying, crawling, or creeping creatures of the great outdoors. Not only are these bugs' bites and stings painful and itchy, the potential health risk of insect-borne diseases -- such as Lyme disease and West Nile virus

Comparative genomics to cast new light on other spirochete microbes

Three centuries after a pioneering Dutch microbiologist first observed the spiral-shaped oral pathogen Treponema denticola, scientists have deciphered the bacterium’s entire DNA sequence and used comparative genomics to cast new light on other spirochete microbes.
