ABSTRACT Birds transport ticks into Canada during northward spring migration, and some of these ticks are infected with tick-borne zoonotic pathogens. Some Amblyomma species harbour pathogens that cause debilitating diseases that can be fatal to humans, and domestic and wildlife animals. At least 65 Amblyomma spp. are indigenous in the Western Hemisphere, and approximately half…
Abstract Mass spectrometry enhanced by nanotechnology can achieve previously unattainable sensitivity for characterizing urinary pathogen-derived peptides. We utilized mass spectrometry enhanced by affinity hydrogel particles (analytical sensitivity = 2.5 pg/mL) to study tick pathogen-specific proteins shed in the urine of patients with (1) erythema migrans rash and acute symptoms, (2) post treatment Lyme disease syndrome (PTLDS), and (3)…
Abstract Lyme disease-causing Borrelia burgdorferi has been reported in 10–19% of Ixodes ticks from Alberta, Canada, where the tick vector Ixodes scapularis is at the northwestern edge of its range. However, the presence of Borrelia has not been verified independently, and the bacterial microbiome of these ticks has not been described. We performed 16S rRNA bacterial surveys on female I. scapularis from Alberta that were…
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…
[CanLyme Note: The Canadian medical community is absolutely under-informed on tick-borne disease. Medical leadership in Canada, managed by non-medical (PHAC), medically unethical (AMMI), scientifically unethical (CIHR), taxpayer funded gatekeepers for the for-profit medical industry insure never ending sickness that generates billions of dollars while denying access to policy making decisions of those most affected… patients and…
[CanLyme Note: In the western regions of North America Dermacentor andersonii is a major vector of Rickettsia rickettsii. Because rickettsial infections in humans appear to be expressed from mild to fatal it is possible many misdiagnoses have occurred over the decades. “Rickettsial infections can affect many organs, including the central nervous system (CNS) ” Also, the possibility of…
[CanLyme Note: ‘No Tick is a Good Tick’ Canadian ticks are equally co-infected.] https://doi.org/10.1016/j.ttbdis.2019.06.001 Abstract Fifty nymphal Ixodes ricinus ticks collected in Alsace, France, identified by morphological criteria and using MALDI-TOF MS, were tested by PCR to detect tick-associated bacteria and protozoan parasites. Seventy percent (35/50) of ticks contained at least one microorganism; 26% (9/35) contained two or…
LYME SCI: Re-cap of New York’s Lyme disease hearing On August 29, the New York State Senate’s Task Force on Lyme and Tick-borne Diseases held a public hearing, with participation from many stakeholders. Public health officials, scientists, patients, and doctors from IDSA and ILADS all addressed the committee hearing, which was streamed live to a…
Alaska Dispatch News Monday, August 29th, 2016 While Alaskans have long endured dense mosquitoes and frigid air, we’ve always had the absence of venomous snakes and dog ticks. But the latter may be establishing themselves here. Ticks that infest red squirrels, snowshoe hares and a variety of birds have always been present in Alaska, but a…

[CanLyme note: CanLyme has no evidence to support the insinuation of the Entomological Society of America in the last sentence of their statement that there may have been “intentional” introduction of tick-borne diseases.] July 29th, 2015 The Entomological Society of America (ESA) strongly supports building a national strategy using Integrated Tick Management (ITM) to better control…
By Bob McPhail July 17, 2015 A second case of rickettsiosis, a potentially fatal tick-borne bacterial illness, has been reported in Tijuana, state health officials announced on Wednesday, July 15. Earlier reports of the disease had been confined mostly to Mexicali, where, according to multiple news reports, 25 people lost their lives to the illness…
Abstract Rocky Mountain spotted fever (RMSF) is a tick-borne disease caused by R. rickettsii in North and South America. Domestic dogs are susceptible to infection and canine RMSF can be fatal without appropriate treatment. Although clinical signs of R. rickettsii infection in dogs have been described, published reports usually include descriptions of either advanced clinical…
Last Updated: Wednesday, 18 March 2015 07:04 Short-term doxycycline use does not stain kids’ teeth, CDC/IHS study finds March 17, 2015 – Kids are five times more likely than adults to die from tickborne diseases like Rocky Mountain spotted fever (RMSF). Doctors often avoid prescribing doxycycline, the most effective RMSF treatment, for young children because…
