Orientalism

What are some of the ways in which the novel Dracula (and the Count himself) represent a Western fear of “reverse colonization” or “infection” by the “exotic” East? How does the novel try to define the West in a positive light and the East as "backwards"? You should include an appropriate quotation from Stephen Arata's article, "The Occidental Tourist: Dracula and the Anxiety of Reverse Colonization."
