ANT220H5 Chapter Notes - Chapter 8: Bovine Spongiform Encephalopathy, Transmissible Spongiform Encephalopathy, Adaptive Immune System
Document Summary
Reading chapter 8: infectious diseases: pathogens, hosts, and evolutionary interplay. Infectious disease caused by microorgaims that make use of the resources of an individual to mature and reproduce and in doing so they provoke an immune response or otherwise disrupt the functioning of that individual. Parasites a group that makes use of the resources cause disease of other indivduals, usually of a different, larger bodied species. Individuals can provide a home for almost 90 trillion microbes. To be evolutionarily successful pathogens must be ale to infect a individual (host), go through matration phases, reproduce amd then get to another usceptible host before being destroyed by ht immune system or the host dies. Fundamental principles of establishing an infectious disease. Viruses among the simplest form of pathogen. Composed of dna, or rna surrounded by protein. Distinct geometric shapes commonly rodes and spheres. Obligate parasites can only replicate in a host.
