BACKGROUND Lyme disease is a widespread cosmopolitan zoonosis caused by species belonging to the genus Borrelia. It is transmitted from animal reservoir hosts to humans through hard - ticks of genus Ixodes which are vectors of the disease. CASE PRESENTATION Borrelia burgdorferi sensu lato infection was identified in a marbled polecat, Vormela peregusna, and two European minks, Mustela lutreol...

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...

AIMS Previous studies investigating the link between infection with Borrelia burgdorferi and morphoea have produced conflicting results. Often, these studies have been undertaken in patients from different regions or countries, and using methods of varying sensitivity for detecting Borrelia burgdorferi infection. This study aimed to establish whether a relation could be demonstrated in the High...

The etiologic agent of Lyme borreliosis, Borrelia burgdorferi sensu lato, has been isolated from many biologic sources in North America and Eurasia, and isolates have been divided into three distinct genospecies (B. burgdorferi sensu stricto, Borrelia garinii, and Borrelia afzelii). In order to explore the possible association of genospecies with disease manifestation, 60 isolates of B. burgdor...

Invasive vertebrate species can act as hosts for endemic pathogens and may alter pathogen community composition and dynamics. For the zoonotic pathogen Borrelia burgdorferi sensu lato, the agent of Lyme borreliosis, recent work shows invasive rodent species can be of high epidemiological importance and may support host-specific strains. This study examined the role of gray squirrels (Sciurus ca...

Borrelia burgdorferi sensu stricto isolates from patients with erythema migrans in Europe and the United States were compared by genotype, clinical features of infection, and inflammatory potential. Analysis of outer surface protein C and multilocus sequence typing showed that strains from these 2 regions represent distinct genotypes. Clinical features of infection with B. burgdorferi in Sloven...

Human Lyme borreliosis (LB) is the most prevalent arthropod-borne infection in temperate climate zones around the world and is caused by Borrelia spirochetes. We have identified 10 variable-number tandem repeat (VNTR) loci present within the genome of Borrelia burgdorferi and subsequently developed a multiple-locus VNTR analysis (MLVA) typing system for this disease agent. We report here the su...

Atrophoderma of Pasini and Pierini is a form of dermal atrophy that manifests as either single or multiple, sharply demarcated, hyperpigmented, non-indurated patches. These patches are marked by a slight depression of the skin, with an abrupt edge (i.e., the "cliff-drop" borders), usually located on the backs of adolescents or young adults. The pathophysiology of the disease is unknown, but som...

A critical analysis of two treatment trials of Chinese rhesus macaques infected with Borrelia burgdorferi indicates that insufficient attention was placed on documenting the blood levels, pharmacokinetics, and pharmacodynamic parameters of the antibiotics used in this host. Consequently, it is impossible to conclude that the findings have validity in judging the efficacy of doxycycline or ceftr...

The sensitivity of Borrelia burgdorferi sensu lato to animal sera was analyzed. Complement-mediated borreliacidal effects were observed with particular combinations of host serum and Borrelia genospecies. The species-specific pattern of viability and/or lysis is highly consistent with the pattern of reservoir competence of hosts for B. burgdorferi sensu lato, suggesting a key role of complement...
