    ByCanLyme May 13, 2022May 13, 2022

    Sadly this lack of help for adequate Lyme disease treatment is a Canada-wide problem due in large part to the very poor information given to physicians and other medical professionals by a private self-proclaimed expert group called the Association of Medical Microbiology and Infectious Diseases Canada.  Provincial and federal governments have ceded control over the…

    The Platelet Fraction is a Novel Reservoir to Detect Lyme Borrelia in Blood

    ByCanLyme May 5, 2022July 4, 2025

    Abstract Serological diagnosis of Lyme disease suffers from considerable limitations. Yet, the technique cannot currently be replaced by direct detection methods, such as bacterial culture or molecular analysis, due to their inadequate sensitivity. The low bacterial burden in vasculature and lack of consensus around blood-based isolation of the causative pathogen, Borrelia burgdorferi, are central to this…

    Capture Sequencing Enables Sensitive Detection of Tick-Borne Agents in Human Blood

    ByCanLyme April 17, 2022

    March 7, 2022 Abstract Assay sensitivity can be a limiting factor in the use of PCR as a tool for the detection of tick-borne pathogens in blood. We evaluated the performance of Tick-borne disease Capture Sequencing Assay (TBDCapSeq), a capture sequencing assay targeting tick-borne agents, to test 158 whole blood specimens obtained from the Lyme…

    Two-tier testing no better than a flip of a coin: Molecular Microbiological and Immune Characterization of a Cohort of Patients Diagnosed with Early Lyme Disease

    ByCanLyme April 6, 2022April 6, 2022

    ABSTRACT Lyme disease is a tick-borne infection caused by the bacteria Borrelia burgdorferi. Current diagnosis of early Lyme disease relies heavily on clinical criteria, including the presence of an erythema migrans rash. The sensitivity of current gold- standard diagnostic tests relies upon antibody formation, which is typically delayed and thus of limited utility in early…

    [CanLyme Note: We disagree that “appropriate treatment” has been established for borreliosis. Also, this study involved deceased monkeys and is a primary tissue study so it is not representative of what occurs in a living human. There are interesting point made including that dead borrelia remnants can cause havoc.] Abstract Even after appropriate treatment, a proportion…

    Neuropathogenicity of non-viable Borrelia burgdorferi ex vivo

    ByCanLyme March 29, 2022

    January 2022 Abstract Even after appropriate treatment, a proportion of Lyme disease patients suffer from a constellation of symptoms, collectively called Post-Treatment Lyme Disease Syndrome (PTLDS). Brain PET scan of patients with PTLDS have demonstrated likely glial activation indicating persistent neuroinflammatory processes. It is possible that unresolved bacterial remnants can continue to cause neuroinflammation. In…

    Abstract Introduction. Because patients with a suspicion of Lyme borreliosis (LB) may have experienced difficult care paths, the Tick-Borne Diseases Reference Center (TBD-RC) was started in 2017. The aim of our study was to compare the clinical features of patients according to their final diagnoses, and to determine the factors associated with recovery in the…

    Risk of post-treatment Lyme disease in patients with ideally-treated early Lyme disease: A prospective cohort study.

    ByCanLyme February 16, 2022

    Abstract Purpose Post-treatment Lyme disease (PTLD) is characterized by patient-reported symptoms after treatment for Borrelia burgdorferi infection. The primary aim of this study was to assess whether participants with a history of Lyme disease (LD) would be more likely to meet criteria for PTLD than those without a history of LD. Methods We conducted a longitudinal, prospective…

    Estimating the Frequency of Lyme Disease Diagnoses, United States, 2010–2018

    ByCanLyme February 11, 2022

    Abstract By using commercial insurance claims data, we estimated that Lyme disease was diagnosed and treated in ≈476,000 patients in the United States annually during 2010–2018. Our results underscore the need for accurate diagnosis and improved prevention. Lyme disease is caused by Borrelia burgdorferi spirochetes, which are transmitted to humans by certain Ixodes spp. ticks (1). The infection can…
