Chapter 4 (and parts of 1) Study Guide Microbiology (Bauman 2007)
Objectives:
Once you have mastered these chapters, you should be able to:
 Name and describe the different types of microorganisms
 Describe and understand the scientific method
*Identify the two primary metric units used to measure microbes.
* List the units of the metric system in order, from meter to nanometer.
* Define microscopy.
* Explain the relevance of electromagnetic radiation to microscopy.
* Define empty magnification.
* List and explain two factors that determine resolving power.
* Discuss the relationship between contrast and staining in microscopy.
* Contrast simple and compound microscopes.
* Compare and contrast bright-field microscopy, dark-field microscopy, and phase
microscopy.
* Compare and contrast fluorescent and confocal microscopes.
* Contrast transmission electron microscopes with scanning electron microscopes in
terms of how they work, the images they produce, and the advantages of each.
* Describe two variations of probe microscopes.
* Explain the purpose of a smear, heat fixation, and chemical fixation in the
preparation of a specimen for microscopic viewing.
* Describe the use of acidic and basic dyes, mentioning ionic bonding and pH.
* Describe the simple, Gram, acid-fast, and endospore staining procedures; understand
the principles behind each and their common uses in bacteriology.
* Explain how stains for electron microscopy differ from those used in light
microscopy.
* Discuss the purposes of classification and identification of organisms.
* Discuss the difficulties in defining species of microorganisms.
* List the hierarchy of taxa from general to specific.
* Define binomial nomenclature
* List and describe the three domains proposed by Carl Woese.
* Name and describe the five procedures used by taxonomists to identify and classify
microorganisms.
 Describe and understand the serological methods we discussed in lecture.
