4. Koch's postulates were developed primarily to
• classify viruses
■ link a specific microbe with a specific disease
• measure bacterial growth rate

• pasteurization
6. Joseph Lister applied germ theory to surgery by promoting
■ antiseptic procedures

• microbes arise spontaneously
• viruses are always harmless
8. The Golden Age of Microbiology is associated with major advances in
■ microbial identification and disease causation

• ecology without microscopy
9. Which scientist is most closely associated with developing vaccines for anthrax and rabies?
■ Louis Pasteur
• Edward Jenner
• Alexander Fleming
• Hans Christian Gram
