Category hierarchy: Biomes | Geology | Fossils & ArtifactsDescription: Trilobite fossil, an extinct marine invertebrate. Item originally from the United States.Capture device: Camera: Nikon D80Original date: 20080221Locality: Latitude: 3.743160000000000e+001; Longitude: -7.865689999999999e+001

An electron photomicrograph of two spiral-shaped Treponema pallidum bacteria.Created: 1969

Under a magnification of 201X, this scanning electron micrographic (SEM) image depicted a dorsal view of an unidentified engorged female tick, which had been extracted from the skin of a pet cat while in the process of obtaining its blood meal. Note the presence of some of the cat’s fur, along with some of its skin tissue in which the tick’s gnathosoma were still embedded. See PHIL 9972 and 9973 for additional, less magnified views of this scenario. It is from the basis capituli that the two spread pedipalps, and hidden skin-piercing hypostome and chelicerae emanate. On the dorsal surface of the basis capituli you’ll see two depressed areas known as the porose areas, through which secretions produced by dermal glands are released.Created: 2006

Treponema pallidum, darkfield preparation.Created: 1971

Under a low magnification of 100X, this scanning electron micrographic (SEM) image depicted a dorsal view of an unidentified engorged female tick, which had been extracted from the skin of a pet cat while in the process of obtaining its blood meal. Note the presence of some of the cat’s fur, along with some of its skin tissue in which the tick’s gnathosoma were still embedded.

Description: English: The spirochete is a form of bacteria that results in lyme disease. It is characterized by its spiral formation. In addition to its spring-like shape, a spirochetal bacteria has filaments on the outside of its protoplasma. These filaments allow the bacteria to move while continuously rotating in place. Such placement of the flagella on a spirochete makes it easier for it to move throughout the bloodstream. Spirochetal bacteria also have the ability to cloak themselves within the bilayer of a cell, thereby avoiding detection from the immune system. This form of evasion makes it possible for a spirochete to remain dormant for long periods of time (by invading intracellular spaces). Date: 29 May 2012. Source: Own work. Author: Cvolk12.

Description: English: Drawing of spirochaete's mobility system (with internal flagellae) Français : Schéma de principe du positionnement de flagelles internes d'un spirochète (ex : Borrelia). Le nombre de flagelles varie selon les espèces. les flagelles (en rouge et orange), internes, sont accrochées aux deux extrémités de la bactérie. Ils lui offrent une motricité inhabituelle et très performante, à condition d'être dans un milieu qui lui convient, c'est à dire ayant la consistance d'un gel (synovie, humeur vitreuse, etc). Ex : Borrelia burgdorferi se déplace à une vitesse moyenne de 1636 micromètres par minute (moyenne pour 28 bactéries observées), avec une vitesse maximale de 2800 µm/mn chez 3 des bactéries observées, soit la vitesse la plus rapide enregistrée pour un spirochète, et de deux ordres de grandeur au-dessus de la vitesse d'un polynucléaires neutrophiles humain réputé être la plus rapide de nos cellules mobiles.
