Mechanism of Illness
Humans contract the disease after a bite by an infected tick of the species Amblyomma americanum.
Those with an underlying immunodeficiency (such as HIV) appear to be at greater risk of contracting the disease. Compared to HME, ewingii ehrlichiosis has a decreased incidence of complications.
Like Anaplasma phagocytophilum, the causative agent of human granulocytic ehrlichiosis, Ehrlichia ewingii infects neutrophils. Infection with E. ewingii may delay neutrophil apoptosis.

Famous quotes containing the words mechanism of, mechanism and/or illness:
“The two elements the traveler first captures in the big city are extrahuman architecture and furious rhythm. Geometry and anguish. At first glance, the rhythm may be confused with gaiety, but when you look more closely at the mechanism of social life and the painful slavery of both men and machines, you see that it is nothing but a kind of typical, empty anguish that makes even crime and gangs forgivable means of escape.”
—Federico García Lorca (1898–1936)
“Life is an offensive, directed against the repetitious mechanism of the Universe.”
—Alfred North Whitehead (1861–1947)
“The fact that illness is associated with the poor—who are, from the perspective of the privileged, aliens in one’s midst—reinforces the association of illness with the foreign: with an exotic, often primitive place.”
—Susan Sontag (b. 1933)
