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:
“What if there are not only two nostrils, two eyes, two lobes, and so forth, but two psyches as well, and they are separately equipped? They go through life like Siamese twins inside one person.... They can be just a little different, like identical twins, or they can be vastly different, like good and evil.”
—Norman Mailer (b. 1923)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
