Name______________________________ Class __________________ Date ______________ Chapter 40 The Immune System and Disease Section 40–1 Infectious Disease (pages 1031–1035) This section describes the causes of disease and explains how infectious diseases are transmitted. Introduction (page 1031) 1. Any change, other than an injury, that disrupts the normal functions of the body, is a(an) disease . 2. What are three ways diseases can come about? Diseases can be inherited, caused by materials in the environment, or produced by agents. pathogens 3. Disease-causing agents are called The Germ Theory of Disease 4. State the germ theory of disease. . (pages 1031–1032) Infectious diseases are caused by microorganisms, or germs. 5. Circle the letter of each scientist whose work led to the germ theory of disease. a. Koch b. Steere c. Pasteur d. Burgdorfer 6. Is the following sentence true or false? Lyme disease is caused by bacteria. true 7. Circle the letter of the type of organism that spreads Lyme disease. a. mosquito b. deer tick © Pearson Education, Inc. All rights reserved. Koch’s Postulates c. deer fly d. horse fly (page 1032) 8. What are scientists trying to identify when they use Koch’s postulates? They are trying to identify the microorganism that causes a specific disease. 9. Number the steps in the flowchart below so they show how to apply Koch’s postulates. Pathogen identified 1 Pathogen injected into healthy lab mouse 3 Pathogen grown in pure culture Healthy mouse becomes sick Pathogen identified 2 4 5 Name______________________________ Agents of Disease Class __________________ Date ______________ (pages 1033–1034) 10. Is the following sentence true or false? Most of the bacteria and yeast that are found in false the body are harmful and cause disease. 11. List two ways that bacteria can produce illness. a. Breaking down tissues b. Releasing toxins Match each type of pathogen with a disease caused by that type. Type of Pathogen Disease d 12. Virus a. Athlete’s foot b 13. Bacterium b. Anthrax e 14.

Coughing, sneezing, or physical contact b. Contaminated water or food c. Infected animals 18. Animals that carry pathogens from person to person are called vectors . 19. Is the following sentence true or false? Thorough hand washing does not help prevent false the spread of many pathogens. Fighting Infectious Diseases (page 1035) 20. Compounds that kill bacteria without harming the cells of humans or animals are antibiotics . 21. Circle the letter of each sentence that is true about antibiotics. a. They work by interfering with the cellular processes of microorganisms. b. Many of them are produced by living organisms. c. They were first discovered in the 1940s. d. They are effective against viruses. 22. How do antiviral drugs fight viral diseases? Antiviral drugs inhibit the ability of viruses to invade cells and to multiply once inside cells. © Pearson Education, Inc. All rights reserved. called
