What is a bacteria strain of borrelia vs a bacteria species of borrelia?

A bacteria species of Borrelia refers to a group of bacteria that share common characteristics and genetic makeup, such as Borrelia burgdorferi, which is known to cause Lyme disease. In contrast, a bacteria strain of Borrelia is a specific variant within a species that may exhibit distinct traits, such as differences in virulence, antibiotic resistance, or genetic markers. Strains can arise due to mutations or adaptations to different environments or hosts. Thus, while all strains belong to a species, not all species are composed of the same strains.
