Borrelia microtti and Borrelia persica are two Iranian strains of spirochetes whose vectors are Ornithodorous tholozani and Ornithodorous erraticus which are responsible for relapsing fever. BSK medium has been used for in vitro culture of other strains of borrelia, although the two mentioned strains could not be successfully cultured in it. We have modified BSK medium by using guinea pig ...

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 method...

results no borrelia dna was detected by pcr in skin lesions of patients with morphea. patients and methods sixty six patients with morphea were prospectively included in the present study. for each patient, formalin-fixed, paraffin-embedded tissue blocks of skin lesion biopsies were examined for borrelia spp. dna using pcr. objectives we aimed to find the frequency of borrelia in morphea lesion...

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...

It has been known for decades that human Lyme disease is caused by the three spirochete species Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii. Recently, Borrelia valaisiana, Borrelia spielmanii, and Borrelia bissettii have been associated with Lyme disease. We report the complete genome sequences of B. valaisiana VS116, B. spielmanii A14S, and B. bissettii DN127.

Borrelia burgdorferi sensu lato, the spirochete that causes human Lyme borreliosis (LB), is a genetically and phenotypically divergent species. In the past several years, various molecular approaches have been developed and used to determine the phenotypic and genetic heterogeneity within the LB-related spirochetes and their potential association with distinct clinical syndromes. These methods ...

A total of 874 Ixodes ricinus ticks were collected in Switzerland to investigate the genetic diversity of the Borrelia population. We integrated to the RT-PCR method the DNA sequence analysis of a 162-bp fragment of the recA gene. Five genospecies were detected: Borrelia afzelii, Borrelia burgdorferi s.s., Borrelia garinii, Borrelia valaisiana, and Borrelia lusitaniae. A heterogeneous distribut...
