These diseases can be serious and require prompt medical treatment.

When the body is exposed to epidemic typhus, caused by the bacterium Rickettsia prowazekii and transmitted by lice, it typically triggers an immune response characterized by fever, chills, headache, and muscle aches. The body may also develop a rash, which usually starts on the torso and spreads. As the infection progresses, it can lead to more severe complications, including neurological issues and organ failure if not treated promptly. Overall, the body's reaction involves mobilizing immune defenses to combat the infection, but severe cases can result in significant morbidity.
Obligate Intracellular Parasites?
Gram negative rods or coccobacilli 2) Unable to reproduce outside of a host cell. 3) Lost ability to synthesize needed for extracellular growth. 4) Transmitted when a blood-sucking arthropod (tick or louse) takes a blood meal from a human. 5) Rickettsia rickettsii - Rocky Mountain Spotted Fever 6) Rickettsia prowazekii - epidemic typhus 7) Coxiella burnetii - Q fever 8) Survives outside host & does not require an arthropod for transmission.
