Leeuwenhoek ANS: D Feedback A Pasteur made other important contributions to microbiology. B Koch made other important contributions to microbiology. C Lister made other important contributions to microbiology. D Leeuwenhoek first observed microbes and called them “animalcules.” REF: Discovery of Microorganisms and Infection Control Procedures, page 2 OBJ: 1 2. In which year were microbes first observed? A. 1667 B. 1880 C. 1956 D. 1975 ANS: A Feedback A Leeuwenhoek first observed microbes and called them “animalcules” in 1667. B This year is too recent. C This year is too recent. D This year is too recent. REF: Discovery of Microorganisms and Infection Control Procedures, page 2 OBJ: 1 3. The process of heating a fluid to 63o C for 30 minutes to kill bacteria is best known as: A. sterilization. B. disinfection. C. pasteurization. D. decontamination. ANS: C Feedback A Sterilization uses higher temperatures. B Disinfection usually is related to the use of germicides on inanimate surfaces. C Pasteurization was first used to kill microbes in milk and other liquids and is still used today. D Decontamination is a general term for the removal or killing of microbes by a variety of methods. REF: Discovery of Microorganisms and Infection Control Procedures, page 3 OBJ: 2 4. When was the “Golden Age of Microbiology?” A. Mid to late 1600s B. Mid to late 1700s C. Mid to late 1800s D. Mid to late 1900s ANS: C Feedback A This period was too early. B This period was too early. C This was the time when many new discoveries in microbiology were being made. D This period was too late. REF: Discovery of Microorganisms and Infection Control Procedures, page 2 OBJ: 1 5. What microbes are used to make vinegar, vitamins, drain cleaners, enzymes, and other products? A. Fungi B. Viruses C. Protozoa D. Bacteria ANS: D Feedback A Fungi can make antibiotics but not these products. B Viruses grow inside living cells and do not make such products. C Protozoa are not very efficient in making such products. D Bacteria make these and other products when they are grown in large vats. REF: Important Activities of Microorganisms, page 3 OBJ: 3 6. Which microbes are used to make pickles out of cucumbers? A. Bacteria or fungi B. Fungi or viruses C. Viruses or yeasts D. Bacteria or viruses ANS: A Feedback A These microbes make certain extracellular products that change cucumbers into pickles. B Viruses do not produce products that affect cucumbers. C Viruses do not produce products that affect cucumbers. D Viruses do not produce products that affect cucumbers. REF: Important Activities of Microorganisms, page 4 OBJ: 3 7. What microbe is used to make bread dough rise? A. Bacteria B. Yeasts C. Viruses D. Protozoa ANS: B Feedback A Bacteria do not produce enough carbon dioxide (CO2) to make the dough rise. B Yeasts metabolize carbohydrates to produce the gas bubbles of CO2; this process causes the dough to rise. C Viruses only grow inside of living cells and do not have a regular metabolism. D Protozoa do not produce enough carbon dioxide (CO2) to make the dough rise. REF: Important Activities of Microorganisms, page 4 OBJ: 3 COMPLETION 1. Louie Pasteur and John Tyndall first recognized the use of _____ to destroy bacteria and resistant spores. ANS: heat REF: Discovery of Microorganisms and Infection Control Procedures, page 3 OBJ: 2 2. In 1915 it was discovered that bacteria can be infected with viruses called _____. ANS: bacteriophages REF: Discovery of Microorganisms and Infection Control Procedures, page 3 OBJ: 1 TRUE/FALSE 1. The disease of smallpox was involved in the discovery of immunizations in the 1790s by Edward Jenner. ANS: T Edward Jenner is credited with recognizing the concept of immunization when he realized in the 1790s that milkmaids who caught cowpox, a mild disease, were protected from the more serious disease of smallpox. REF: Discovery of Microorganisms and Infection Control Procedures, page 3 OBJ: 1 Chapter 2: Characteristics of Microorganisms Test Bank MULTIPLE CHOICE 1. Viruses multiply: A. in the absence of nutrients. B. only when they are inside of living cells. C. when they are outside of living cells. D. only when the temperature is below 7°C. ANS: B Feedback A Nothing can grow in the absence of nutrients. B Viruses need the nutrients and metabolic machinery of living cells to multiply. C Viruses cannot obtain their nutrients from the environment. D Only the special bacteria called psychrophiles can grow at these low temperatures. REF: Life Cycle, page 15 OBJ: 5 2.
