From Wikipedia, the free encyclopedia
Rickettsia rickettsii is a gram-negative intracellular alpha proteobacteria. This bacteria is one of the four groups that result from a rickettsial infection that include the spotted fever group, the typhus group, the ancestral group, and the transitional group[1]. As a part of the spotted fever group, Rickettsia rickettsii is considered one of the most pathogenic of its family[2]. R. rickettsii is the causative agent for Rocky Mountain Spotted Fever, which is transferred to its host via a tick bite. It is most common in the Americas[3], and was discovered by a professor at the University of Chicago in 1902[4].
This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |
