A spirochaete (/ ˈ s p aɪ r oʊ ˌ k iː t /) [4] or spirochete is a member of the phylum Spirochaetota (also called Spirochaetes [5] / ˌ s p aɪ r oʊ ˈ k iː t iː z /), which contains distinctive diderm (double-membrane) Gram-negative bacteria, most of which have long, helically coiled (corkscrew-shaped or spiraled, hence the name) cells ...

spirochete, (order Spirochaetales), any of a group of spiral-shaped bacteria, some of which are serious pathogens for humans, causing diseases such as syphilis, yaws, Lyme disease, and relapsing fever. Examples of genera of spirochetes include Spirochaeta, Treponema, Borrelia, and …

Spirochaete bacteria are a group of spiral-shaped, motile bacteria that are characterized by their unique flagella and flexible cell walls. They are found in diverse environments, including soil, water, and the gastrointestinal tracts of animals.

Spirochetes are extracellular bacteria, helically shaped with multiple flagella and measuring 10–30 μm in length. Up to now, around 21 genospecies causing Lyme borreliosis were described in the group of B. burgdorferi (sl), but new species have been described now ( …

The Spirochaetaceae are a family of spirochete bacteria. Some species within this family are known to causes syphilis, Lyme disease, relapsing fever, and other illnesses. [1] The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [2] and National Center for Biotechnology Information (NCBI).

Spirochetes are a phylum of bacteria characterized by long, helically coiled cells. These bacteria have lengthwise flagella, called axial filaments, which allow the spirochetes to move. There are three groups of spirochetes implicated in human disease: Treponema, which causes syphilis and the nonvenereal treponematoses; Borrelia, which causes ...

Spirochetes are long, slender bacteria, usually only a fraction of a micron in diameter but anywhere from 5 to 250 μm long. The best known spirochetes of clinical importance are those that cause disease.

Bacteria are classified by shape into three primary groups: cocci, bacilli, and spiral-shaped. The cocci are round, the bacilli are rods, and the spiral-shaped bacteria are either rigid (spirilla) or flexible (spirochetes). These three primary bacteria shapes determine the bacteria’s morphological characteristics.

Spirochaete Bacteria are a distinctive group in the bacterial kingdom, characterised by their corkscrew shape, which allows unique modes of motility, helping them penetrate viscous materials or tissues within hosts.

2024年11月23日 · 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 capable of thriving in anaerobic environments.
