Introduction (LSI Quadrant I):
SAY: In order to understand the importance of sanitation, disinfections, and sterilization you must have a basic understanding of bacteriology. Your knowledge of bacteriology will help you to comprehend the relationship between bacteria and disease. ACTIVITY: Have students to individually brainstorm ideas/thoughts related to lesson content and have them write one down and be ready to share their idea/thought at the end of the lesson.

[Prompt thought: Think of how bacteria can be spread or found. Prompt example: Workers not washing hands in a restaurant.]
Outline (LSI Quadrant II):
I. Define terms associated with the lesson.
A. Bacteriology: The science that deals with the study of microorganisms called bacteria. B. Bacteria: minute, one-celled vegetable microorganisms found nearly everywhere; dust, dirt, refuse, and diseased tissue.

1. Also known as germs.
2. Can only be seen through the aid of a microscope; 1500 can cover the head of a pin. II. Identify Types of Bacteria (show transparency LP3/T1)
A. Nonpathogenic and Pathogenic
B. Nonpathogenic
1. Helpful or harmless.
2. Perform useful functions; decompose refuse and improve soil fertility. C. Saprophytes are a type of nonpathogenic bacteria that live on dead matter and do not produce disease.
D. Pathogenic
1. Harmful.
2. Disease producing.
3. Invade plant or animal tissue.
4. Parasites are a type of pathogenic bacteria that require living matter for growth. III. Explain Pathogenic Classifications
A. Pathogenic bacteria are identified by distinct shapes.
*Use the following story to help explain classifications:
▪ There once lived a guy called Tyrone Cocci
▪ He has a round shape
▪ He likes to hang around singly or in groups
▪ He is not very active
▪ He is most comfortable when he is hanging out in the air or dirt ▪ Tyrone Cocci had three wives: Staphylococci, Streptococci, and Diplococci ▪

Mrs. Staphylococci; Tyrone Cocci did not like her because of these reasons; She is pus-forming
She hangs out in bunches or clusters
She has a lot of abscesses, pustules, and boils

Mrs. Diplococcic; Tyrone Cocci did not like her because of these reasons; She hangs out in...
