Rickettsiaceae
Rickettsiaceae (pronounced: rik-et-see-ay-see-ee) is a family of Gram-negative bacteria. This family of bacteria is named after Howard Taylor Ricketts, an American pathologist.
Etymology
The term "Rickettsiaceae" is derived from the name of Howard Taylor Ricketts, who was known for his work on tick-borne spotted fever. The suffix "-aceae" is a standard ending in biological taxonomy that denotes a family.
Description
Rickettsiaceae are small, rod-shaped or coccoid bacteria that are obligate intracellular parasites. They are typically transmitted to humans and other animals through the bite of an infected arthropod vector, such as ticks, fleas, and lice.
Genera
The family Rickettsiaceae includes the following genera:
Diseases
Members of the Rickettsiaceae family are responsible for a number of serious diseases in humans, including:
- Rocky Mountain spotted fever (caused by Rickettsia rickettsii)
- Typhus (caused by several species in the Rickettsia genus)
- Ehrlichiosis (caused by several species in the Ehrlichia genus)
- Anaplasmosis (caused by Anaplasma phagocytophilum)
Treatment
Treatment for diseases caused by Rickettsiaceae typically involves antibiotics, such as doxycycline and chloramphenicol.
