- Differentiate between a definitive host and an intermediate host.In terms of geographical distribution, are parasitic flagellates (e.g., Trypanosoma spp., Leishmania tropica, Giardia lamblia, Trichomonas) cosmopolitan or localized? Explain Discuss the relationship between vector distribution of some parasites and their vectors, if any? Do they exhibit vector specificity?Which type of interaction is least harmful to the host?
- What is obligate parasite?Explain how within-host growth of parasites can functionally link virulence and transmission, and how those results in selection favoring an intermediate level of virulence. What evidence did Fraser et al. 2007 provide in support of the trade-off hypothesis.How does host specificity (host range) impact a parasite's likelihood of causing host extinction?
