Prevalence of Borrelia burgdorferi sensu lato-infected ticks on migrating birds

Article Abstract:

Birds may make a significant contribution to the distribution of Lyme disease Borrelia spirochetes in Europe. Over 98% of the ticks collected in an examination of 22,998 birds caught at eight bird observatories in Scandinavia were Ixodes ricinus, the main species that transmits the Lyme disease pathogen Borrelia burgdorferi. Immunofluorescence and DNA analysis revealed that the Borrelia burgdorferi sensu lato species isolated from the birds made up a heterogeneous group that had previously been observed in Europe.

Genetic diversity of Borrelia burgdorferi sensu stricto in Peromyscus leucopus, the primary reservoir of Lyme disease in a region of endemicity in southern Maryland

Article Abstract:

A study examined the genetic diversity of circulating borreliae in the reservoir population from a large region of western coastal plains of southern Maryland, where incidence of human Lyme disease (LD)cases are reported. Results indicate that the information regarding Borrelia burgdorferi variants found in rodent reservoirs, especially Peromyscus leucopus is useful not only in understanding the complete enzootic cycle of LD but is also important for understanding potential disease outcomes in humans.

Differential transmission of the genospecies of Borrelia burgdorferi sensu lato by game birds and small rodents in England

Article Abstract:

Research was conducted to examine the genetic diversity of Borrelia burgdorferi sensu lato found in southern Britain. The PCR method was used for a more accurate assessment of the diversity and distribution of borreliae in nature. Results suggest that B burgdorferi sensu lato can be maintained in nature through the use of distinct transmission cycles with the same vector tick species but having different vertebrate host species.
