Fitness variation of Borrelia burgdorferi sensu stricto strains in mice.
Lyme borreliosis in North America is caused by the tick-borne spirochete Borrelia burgdorferi, a zoonotic bacterium that is able to persistently infect a wide range of vertebrate species. Given the pronounced strain structure of B. burgdorferi in the northeastern United States, we asked whether the fitness of the different genotypes varies among susceptible vertebrate hosts. The transmission dy...
متن کاملEvidence for Host-Genotype Associations of Borrelia burgdorferi Sensu Stricto.
Different genotypes of the agent of Lyme disease in North America, Borrelia burgdorferi sensu stricto, show varying degrees of pathogenicity in humans. This variation in pathogenicity correlates with phylogeny and we have hypothesized that the different phylogenetic lineages in North America reflect adaptation to different host species. In this study, evidence for host species associations of B...
متن کاملBorrelia burgdorferi sensu lato in Ixodes ricinus ticks collected from migratory birds in Southern Norway
BACKGROUND Borrelia burgdorferi sensu lato (s.l.) are the causative agent for Lyme borreliosis (LB), the most common tick-borne disease in the northern hemisphere. Birds are considered important in the global dispersal of ticks and tick-borne pathogens through their migration. The present study is the first description of B. burgdorferi prevalence and genotypes in Ixodes ricinus ticks feeding o...
متن کاملPrevalence of Borrelia burgdorferi sensu lato in ticks collected from migratory birds in Switzerland.
The prevalence of ticks infected by Borrelia burgdorferi sensu lato on birds during their migrations was studied in Switzerland. A total of 1,270 birds captured at two sites were examined for tick infestation. Ixodes ricinus was the dominant tick species. Prevalences of tick infestation were 6% and 18.2% for birds migrating northward and southward, respectively. Borrelia valaisiana was the spec...
متن کاملDifferences in Genotype, Clinical Features, and Inflammatory Potential of Borrelia burgdorferi sensu stricto Strains from Europe and the United States
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...
