If an affected individual is treated with appropriate antibiotic therapy within the first three to five days of illness, the fever usually subsides within two to three days. However, for those who are severely ill, the fever may take longer to subside on appropriate antibiotic therapy.

Can Rickettsia cause thrombocytopenia?

Injured endothelium may become denuded, exposing thrombogenic subendothelium. The endothelial cell is the primary target in rickettsial infections. Platelet adhesion to injured endothelium is the major mechanism of thrombocytopenia in the spotted fever group of diseases (Rao et al 1988).

What are the long-term side effects of Rocky Mountain spotted fever?

Rocky Mountain spotted fever long-term effects

  • inflammation of the brain, known as meningitis, leading to seizures and coma.

Does Rickettsia cause Lyme disease?

That’s why these tick-borne conditions are called rickettsial diseases. But not all diseases that ticks carry are rickettsial. For instance, Lyme disease is caused by a different bacteria called Borrelia burgdorferi.

Is the presence of Rickettsiae a chronic illness?

It is not known whether the presence of rickettsiae is causally related to the patients’ chronic illnesses, or reactivation of a latent rickettsial infection. Chronic illness can be frustrating for patient and doctor alike.

What are the symptoms of a tick borne disease?

A third tick-borne disease, Ehrlichosis, is caused by the Ehrlica chaffeenis organism, a bacteria that lives within cells. While some people will experience no symptoms, others will experience chills, fever, flu-like symptoms, weakness, muscle pains, chronic fatigue, and headaches.

How is rickettsiae disease transmitted from tick to human?

Rickettsiae are small obligate intracellular bacteria usually transmitted to a human via the bite of an arthropod, often a tick. Rickettsial disease usually has an acute onset and has major symptoms of headache, rash, fever, myalgia, arthralgia and fatigue. 25
