Source: Eggers, C. H. Phage-Mediated Genetic Manipulation of the Lyme Disease Spirochete Borrelia burgdorferi. J. Vis. Exp. (2022).This video demonstrates the isolation of borrelial phage particles from a Borrelia burgdorferi suspension using polyethylene glycol-mediated phase separation. The sample is centrifuged, treated with a salt solution, and a molecular crowding agent to precipitate phages. Chloroform extraction is done to remove debris and concentrate phage particles. The purified phage...

Source: Eggers, C. H. Phage-Mediated Genetic Manipulation of the Lyme Disease Spirochete Borrelia burgdorferi. J. Vis. Exp. (2022)This video demonstrates the preparation of a genetically modified Borrelia burgdorferi culture engineered with dormant bacteriophage DNA carrying an antibiotic resistance gene. Following antibiotic selection and incubation, a chemical inducer triggers DNA damage, leading to excision, replication, and assembly of new virions containing the resistance gene. After a...

Simulating Colonization and Extinction on Islands ExpandForm groups of three. One member of the group will simulate colonization by throwing balls into the groups of cups representing the islands. Another will simulate extinction by rolling dice to randomly remove balls from the cups. The third group member will record the data. Take time to familiarize yourself with the four island stations. NOTE: There are two large islands with 12 cups and two small islands with 6 cups. Two of the stations...

Species Distribution and Biogeography - Concepts

2019
Species Distribution Biogeography is the study of species distribution across geographic space and the processes that shape these distributions. This discipline is based on the assumption that each species within a location must have immigrated from another geographic area or evolved from a local species. Within each habitat, a variety of biotic and abiotic factors act on individual species to shape birth, death, immigration, and emigration rates. To avoid local extinction, the combined birth...

2022
In vitro culture is a direct detection method for the presence of living bacteria. This protocol describes methods for the culture of diverse Borrelia spirochetes, including those of the Borrelia burgdorferi sensu lato complex, relapsing fever Borrelia species, and Borrelia miyamotoi. These species are fastidious and slow growing but can be cultured.
FAQs
Borrelia species can alter surface antigens, changing the molecular targets recognized by host antibodies. This variation may reduce the effectiveness of antibody-mediated clearance and support continued persistence in vertebrate hosts. Studying these changes helps immunologists explain why protective immunity can be difficult to achieve and why antigen selection matters for vaccine design.
Periplasmic flagella enable Borrelia to move through tissues despite being located within the space between the bacterial membranes. This specialized motility supports interactions with host environments and may influence how the organisms reach or persist in different tissue sites. Their contribution makes bacterial movement an important mechanism in studies of infection and host-pathogen interaction.
Transmission depends on interactions among Borrelia, tick vectors, and vertebrate reservoirs. These relationships provide the biological context in which the bacteria move between hosts and maintain infection cycles. Examining both vector and reservoir stages helps researchers connect bacterial persistence with epidemiology, clarify transmission patterns, and identify points relevant to surveillance or intervention.
Species-level identification can use culture, molecular assays, or sequencing. These approaches provide complementary ways to distinguish organisms and support more precise characterization of infection. Accurate identification improves diagnosis and epidemiological surveillance by linking detected bacteria to particular species, helping researchers monitor distribution and investigate patterns of transmission.
Borrelia species provide models for examining antibody-mediated clearance, antigenic variation, host inflammation, and protective immunity. Researchers can use these organisms to connect changes in bacterial surface antigens with immune recognition and inflammatory responses. This work helps define how infection persists, how hosts respond, and which immune mechanisms may contribute to effective protection.
Mechanistic studies of Borrelia species reveal how bacterial persistence, antigenic variation, transmission, and host inflammation interact. Those findings can guide selection of vaccine targets and clarify biological processes relevant to treatment strategies. Species-level information is also valuable because it connects laboratory observations with diagnosis, surveillance, and the distinct epidemiological contexts of infection.
