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 ...
Bacterial motility is the ability of bacteria to move independently using metabolic energy. Most motility mechanisms that evolved among bacteria also evolved in parallel among the archaea. Most rod-shaped bacteria can move using their own power, which allows colonization of new environments and discovery of new resources for survival.
Certain abnormalities on x-ray imaging are commonly observed in DES, such as a "corkscrew esophagus" or "rosary bead esophagus", although these findings are not unique to this condition. Specialized testing called manometry can be performed to evaluate the motor function of the esophagus, which can help identify abnormal patterns of muscle ...
Peristalsis (/ ˌ p ɛr ɪ ˈ s t æ l s ɪ s / PERR-ih-STAL-siss, US also /-ˈ s t ɔː l-/- STAWL-) [1] is a type of intestinal motility, characterized by radially symmetrical contraction and relaxation of muscles that propagate in a wave down a tube, in an anterograde direction. Peristalsis is progression of coordinated contraction of ...
[2] [30] [31] [32] Spiral bacteria can be sub-classified as spirilla, spirochetes, or vibrios based on the number of twists per cell, cell thickness, cell flexibility, and motility. [ 33 ] Bacteria are known to evolve specific traits to survive in their ideal environment. [ 34 ]
Genlisea (/ ˌ dʒ ɛ n l ɪ ˈ s iː ə / JEN-liss-EE-ə) is a genus of carnivorous plants also known as corkscrew plants. The 30 or so species grow in wet terrestrial to semi-aquatic environments distributed throughout Africa and Central and South America .
Motility is the ability of an organism to move independently using metabolic energy. This biological concept encompasses movement at various levels, from whole ...
Treponema pallidum is a helically shaped bacterium with high motility consisting of an outer membrane, peptidoglycan layer, inner membrane, protoplasmic cylinder, and periplasmic space. [9] It is often described as gram-negative, but its outer membrane lacks lipopolysaccharide, which is found in the outer membrane of other gram-negative ...
