Chap. 9 & 10 Microbial Genetics (DNA Replication & Protein Synthesis), Recombinant DNA,
I. THE BASIS OF HEREDITY
All information necessary for life is stored in an organisms chromosomes, which are made up of
DNA (exception: some viruse
Chapter 11 - Controlling Microbes (Sterilization & Disinfection)
Some Important Terms Defined:
sterilization - treatment to destroy all microbial life (even destroys bacterial endospores and
fungal spores); there are no degrees of sterility!
Chapter 8 - Metabolism of Microbes
I. A Model for Metabolism (using E. coli as an example)
What is metabolism? All the biochemical reactions that take place in a cell.
The Model: Metabolism leading to the synthesis of a new microbial cell has 3 requiremen
Chap. 7 - Microbial Growth
The term microbial growth refers to the growth of a population (or an increase in the number of
cells), not to an increase in the size of the individual cell. Cell division leads to the growth of
cells in the population.
Chap. 6 - The Viruses
virus means poison; someone once called them "a piece of bad news wrapped in a protein;"
obligate intracellular parasites (can reproduce/replicate only inside a host cell)
not cells; debate over whether or no

Chapter 18-23 - Eukaryotic Organisms [Fungi, Protozoans, Helminths, & Arthropod Vectors]
Features that distinguish protozoal & helminthic infections :
1.) More important in tropical cou
Chapter 4 Characteristics of Prokaryotic & Eukaryotic Cells
All cells have:
1. Cell or plasma membrane (separates the cell from the outer environment)
2. Genetic material (DNA)
TWO GENERAL TYPES OF CELLS:
A. Prokaryotic ("before nucleus")
Chp. 3 Microscopy and Staining
Microscopy is the technology of making very small things visible to the human eye. Most
microbes are so small that they are measured in micrometers or nanometers. A typical bacterial
cell is about 1 um while a
CHAPTER 2 INTRODUCTORY CHEMISTRY & BIOCHEMISTRY
Why is it necessary to study chemistry? Living things are made of matter (anything that
occupies space & has mass) & matter follows the laws of chemistry. Even the characteristics we
Chap. 1 Scope and History of Microbiology
Why Study Microbiology?
1. Impact on Human Health
2. Balance of Nature - food source, play a role in decomposition, help other animals digest
grass (cattle, sheep, termites).
3. Environmental provide safe drinking
