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

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?

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

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

Microbiology microbiology micro (small) bio (living) + ology (study) + 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 2.1 Salon Ecology Microbiology

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.  

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

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

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

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 Chapter 2.1 Salon Ecology Microbiology

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.   .

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.

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

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.  

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

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

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

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

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

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

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

(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.

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
