Infection Control

1. Infection Control Principles of Infection

2. Key Terms • Infection Control • Microbiology • BACTERIA • 1. Nonpathogenic(Bacteria) • 2. Pathogenic(Bacteria) • Saprophytes • CLASSIFICATIONS OF PATHOGENIC BACTERIA. • Cocci • Staphylococci • Streptococci • Diplococci • Bacilli • Spirilla

3. Infection Control Infection control is the term used to describe efforts to prevent the spread of disease and kill certain or all microbes Chapter 2.2Salon Ecology Infection Control

4. Point to think about! • Have you ever lived with or visited someone that was a sloppy housekeeper? • OrHave you been the babysitter for children that refused to pick up their toys when requested?

5. A B Microbiology Does photo A or B illustrate a healthy, infection-free, safe environment? Chapter 2.1Salon Ecology Microbiology

6. A Microbiology Photo A displays a healthy, infection-free, safe environment. Chapter 2.1Salon Ecology Microbiology

7. Microbiology The study of small organisms micro (small) + bio (living) ology (study) + microbiology 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? Chapter 2.1Salon Ecology Microbiology

8. 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.  

9. Bacteria Generally classified as two types: Nonpathogenic Pathogenic Bacteria that donotproduce disease Bacteria that doproduce disease Chapter 2.1Salon Ecology Microbiology

10. 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 2.1Salon Ecology Microbiology

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

12. Cocci Round Appear in groups or singularly Staphylococci Bunches Found in boils Pus-forming Streptococci Long chains Cause strep throat Pus-forming Diplococci Pairs Cause pneumonia Most common form of bacterial cells Bacilli Rod Spirilla Causes syphilis, lyme disease, cholera Spiral Bacteria Pathogenic Bacteria Chapter 2.1Salon Ecology Microbiology

13. 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. • .

14. 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.

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

16. 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.

17. 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

18. Spirilla • Spiralor • 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

19. Microbiology Self-Check Identify the type of pathogenic bacteria Pus-forming cells that form bunches; found in boils Grow in pairs and can cause pneumonia 1. _______ Diplococci 4. ________ Staphylococci Spiral-shaped cells that cause syphilis, and lyme disease Most common form of bacterial cells 5. ________ Spirilla 2. _______ Bacilli Pus-forming cells that form long chains; cause strep throat 3. ________ Streptococci Chapter 2.1Salon Ecology Microbiology

20. 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

21. Growth of Bacteria Growth Cycle • Active 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 2.1Salon Ecology Microbiology

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

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

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

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

26. Growth of Bacteria Growth Cycle • Active 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 2.1Salon Ecology Microbiology

27. 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

28. Microbiology Self-Check Identify the type of pathogenic bacteria Pus-forming cells that form bunches; found in boils Grow in pairs and can cause pneumonia 1. _______ Diplococci 4. ________ Staphylococci Spiral-shaped cells that cause syphilis, and lyme disease Most common form of bacterial cells 5. ________ Spirilla 2. _______ Bacilli Pus-forming cells that form long chains; cause strep throat 3. ________ Streptococci Chapter 2.1Salon Ecology Microbiology

29. Microbiology Self-Check What’s your answer? A. Nonpathogenic or B. Pathogenic • 70% of all bacteria • Produce disease • Include saprophytes • Harmless A B A A Chapter 2.1Salon Ecology Microbiology

30. Microbiology Self-Check On a sheet of paper numbered 1-4 answer the following questions. What’s your answer? A. Active Bacteria or B. Inactive Bacteria • Grow rapidly • Exhibit mitosis • Form spores • Stop growing Chapter 2.1Salon Ecology Microbiology
