Lack of familiarity may mean disease goes undiagnosed. Lyme disease in Alberta has the potential to spike in coming years, with new information pointing to an increased population of disease-carrying ticks. “We have found that some of the ticks are present in Alberta and a small number have been found to have Lyme in them,”…
CBC TV Ottawa … Lyme disease ticks likely breeding in Ottawa Ticks carrying Lyme disease are likely breeding in Ottawa, leading to an increase in reported cases, according to a doctor at the Children’s Hospital of Eastern Ontario (CHEO). Lyme disease is a bacterial infection often transmitted by an infected tick and causing muscle pain,…
Despite its many delights, summer also brings its fair share of pestilence. One, called babesiosis, has only recently been widely recognized as a potentially serious outdoor hazard. According to a very detailed study conducted on Block Island, R.I., it could eventually rival Lyme disease as the most common tick-borne ailment in the United States. But…
“Our studies do however offer proof of the principle that intact spirochetes can persist in an incidental host comparable to humans, following antibiotic therapy. Additionally, our experiments uncover residual antigen associated with inflammatory foci.” Embers ME, Barthold SW, Borda JT, Bowers L, Doyle L, et al. (2012) Persistence of Borrelia burgdorferi in Rhesus Macaques following…

Lyme borreliosis (LB) is a tick-borne infectious disease with variable symptoms. The most common manifestation of LB is an expanding rash on the skin but frequently arthritic or neurological and occasionally cardiac or ocular symptoms are seen.
Lyme borreliosis (LB), also known as Lyme disease, is emerging as a serious tick- borne illness across Canada. More than three decades of research on LB in North America and Europe have provided a large, complex body of research involving well-documented difficulties at several levels.
Pathogenic spirochetes are bacteria that cause a number of emerging and re-emerging diseases worldwide, including syphilis, leptospirosis, relapsing fever, and Lyme borreliosis
Spirochetes causing Lyme borreliosis are obligate parasites that can only be found in a tick vector or a vertebrate host. The ability to survive in these two disparate environments requires up and downregulation of specific genes by regulatory circuits that remain largely obscure.
Persistent infection by pathogenic organisms requires effective strategies for the defense of these organisms against the host immune response.
Here we investigate the dynamics of the hepatic intravascular immune response to a pathogen relevant to invariant natural killer T cells (iNKT cells).
The source of sporadic Lyme disease (Lyme borreliosis) across Canada has been a mystery. Several tenets abound about the origin of this bacterial illness, but science is often lacking.
Scott JD, Anderson JF, Durden LA J Parasitol 2011 08 24 Abstract Millions of Lyme disease vector ticks are dispersed annually by songbirds across Canada, but often overlooked as the source of infection. For clarity on vector distribution, we sampled 481 ticks (12 species and 3 undetermined ticks) from 211 songbirds (42 species/subspecies) nationwide. Using…
Benjamin Luft, M.D., Professor of Medicine, Stony Brook University Medical Center, and a team of medical researchers have determined the genetic blueprint of 13 strains of the bacteria that cause Lyme disease. The finding is crucial to advancing research on Lyme disease, the most frequent tick-borne infection in North America and Europe, and may lead to better diagnostics and a vaccine
Borrelia burgdorferi is a causative agent of Lyme disease in North America and Eurasia. The first complete genome sequence of B. burgdorferi strain 31, available for more than a decade, has assisted research on the pathogenesis of Lyme disease.
The Canadian Lyme Disease Foundation is dedicated to promoting research, education, diagnosis and treatment of Lyme and associated diseases.
