Introduction to Microbiology -Mooc CS1161

The microbes that usually live on or in a person are collectively referred to as:

• germs

• indigenous microbiota

• nonpathogens

• oppurtunistic pathogens

The study of algae is called:

• algaelogy

• botany

• mycology

• phycology

Which of the following statements is true?

• Koch developed a rabies vaccine

• Microbes are ubiquitous

• Most microbes are harmful to humans

• Pasteur conducted experiments that

  proved the theory of abiogenesis

Which of the following is not a reason for microorganisms being useful in research?

• Microbes have high reproduction rates.

• Microbes are easily controlled.

• Microbes have relatively simple structures.

• Microbes make it easier to prove the statistical significance

  of an experiment because of their ease and cost

  effectiveness resulting from their large numbers.

The epidemic that infected Europe, North Africa, and the Middle East and killed tens of millions was known as the Black Death. The disease was caused by:

• Smallpox

• Anthrax

• Bubonic plaque

• Swine flu

The event that triggered the development and establishment of microbiology as a science is the:

• Spontaneous generation

• Germ theory of disease

• Vaccinations

• Development of the microscope

Which scientist first disproved spontaneous generation by showing that maggots only appear on decaying meat that has been exposed to flies?

• Lister

• Pasteur

• Hooke

• Redi

The germ theory of disease states that:

• Microorganisms that invade other organisms can cause

  disease in those organisms

• Microorganisms can spontaneously arise in debilitated

  hosts

• Microorganisms do not cause infectious diseases

• Not all microorganisms are harmful

Put Koch’s postulates in order:

(a) The disease organism must be isolated in pure culture.

(b) The disease organism must be recovered from the inoculated

animal.

(c) The specific causative agent must be found in every case

of the disease.

(d) Inoculation of a sample of the culture into a healthy, susceptible

animal must produce the same disease.

Which of the following individuals is considered to be the “Father of Microbiology?”

• Anton van Leeuwenhoek

• Louis Pasteur

• Robert Koch

• Rudolf Virchow
