Study Summary
Background: Lyme disease is an infection caused by Borrelia burgdorferi, a bacteria that is transmitted to humans by ticks. It can cause many different symptoms including rash, fever, headache, meningitis (infection of the central nervous system), and arthritis. While most patients improve after taking antibiotics, some patients continue to have symptoms. It is currently unknown why some patients continue to have symptoms. One possibility is that the antibiotics have not successfully gotten rid of all of the bacteria. Current tests for Lyme disease cannot tell whether the bacteria have been successfully eliminated from the body. Xenodiagnosis is a way to look for Borrelia bacteria using the animal that usually hosts them, Ixodes scapularis (also known as the deer tick). This method takes advantage of the evolution of the bacteria and the insect that transmits the infection, which can make the insect particularly good at finding the agent. In studies of animals, xenodiagnosis may be more sensitive than current tests for detecting the presence of the Lyme disease bacteria. Researchers are interested in using xenodiagnosis to determine whether uninfected ticks that feed on humans who have been infected with Lyme disease bacteria can detect the continued presence of live bacteria. Objectives: \- To determine whether xenodiagnosis can be used to successfully investigate the presence of Lyme disease bacteria. Eligibility: 1. Individuals at least 18 years of age who are in one of the following categories: 2. Have had the erythema migrans rash (a symptom of Lyme infection) and received antibiotic therapy less than 4 months ago (but have not had antibiotics in the previous month). 3. Have the erythema migrans rash and received less than 2 days of antibiotic therapy. 4. Have been diagnosed with early or late Lyme disease, have received antibiotic therapy, but still have high levels of antibodies against the bacteria at least 6 months after therapy, and have not received
