Rickettsia

Rickettsia is a gram-negative bacterium and is a group of G-prokaryotes that exclusively parasitize eukaryotic cells. It is a type of prokaryote that is intermediate between bacteria and viruses, but close to bacteria. Generally spherical or rod-shaped, it is an obligate intracellular parasite, mainly parasitic on arthropods. Some can be introduced into the human body through fleas, lice, ticks, and mites, such as typhus and trench fever.
