Have you ever lived with or visited someone that was a sloppy housekeeper?
Or Have you been the babysitter for children that refused to pick up their toys when requested?

A basic knowledge of microbiology is important in preventing the spread of disease through proper disinfection within the salon.
Why is the study of microbiology important to a cosmetologist?

9. BACTERIA
Minute, one-celled vegetable microorganisms found nearly everywhere.
Also known as germs or microbes.
:::Prominent in dust, dirt, refuse, and diseased tissues.
They can exist almost anywhere and can only be seen through a microscope.  

10. Bacteria Nonpathogenic Pathogenic Bacteria that do not produce disease
Generally classified as two types:
Nonpathogenic
Pathogenic
Bacteria that do not produce disease
Bacteria that do produce disease
Chapter 2.1 Salon Ecology
Microbiology

11. Bacteria Nonpathogenic Pathogenic Harmless Can be beneficial
Many live on surface of skin
Saprophytes live on dead matter
70% of all bacteria
Cause infection and disease
Distinct shapes
Some produce toxins
Spread easily
Live everywhere
Chapter 2.1 Salon Ecology
Microbiology

12. Saprophytes
live on dead matter
Non pathogenic
Just to help you remember
Saprophytes are bacteria that have the sap knocked right out of them, so weak they cannot produce disease. There is no fight left in them

13. Bacteria 1. Pathogenic Bacteria 2. 3. Appear in groups or singularly
Round
Cocci
Found in boils
Pus-forming
Bunches
Staphylococci
Cause strep throat
Pus-forming
Long chains
Streptococci
Cause pneumonia
Pairs
Diplococci 2.
Most common form of bacterial cells
Rod
Bacilli 3.
Causes syphilis,
lyme disease,
cholera
Spiral
Spirilla

14. Cocci Round-shaped that appear singly or in the following groups.
All the letters but i are rounded or circular. Cocci starts with a "c", as does circular. .

15. Staphylococci Pus-forming bacteria that grow in clusters like grapes;
cause
abscesses, pustules, and boils
Staphylococci form a bunch (like grapes) and "boil" up trouble by causing boils.
the "staff" form a "bunch" and "boil" up trouble.

16. Streptococci.
Pus-forming bacteria arranged in curved lines resembling a string of beads;
Cause
infections such as strep through and blood poisoning

17. Spherical bacteria that grow in pairs and cause
Diplococci
Spherical bacteria that grow in pairs and cause
diseases such as pneumonia
The word diplococci includes "diplo" which means two.
draw 2 circles side by side and then draw them coughing.

18. Bacilli Short rod-shaped bacteria
They are the most common and produce diseases such as tetanus, typhoid, tuberculosis, and diphtheria.
rod shaped and cause fevers, so the term "hot rod" Hot Rod

19. Spirilla Spiral or corkscrew-shaped bacteria.
They are subdivided into subgroups:
which causes syphilis (an STD) or lime disease.
corkscrew in shape, like a slinky or spiral c

21. Key Terms Growth cycle of bacteria (Inactive)
Growth cycle of bacteria (Active stage)
Cocci (go back to yesterdays card)
flagella or cilia
Bacilli and spirilla ( go back to yesterdays cards)
Mitosis
Daughter cells

22. Growth of Bacteria Growth Cycle Active Stage Inactive Stage
Reproduce and grow rapidly
Require dark, damp, dirty places with food
Divide into two new cells (mitosis)
Inactive Stage
No growth occurs when conditions are unfavorable
Form spores not harmed by disinfectants, cold or heat
Become active when conditions are favorable
Chapter 2.1 Salon Ecology
Microbiology

23. Active growth Cocci Rarely
show motility (self-movement); transmitted in air, dust, or in the substance in which they settle.

24. Mitosis
They then divide into two new cells. The division is called mitosis
Daughter Cells
the new cells are called daughter cells.

25. Growth of Bacteria Movement of Bacteria
Bacilli and spirilla use flagella
(cilia) to propel themselves
Chapter 2.1 Salon Ecology
Microbiology

26. (Bacilli and Spirilla) flagella or cilia
Motile and use slender, hairlike extensions known as flagella or cilia
For locomotion A whip like motion of these hairs moves the bacteria in liquid.

27. Growth of Bacteria Growth Cycle Active Stage Inactive Stage
Reproduce and grow rapidly
Require dark, damp, dirty places with food
Divide into two new cells (mitosis)
Inactive Stage
No growth occurs when conditions are unfavorable
Form spores not harmed by disinfectants, cold or heat
Become active when conditions are favorable
Chapter 2.1 Salon Ecology
Microbiology

28. Inactive or spore-forming Bacteria .
Such as anthrax and tetanus bacilli form spherical spores with tough outer coverings which are resistant to adverse conditions.
**Therefore, even bacteria in the inactive stage can ultimately be a Threat to the spread of disease or infection in the salon
