Genetic Manipulation of Borrelia Spp

Area of Science:

• Microbiology
• Genetics
• Infectious Diseases

Background:

• Borrelia (Borreliella) burgdorferi and Borrelia hermsii are spirochetes responsible for Lyme disease and relapsing fever.
• These pathogens exhibit highly unusual, segmented, and predominantly linear genomes.
• Genetic investigation of Lyme disease spirochetes is advanced, while relapsing fever spirochete genetics is emerging.

Purpose of the Study:

• To highlight the sophisticated genetic tools available for studying Borrelia species.
• To emphasize the growing understanding of Borrelia cellular physiology and pathogenesis.

Main Methods:

• Utilizing a range of molecular tools from selectable markers to inducible gene expression systems.
• Employing high-throughput mutagenesis methodologies.
• Overcoming significant experimental challenges in spirochete genetics.

Main Results:

• Sophisticated genetic analyses have significantly advanced the study of Borrelia burgdorferi.
• A growing genetic understanding of relapsing fever spirochetes is being established.
• Molecular tools enable detailed investigation despite experimental hurdles.

Conclusions:

• A robust genetic understanding of spirochete physiology and Lyme disease pathogenesis has been achieved.
• Continued development of genetic tools will further elucidate Borrelia biology and disease mechanisms.
