• "Genus Borrelia" is a scientific term used primarily in biology, medicine, and microbiology.
• It is always capitalized ("Borrelia") as it is a proper noun for the genus name.
• It is often used in contexts discussing infectious diseases, tick-borne illnesses, and bacterial classification.

Examples of Usage

• Scientific Context:
  • The causative agent of Lyme disease is a spirochete belonging to the genus Borrelia.
