Rickettsia treatment and symptoms

we will learn here Rickettsia treatment and symptoms so you need to focus well.

Rickettsia is a genus of nonmotile, gram-negative, nonspore-forming,
highly pleomorphic bacteria that can be present as cocci
 (0.1 μm in diameter), rods (1–4 μm long), or thread-like (10 μm long). The term rickettsia, named after Howard Taylor Ricketts, is often used interchangeably
 for any member of the Rickettsiales. Being obligate
intracellular parasites, the Rickettsia survival depends
on entry, growth, and replication within the cytoplasm f eukaryotic
 host cells (typically endothelial cells).[8] Rickettsia cannot live in artificial nutrient environments and is grown either in tissue or embryo cultures; typically, chicken embryos are used: a method developed by Ernest William Goodpasture and his colleagues at Vanderbilt University in the early 1930s.

Rickettsia species are transmitted by numerous types of arthropod,
 including chigger, ticks, fleas, and lice, and are associated with both human and plant disease. Most notably, Rickettsia species are the pathogen responsible for: typhus,
 rickettsialpox, Boutonneuse fever, African tick bite fever, Rocky Mountain
spotted fever, Flinders Island spotted fever and Queensland tick typhus
 (Australian tick typhus).[9] Despite the similar name, Rickettsia bacteria do not cause rickets, which is a result of vitamin D deficiency. The majority of Rickettsia bacteria are susceptible to antibiotics of the tetracycline group.
