PBS 3.1.2

Goals:

  • Summarize how infectious diseases can be spread, treated, and prevented

  • Describe the characteristics of the six categories of infectious agents

  • Evaluate evidence to solve a problem

  • Agents of Disease - types of organisms that cause disease

  • Inherited - passed down genetically

  • Infectious - contracted/caught

  • Infection - disease causing organism invades and begins growing within another organism - host

  • Disease - invasion and growth of pathogen impairs bodily functions

  • Pathogen - infectious organisms that cause disease

  • Microbes - infectious agents that can only be seen under a microscope

  • Types of infectious agents: prions, viruses, bacteria, protists, fungi, and helminths

  • Prions - non-living, submicroscopic proteins

  • Viruses - non-living microscopic agent with outer protein shell (capsid) and DNA or RNA

  • Bacteria - living, microscopic, unicellular, prokaryotic organisms

  • Protists - living, microscopic, single-celled eukaryotic, animal-like organisms

  • Fungi - living, multicellular, eukaryotic organisms (both microscopic and macroscopic varieties exist)

  • Helminths - living, multicellular, eukaryotic worms (both microscopic and macroscopic varieties exist)

  • Electroencephalogram (EEG) - analyzes brain waves

  • Normal Flora/Microbiota - live on us
