Caption: False-colour transmission electron micrograph (TEM) of Rickettsia rickettsii bacteria. The bacteria are seen in the cytoplasm of a Malpighian tube cell, a type of kidney cell, from the tick Dermacentor andersonii. This tick is the vector of rickettsia or Rocky Mountain spotted fever, a form of typhus. The disease is also known as spotted fever and tick fever. The two Rickettsia bacteria at upper right are undergoing the final stages of division, known as binary fission.
