Rickettsia rickettsii is native to the New World and causes the malady known as Rocky Mountain spotted fever (RMSF). RMSF is transmitted by the bite of an infected tick while feeding on warmblooded animals, including humans. Man is an accidental host in the rickettsia-tick life cycle and is not required to maintain the rickettsiae in nature.
Yersinia Pestis is a bacterium that undergoes reproduction through fission, an asexual form of reproduction that occurs in approximately 1.25 hours.
males and usually kids under 15 will be affected by it most.
Rickettsia rickettsii is the cause of Rocky Mountain spotted fever (RMSF) and is the prototype bacterium in the spotted fever group of rickettsiae. Rickettsia rickettsii is found in the Americas and is transmitted to humans through the bite of infected ticks. The bacterium infects human vascular endothelial cells, producing an inflammatory response. The pathogenesis of RMSF is discussed in some detail below.
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.

Rickettsia rickettsii is a virus strain that causes the malady known as Rocky Mountain spotted fever. It is circular to ovoid in shape and stains well in Indigotine dye, showing no other visible internal features.
Rickettsia rickettsii, which is a type of bacteria carried by ticks.
Rocky Mountain spotted fever is caused by the bacterium Rickettsia rickettsii.
The bacterial culprit in RMSF is called Rickettsia rickettsii. It causes no illness in the tick carrying it, and can be passed on to the tick's offspring.
The pathogen is Rickettsia rickettsii. Vectors for this bacteria include the American dog tick and the Rocky Mountain wood tick.
Rickettsia rickettsii is the bacteria responsible for Rocky Mountain Spotted Fever and is most commonly caused by a tick bite.
Rocky Mountain spotted fever is a tick bourne illness. It travels through tick bites and is actually one of the more severe tick bourne diseases.It can also be spread from people in large crowds or people who aren't clean.
Rocky Mountain Spotted Fever is a tickborne disease cause by a bacteria, Rickettsia Rickettsii. It enters the bloodstream through a break in the skin allowing the parasites saliva, crushed tissue, or fluids from it's feces to infect the body.
