UNLABELLED Lyme disease is a tick-borne illness caused by the bacterium Borrelia burgdorferi, and approximately 10 to 20% of patients report persistent symptoms lasting months to years despite appropriate treatment with antibiotics. To gain insights into the molecular basis of acute Lyme disease and the ensuing development of post-treatment symptoms, we conducted a longitudinal transcriptome st...

The Lyme disease controversy can be largely linked to the misconception that neurobehavioral effects of illness constitute evidence of nervous system infection. Appropriate differentiation between neuroborreliosis (nervous system Borrelia burgdorferi infection) and Lyme encephalopathy (altered nervous system function in individuals with systemic but not nervous system infection)-or encephalopat...

Evidence-based guidelines for the management of patients with Lyme disease were developed by the International Lyme and Associated Diseases Society (ILADS). The guidelines address three clinical questions - the usefulness of antibiotic prophylaxis for known tick bites, the effectiveness of erythema migrans treatment and the role of antibiotic retreatment in patients with persistent manifestatio...

OBJECTIVES Lyme disease is the most common tick-borne disease. People seek health information on Lyme disease from YouTubeTM videos. In this study, we investigated if the contents of Lyme disease-related YouTubeTM videos varied by their sources. METHODS Most viewed English YouTubeTM videos (n = 100) were identified and manually coded for contents and sources. RESULTS Within the sample, 40 v...

Lyme disease or Lyme borreliosis is an emerging infectious disease produced by Borrelia burgdorferi sensu lato, which is a bacteria transmitted to the host organism by the bite of Ixodes ticks. In this report we present the general knowledge about the etiological agent, clinical manifestations of the disease and diagnostic laboratory tests. We offer cumulative information about Lyme disease in ...

Fourteen cases of Lyme arthritis are reported. The most frequent picture was that of oligoarthritis appearing in that part of the leg where the cutaneous or neurological complications, or both, of Lyme disease had developed before the arthritis. In most cases recovery followed a single 10 day course of intravenous (IV) penicillin therapy. Arthritis was the presenting feature of Lyme disease in ...

A treponema-like spirochete was detected in and isolated from adult Ixodes dammini, the incriminated tick vector of Lyme disease. Causally related to the spirochetes may be long-lasting cutaneous lesions that appeared on New Zealand White rabbits 10 to 12 weeks after infected ticks fed on them. Samples of serum from patients with Lyme disease were shown by indirect immunofluorescence to contain...

In Connecticut and the northeastern United States, the blacklegged tick, Ixodes scapularis (commonly known as the deer tick) is the vector for four disease agents; Borrelia burgdorferi, Anaplasma phagocytophilum, Babesia microti, and the deer tick virus (DTV) that cause Lyme disease, human granulocytic anaplasmosis, human babesiosis, and Powassan encephalitis, respectively. There are around 3,0...

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans by the bite of infected black-legged 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., ...

The interpretation of serological results for patients who had Lyme disease many years ago is not well defined. We studied the serological status of 79 patients who had had Lyme disease 10-20 years ago and did not currently have signs or symptoms of active Lyme disease. Of the 40 patients who had had early Lyme disease alone, 4 (10%) currently had IgM responses to Borrelia burgdorferi, and 10 (...
