LECTURE 8 Notes Virology
Viruses are microbes that REQUIRE a host cell to replicate. By themselves they cannot
They border on the edge of living and non-living. Without a host cell, they cannot reproduce or
do anything. With a host cell, they c
LECTURE 2 NOTES (chapter 4)
What Is a Cell?
Cells are the fundamental units of life and carry out all the basic functions of living things.
What do the cells need?
1-Barrier from the environment (cell membrane)
2-Genetic infomations (DNA, Nu
Lecture 5 Notes (chapter 5)
Glycolysis, Fermentation, and Aerobic respiration are the metabolic processes used by most
microorganisms to capture energy.
-Glycolysis ( Embden-Meyerhof pathway) is the metabolic pathway used by most organisms
(both aerobes a

MICROBIOLOGY 20: UNIT 1
Introduction To Microbiology and Bacteria
-This unit aim to introduce Microbiology as a science and bacteria as a cell.
Note Outline for this session
-What is Microbiology?
The study of microbes, which a
Lecture 4 Notes(chapter 5)
Metabolism is the sum of all chemical processes carried out by living organism.
It includes anabolism and catabolism.
Anabolism is the reactions that require energy to synthesize complex molecules from simp
Lecture 6&7 (chapter 7) Microbial genetics
Gene (a specific segment of DNA) is the basic unit of heredity; it is a linear sequence of
nucleotides that form a functional unit of chromosome.
DNA structure is a:
Anti-parallel (5-> 3 and 3<- 5)
Lecture 11 Notes Bacteria Part 2
Local inflammation at the site of an infection produces calor because of the increase in blood
flow to the area.
Microbial infection is also characterized by a systemic (all over the body) increase in
Lecture 9 Notes Virology Part 2

Lecture 10 Notes Bacteria
Normal flora is the set of bacteria that normally live on (skin) or in (intestines) our body.
These bacteria does not overgrow and lives a very plain existence
The body keeps these bacteria in check.
Normal flora is the set of b

Cell Membrane (Plasma membrane, Cytoplasm membrane)
It is a living membrane that forms a barrier between the cell and its environment. Bacterial cell
membrane has a similar structure to other cell membranes ( Eukaryotic cell). I
