Jun 8, 2021 · Spirochetes are long, thin, flexible, spirally coiled helical bacilli. These motile, gram-negative bacilli are classified into eight genera primarily on the basis of habitat, pathogenicity, …

Spirochetes are long and slender bacteria, usually only a fraction of a micron in diameter but 5 to 250 microns long. They are tightly coiled, and so look like miniature springs or telephone cords.

Spirochetes are defined as a phylum of bacteria characterized by long, helically coiled cells that possess axial filaments for movement, with notable groups including Treponema, Borrelia, and Leptospira, …

Spirochetes (spirochaetes) are Gram-negative, spiral-shaped bacteria of the phylum Spirochaetes. In nature, they may exist as free-living bacteria, symbionts, or as parasites capable of causing diseases …

Mar 27, 2024 · Spirochetes are a unique group of bacteria, some of which are responsible for causing significant diseases in humans and animals. Their pathogenicity is attributed to a combination of their …

The spirochaetes belong to a phylum of distinctive double-membrane bacteria that are characterized by their long, spiral-shaped cells. The spirochaetes are chemoheterotrophic in nature, free-living and …
