Lyme disease (LD) is a frequent zoonosis found in the Northern Hemisphere and is considered an infectious disease caused by spirochetes belonging sensu lato to the Borrelia burgdorferi complex transmitted by ticks of the Ixodes ricinus group. In 1992, first cases similar to LD were described in Brazil, when brothers, after a tick bite episode developed symptoms , as erythema migrans, general fl...
The Arctic, even more so than other parts of the world, has warmed substantially over the past few decades. Temperature and humidity influence the rate of development, survival and reproduction of pathogens and thus the incidence and prevalence of many infectious diseases. Higher temperatures may also allow infected host species to survive winters in larger numbers, increase the population size...
introduction: to investigate the role of borrelia infections in pathogenesis of multiple sclerosis (ms) the presence of antibody against borrelia persica (the most common species of borrelia in iran) in the serum and csf of ms patients was studied. material and methods: the presence of antibodies against borrelia persica antigens was studied in the serum and csf of 50 ms patients and 30 age and...
introduction: spirochetes of borrelia can be visualized directly in infected ticks by dark-field microscopy. inoculation of in phosphate buffered saline (pbs) suspension of ground argasid soft ticks to susceptible animals or allowing the ticks to feed on the same species followed by microscopic examination of the animals’ blood have also been practiced. with the advent of molecular methods and ...
Relapsing fever Borrelia spp. undergo antigenic variation, achieve high levels in blood, and require rapid production of immunoglobulin M (IgM) for clearance. MyD88-deficient mice display defective clearance of many pathogens; however, the IgM response to persistent infection is essentially normal. Therefore, MyD88(-/-) mice provided a unique opportunity to study the effect of nonantibody, inna...
