Many factors contribute to this variability and included among them may be parasite size, induced injury, reproductive potential, nutritional requirements (including metabolites or toxins produced), niche selection (often influenced by individual life cycles and migration patterns through the host), and last, but not the least, immunologic consequences of infection.
