Tick species are undergoing range expansions across Canada due to global warming, animal migration, and land fragmentation. It is estimated that their range is expanding northwards by 35–55km per year. Species posing the greatest risk to humans are the Ixodes scapularis (blacklegged tick) and the Ixodes pacificus (Western blacklegged tick). The risk of human tick-borne infections is increasing. Populations…
“Spiroplasma spp. are intracellular organisms that belong to the class Mollicutes, which include Mycoplasma spp. These bacteria have a single-layer cell membrane, cannot be visualized by Gram staining, require special substrates for growth, and can be diagnosed by genetic methods (6). Plants, insects, and ticks are known reservoirs (7). S. ixodetis was initially reported in…
Abstract Ixodes scapularis is currently known to transmit 7 pathogens responsible for Lyme disease, anaplasmosis, babesiosis, tick-borne relapsing fever, ehrlichiosis, and Powassan encephalitis. Ixodes scapularis can also be colonized by endosymbiotic bacteria including those in the genus of Rickettsia. We screened 459 I. scapularis ticks submitted to the Connecticut Agricultural Experiment Station Tick Testing Laboratory with the objectives to (1) examine…
People have ‘let their guard down’ and aren’t checking for ticks as weather cools, says zoologist Laurenne Schiller loves taking her dog Cousteau for walks along Halifax trails as the weather cools. But even after the first dusting of snow this week, each walk finishes with a head-to-toe check for blacklegged ticks on her…
Nov 26th, 2018 Ehrlichiosis “Ehrlichiosis is a disease caused by several Gram-negative obligate intracellular bacteria that are transmitted by a tick vector. The frequency of ehrlichiosis is increasing, which is ascribed to the increased awareness and diagnostic availability, as well as the expansion of regions populated with the most common tick vector – Amblyomma americanum (also known…
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…

Technological advances in high throughput sequencing have given an unprecedented opportunity to comprehensively characterize bacterial associates of ticks, but recent studies have used different 16S rRNA variable regions and sequence read lengths with little consideration of…

[CanLyme note: A good take home message from this article linked below is that for government to focus heavily on only known areas where ticks are established, is misguided. Canada is comprised of millions of square kilometers. Less than one percent of one percent are looked at for Lyme disease in nature. If you have…

Thursday, September 24th, 2015 Ticks carrying the debilitating Lyme disease have been found in London’s Richmond Park, according to university scientists. Researchers from the London School of Hygiene and Tropical Medicine warned visitors to exercise caution in order to avoid contracting the bacterial infection, which can be passed on to humans via bites from the…
By Stacey Oke, DVM, MSc June 17, 2015 The Horse magazine Spring has sprung … and so have the ticks. With some of those ticks comes the risk of your horse contracting Lyme disease, an infection caused by the bacterium Borrelia burgdorferi. Lyme disease is transmitted mainly viaIxodes ticks, which pass the bacteria from infected…
