CanLyme is dedicated to promoting advancements in Lyme disease research. More research is needed to accurately diagnose and treat Lyme disease and other tick-borne illnesses and CanLyme has taken measures to address this, see our Venture Grants Policy.

CanLyme board member Reuben Kaufman, PhD has an ambitious tick study project underway on Salt Spring Island, BC and his program is also able to feed ticks to another CanLyme board member Janet Sperling who is completing her doctorate on examining the various pathogens that are found in the guts of Canadian ticks.

Detection of tick-borne infection in Morgellons disease patients by serological and molecular techniques

Marianne J Middelveen, Iris Du Cruz, Melissa C Fesler, Raphael B Stricker, Jyotsna S Shah 1Atkins Veterinary Services, Calgary, AB, Canada; 2IGeneX Laboratories, Palo Alto, CA, USA; 3Union Square Medical Associates, San Francisco, CA, USA Background: Morgellons disease (MD) is a skin condition associated with Lyme disease (LD) and tick-borne illness. Patients with this skin disorder experience ulcerative lesions that contain multicolored filamentous collagen and keratin inclusions. Continues →

Tick-borne disease is multiple microbial in nature

Nov. 1, 2018 A study recently published in Scientific Reports discovered that 65% of Lyme disease patients irrespective of their disease stage respond to several microbes. As a consequence, the authors have demonstrated that microbial infections in individuals suffering from Lyme disease do not follow the “one microbe, one disease” status-quo. Moreover, the probability that Lyme disease patients would respond Continues →

Mount Allison University’s Lyme Research Network presents their 2017 – 2018 report on research funded by the Canadian Lyme Disease Foundation

Another successful year building capacity and knowledge within the Canadian science community. These funded students will be our near-future experts. “Overview On May 2017, Mount Allison University announced the formation of the Mount Allison Lyme Research Network, formed with support of the Canadian Lyme Disease Foundation. This network consists of 14 researchers united to provide a comprehensive approach to Lyme Continues →

Canadian Lyme disease patient groups united in rejecting the ‘one research network only’ concept of the federal government

[CanLyme Note: There is already another pan-Canadian research network that has been up and running for over a year, the Canadian Lyme Consortium. This network works closely with the patient groups together with physicians and scientists and has from it’s formation.] Joint press release “Lyme patient groups from across Canada are unified in their concern over the federal Minister of Health’s Continues →

Genome-wide analysis of Borrelia turcica and ‘Candidatus Borrelia tachyglossi’ shows relapsing fever-like genomes with unique genomic links to Lyme disease Borrelia.

doi: 10.1016/j.meegid.2018.09.013 September 18, 2018 ABSTRACT Borrelia are tick-borne bacteria that in humans are the aetiological agents of Lyme disease and relapsing fever. Here we present the first genomes of B. turcica and B. tachyglossi, members of a recently described and rapidly expanding Borrelia clade associated with reptile (B. turcica) or echidna (B. tachyglossi) hosts, transmitted by hard ticks, and Continues →

One in three ticks in Canada’s capital, Ottawa, carries Lyme disease yet no help for the tens of thousands chronically ill across the country due to false information.

[CanLyme note: For decades Canadian health care leadership have downplayed the prevalence of Lyme disease (borreliosis) in ticks based upon poor surveillance protocol while ignoring reams of published research. They further downplayed the prevalence of this disease in humans with an outrageous, dangerous and deadly adherence to a testing policy that they knew missed most cases. Canadians must be fearful of Continues →

Lyme disease can be transmitted from tick in 12 hours new research shows.

[CanLyme Note: Will the Canadian government labs and physicians now stop telling everyone they cannot have Lyme because the tick was not attached for 24 or more hours?] Infection Kinetics and Tropism of Borrelia burgdorferi sensu lato in Mouse After Natural (via Ticks) or Artificial (Needle) Infection Depends on the Bacterial Strain ORIGINAL RESEARCH ARTICLE Front.

Neuropsychiatric Lyme Borreliosis: An Overview with a Focus on a Specialty Psychiatrist’s Clinical Practice

Pulished August 25, 2018 Robert C Bransfield Department of Psychiatry, Rutgers-Robert Wood Johnson Medical School, Piscataway, NJ 08854, USA Abstract   There is increasing evidence and recognition that Lyme borreliosis (LB) causes mental symptoms. This article draws from databases, search engines and clinical experience to review current information on LB. LB causes immune and metabolic effects that result in a Continues →

Far-Reaching Dispersal of Borrelia burgdorferi Sensu Lato-Infected Blacklegged Ticks by Migratory Songbirds in Canada

https://doi.org/10.3390/healthcare6030089 Abstract Lyme disease has been documented in northern areas of Canada, but the source of the etiological bacterium, Borrelia burgdorferi sensu lato (Bbsl) has been in doubt. We collected 87 ticks from 44 songbirds during 2017, and 24 (39%) of 62 nymphs of the blacklegged tick, Ixodes scapularis, were positive for Bbsl. We provide the first report of Bbsl-infected, songbird-transported I. scapularis in Cape Continues →

Borrelia burgdorferi adhere to blood vessels in the dura mater and are associated with increased meningeal T cells during murine disseminated borreliosis

Published: May 3, 2018 https://doi.org/10.1371/journal.pone.0196893 ABSTRACT Borrelia burgdorferi, the causative agent of Lyme disease, is a vector-borne bacterial infection that is transmitted through the bite of an infected tick. If not treated with antibiotics during the early stages of infection, disseminated infection can spread to the central nervous system (CNS). In non-human primates (NHPs) it has been demonstrated that the Continues →

Whole genome sequencing and phylogenetic analysis of strains of the agent of Lyme disease Borrelia burgdorferi from Canadian emergence zones.

S. Tyler, et al  July 2018 Abstract Lyme disease is emerging in southern Canada due to range expansion of the tick vector, followed by invasion of the agent of Lyme disease Borrelia burgdorferi sensu stricto. Strain diversity, as determined by Multi Locus Sequence Typing, occurs in this zone of emergence, and this may have its origins in adaptation to ecological Continues →

Lyme disease in Saskatchewan ticks, and dog ticks can infect Borrelia miyamotoi.

The vast majority of ticks found in Saskatchewan are Dermacentor variabilis (American dog tick), a species not known to be a competent vector of typical Lyme borreliosis (Borrelia burrgdorferi s.l.) to humans.  However, recently Borrelia miyamotoi has been found in Canadian ticks coast to coast. Also, this from Manitoba, Saskatchewan’s next door neighbour. Borrelia miyamotoi causes similar disease in humans to Lyme borreliosis.
