Activity 5.1.2: Infectious Disease Agents Introduction In the last activity, you were presented with an incomplete piece of Anna’s medical history documenting an unknown illness. In this activity you will begin your detective work by exploring the different types of pathogens as well as examining specific examples of each type in order to identify what is plaguing Anna. There are six major types of infectious agents: bacteria, viruses, fungi, protozoa, helminthes, and prions. You will investigate a variety of diseases caused by infectious agents and use this information to determine the tests you will need to perform in the subsequent activities to fill in the missing pieces from Anna’s medical history. Equipment Computer with Internet access Laboratory journal Activity 5.1.2 Disease Cards Resource Sheet or Disease Cards PowerPoint Activity 5.1.1 Medical History Resource Sheet PBS Course File Procedure 1. Create the following graphic organizer in your laboratory journal. Type of Infectious Agent Disease Examples Modes of Transmission Does the Agent Require a Host for Reproduction? How the Agent is Treated Bacteria Viruses Fungus Protozoa Helminthes Prions © 2013 Project Lead The Way, Inc. Principles of Biomedical Science Activity 5.1.2 Infectious Disease Agents – Page 1 2. Work with a partner and read through each Disease Card (either on the resource sheet or on the presentation). As you read, highlight key information on each disease. 3. Note any similarities between the diseases caused by the same type of infectious agent. Based on this, fill in your graphic organizer. 4. If necessary, use the Internet to research the six types of infectious agents and fill in any missing information in your graphic organizer. 5. Answer the Conclusion questions. Conclusion 1. Why is it useful for epidemiologists, scientists who study disease, to categorize diseases based on different factors, such as modes of transmission? 2. How would the infection simulation you performed in the last activity have been different if you had performed it for syphilis? What about for malaria? (Hint: Think about the transmission of these diseases.) 3. Using your completed graphic organizer, what can be done to prevent the transmission of each infectious agent? Bacteria: Viruses: Fungus: Protozoa: Helminthes: Prions: 4. What should your next steps be as medical detectives in order to fill in the missing pieces of Anna’s medical history?
