BIOL 2335 Lecture Notes - Lecture 12: Parasitism, Ebola Virus Disease
Document Summary
Reproduction use of host resources to create new parasites: efficient use of host resources and machinery, host defense: immune system, 2. Transmission depends on rate at which new hosts are encountered: alter host behavior transport by host to environment, host defense: detection and avoidance of infected individuals or environments, 3. Infection depends on probability invading new host: tricks immune systems/ defenses, host defense: recognition of non- self. Determinants of parasite success: parasite growth rate (r) is function of reproduction and infectivity/ transmission, reproduction can kill hosts infectivity/ transmission require new and living hosts. Interaction between reproduction and infectivity are crucial for understanding host parasite interactions. Basic properties of parasites necessary for their success and the corresponding responses to host organism. Which of following statements about parasite reproduction is true: can evoke host defenses.
