Mayo Researchers Identify New Borrelia Species that Causes Lyme Disease

ByTeam

Article sub-heading: Until now, Borrelia burgdorferi was only species believed to cause Lyme disease in North America [Canlyme note: actually, many scientists and patient advocate groups have been trying for decades to point to the obvious – Lyme disease is a borreliosis caused by many strains/species (genotypes), just as influenza is an illness caused by various…

Borrelia burgdorferi Sensu Lato Spirochetes in Wild Birds in Northwestern California: Associations with Ecological Factors, Bird Behavior and Tick Infestation

ByTeam

Published: February 25, 2015 Abstract Although Borrelia burgdorferi sensu lato (s.l.) are found in a great diversity of vertebrates, most studies in North America have focused on the role of mammals as spirochete reservoir hosts. We investigated the roles of birds as hosts for subadult Ixodes pacificus ticks and potential reservoirs of the Lyme disease…

UC Berkeley: Study IDs key birds that host Lyme disease bacteria in California

ByTeam

[ CanLyme note: Western Canadian ticks often come from migratory birds from California and other western states. Borrelia bissettii was found in the province of British Columbia well over a decade ago, yet there is still no human test that properly tests for it and many other Borrelia genotypes known to occur. Patients in Canada are…

Remarkable diversity of tick or mammalian-associated Borreliae in the metropolitan San Francisco Bay Area, California

ByTeam

Natalia Fedorova, Joyce E. Kleinjan, David James, Lucia T. Hui, Hans Peeters, Robert S. Lane Abstract The diversity of Lyme disease (LD) and relapsing fever (RF)-group spirochetes in the metropolitan San Francisco Bay area in northern California is poorly understood. We tested Ixodes pacificus, I. spinipalpis, and small mammals for presence of borreliae in Alameda…

The prevalence of Borrelia miyamotoi infection, and co-infections with other Borrelia spp. in Ixodes scapularis ticks collected in Canada

ByTeam

Antonia Dibernardo, Tyler Cote, Nicholas H Ogden and L Robbin Lindsay Published: 15 April 2014 Abstract (provisional) Background Blacklegged ticks, Ixodes scapularis are vectors of the tick-borne pathogens Borrelia  burgdorferi, Anaplasma phagocytophilum and Babesia microti. Recently, the I. scapularis-borne   bacterium Borrelia miyamotoi has been linked to human illness in North America. The range of this tick is…

Investigation of Genotypes of Borrelia burgdorferi in Ixodes scapularis Ticks Collected during Surveillance in Canada

ByTeam

Ogden, et al Abstract The genetic diversity of Borrelia burgdorferi sensu stricto, the agent of Lyme disease in North America, has consequences for the performance of serological diagnostic tests and disease severity. To investigate B. burgdorferi diversity in Canada, where Lyme disease is emerging, bacterial DNA in 309 infected adult Ixodes scapularis ticks collected in…
