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.
