Pristinaespiralis Courses

Pristina espiralis is a species of single-celled, spiral-shaped bacterium found in a variety of aquatic environments, including aquariums. It was first isolated from aquarium water in 1999, and is interesting for its ability to form complex, helical structures. One of its unusual features is its lack of a flagellum; instead, it moves around by secreting a bubble on one side and gliding on the attached surface. Pristina espiralis is widely studied by scientists interested in understanding the behavior of single-celled organisms. In 2010, it was the first organism to be observed forming a “spiral wave,” a phenomenon caused by the organisms latching onto each other and forming a circular path of motion. Scientists have observed a range of behavior in this organism, including asymmetrical contracting and expanding filaments, pulsating of its cell membrane, and the formation of mucus strings that contain multiple connected cells. In some environments, colonies of Pristina espiralis can be up to 10 centimeters (4 inches) in length. This makes the organism a potential nuisance for aquariums and other aquatic environments, since its presence can interfere with filtration and cause oxygen depletion. Despite this, Pristina espiralis is still of interest to biologists due to its complex, dynamic behavior.
