It is a special kind of growth of highly motile bactria on culture media. its look like a top view of lady wearing a skirt, so its also known as skirt like appearance. best example of swarmiong growth is Proteus vulgaris.
Logarithmic growth is a pattern where the growth rate of a phenomenon slows over time, forming a curve that gradually levels off. It is characterized by a steep increase initially, followed by a gradual tapering as it approaches an upper limit. This type of growth is common in situations where resources or constraints limit continued exponential growth.
Proteus is a genus of bacteria in the family of Enterobacteriaceae. Proteus species are famous for their swarming on solid culture media. When different Proteus species swarm towards each other, a line of inhibited growth results where strains meet. This was first observed in 1946 by Dienes and is referred to as the Dienes phenomenon.The cause of the formation of a Dienes line is still unknown. For a long time, scientists though that boundary formation was solely due to production of bacteriocins, called proticines; however, boundaries formed even when no proticines were present (Senior, J Gen Micro 102:235).This phenomenon is of value in differentiating the two strains of Proteus for epidemiological purposes. The earlier entry below is not consistent with the current (2009) scientific understanding:[This line of inhibited growth results from the production of and sensitivity to different types of bacteriocins, namely, proticines, produced by different strains of Proteusspecies.If two strains were able to detect different proticines produced by a neighbor, there would be growth inhibition and the formation of a Dienes line. Alternatively, if no proticine difference were detected, the neighboring swarmer would be recognized as "self" and the swarms would interact.]
Proteus vulgaris typically appears as large, spreading colonies on Tryptic Soy Agar (TSA) media. The colonies have irregular edges and a characteristic swarming growth pattern. They are usually yellowish-brown in color and may have a slightly mottled appearance.
nutrients, particularly nitrogen and phosphorus. High levels of dissolved nutrients can lead to excessive algae growth, a phenomenon known as eutrophication, which can have negative impacts on water quality and ecosystem health. Controlling nutrient inputs can help manage algae growth in aquatic systems.
The biological protection of the brain when malnutrition temporarily affects body growth is known as the brain-sparing effect. This phenomenon ensures that the brain receives adequate nutrients to support its development and function, even when the rest of the body is undernourished.
