Pathogen Life Cycle
The life cycle of Rickettsia rickettsii is considered to be a complex one. Survival is dependent on both an invertebrate vector, (the hard tick- Family Ixodidae) and a vertebrate host (including mice, dogs, rabbits). Humans are considered to be accidental vectors and are not essential in the rickettsial cycle. In addition, a sequence of events occur between both hosts in the successful transmission of rickettsial disease.
Rickettsia rickettsii mostly affects canines and humans.

Famous quotes containing the words life and/or cycle:
“The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?”
—Edgar Allan Poe (1809–1845)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
