1 Principles of Infection Infection Control

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 1 Microbiology Bacteria Harmful Growth Movement Review Chapter 2.1 Salon Ecology Microbiology Non Harmful

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

5 Point to think about! 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?

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

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

8 Microbiology Chapter 2.1 Salon Ecology Microbiology The study of small organisms micro (small) bio (living) ology (study) + + microbiology Why is the study of microbiology important to a cosmetologist? A basic knowledge of microbiology is important in preventing the spread of disease through proper disinfection within the salon.

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 Chapter 2.1 Salon Ecology Microbiology Generally classified as two types: NonpathogenicPathogenic Bacteria that do not produce disease Bacteria that do produce disease

11 Bacteria NonpathogenicPathogenic 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 Chapter 2.1 Salon Ecology Microbiology Cause strep throat Pus-forming Long chainsStreptococci Found in boils Pus-forming BunchesStaphylococci Cause pneumoniaPairsDiplococci Pathogenic Bacteria Appear in groups or singularly RoundCocci Bacteria Most common form of bacterial cells RodBacilli 1. Causes syphilis, lyme disease, cholera Spiral Spirilla

14 1.Cocci 1.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 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 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 2.1 Salon Ecology Microbiology Growth Cycle

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

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 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 2.1 Salon Ecology Microbiology Growth Cycle

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
