4Infection ControlInfection control is the term used to describe efforts to prevent the spread of disease and kill certain or all microbesChapter 2.2 Salon EcologyInfection Control
5Point 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?
6MicrobiologyABDoes photo A or B illustrate a healthy, infection-free, safe environment?Chapter 2.1 Salon EcologyMicrobiology
7MicrobiologyAPhoto A displays a healthy, infection-free, safe environment.Chapter 2.1 Salon EcologyMicrobiology
8Microbiology microbiology micro (small) bio (living) + ology (study) + The study of small organismsmicro (small)bio (living)+ology (study)+microbiologyA 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 EcologyMicrobiology
9BACTERIAMinute, 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.
10Bacteria Nonpathogenic Pathogenic Bacteria that do not produce disease Generally classified as two types:NonpathogenicPathogenicBacteria that do not produce diseaseBacteria that do produce diseaseChapter 2.1 Salon EcologyMicrobiology
11Bacteria Nonpathogenic Pathogenic Harmless Can be beneficial Many live on surface of skinSaprophytes live on dead matter70% of all bacteriaCause infection and diseaseDistinct shapesSome produce toxinsSpread easilyLive everywhereChapter 2.1 Salon EcologyMicrobiology
12Saprophyteslive on dead matterNon pathogenicJust to help you rememberSaprophytes are bacteria that have the sap knocked right out of them, so weak they cannot produce disease. There is no fight left in them
13Bacteria 1. Pathogenic Bacteria 2. 3. Appear in groups or singularly RoundCocciFound in boilsPus-formingBunchesStaphylococciCause strep throatPus-formingLong chainsStreptococciCause pneumoniaPairsDiplococci2.Most common form of bacterial cellsRodBacilli3.Causes syphilis,lyme disease,choleraSpiralSpirillaChapter 2.1 Salon EcologyMicrobiology
14Cocci 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..
15Staphylococci Pus-forming bacteria that grow in clusters like grapes; causeabscesses, pustules, and boilsStaphylococci form a bunch (like grapes) and "boil" up trouble by causing boils.the "staff" form a "bunch" and "boil" up trouble.
16Streptococci.Pus-forming bacteria arranged in curved lines resembling a string of beads;Causeinfections such as strep through and blood poisoning
17Spherical bacteria that grow in pairs and cause DiplococciSpherical bacteria that grow in pairs and causediseases such as pneumoniaThe word diplococci includes "diplo" which means two.draw 2 circles side by side and then draw them coughing.
18Bacilli 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
19Spirilla 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

21Key Terms Growth cycle of bacteria (Inactive) Growth cycle of bacteria (Active stage)Cocci (go back to yesterdays card)flagella or ciliaBacilli and spirilla ( go back to yesterdays cards)MitosisDaughter cells
22Growth of Bacteria Growth Cycle Active Stage Inactive Stage Reproduce and grow rapidlyRequire dark, damp, dirty places with foodDivide into two new cells (mitosis)Inactive StageNo growth occurs when conditions are unfavorableForm spores not harmed by disinfectants, cold or heatBecome active when conditions are favorableChapter 2.1 Salon EcologyMicrobiology
23Active growth Cocci Rarely show motility (self-movement); transmitted in air, dust, or in the substance in which they settle.
24MitosisThey then divide into two new cells. The division is called mitosisDaughter Cellsthe new cells are called daughter cells.
25Growth of Bacteria Movement of Bacteria Bacilli and spirilla use flagella(cilia) to propel themselvesChapter 2.1 Salon EcologyMicrobiology
26(Bacilli and Spirilla) flagella or cilia Motile and use slender, hairlike extensions known as flagella or ciliaFor locomotion A whip like motion of these hairs moves the bacteria in liquid.
27Growth of Bacteria Growth Cycle Active Stage Inactive Stage Reproduce and grow rapidlyRequire dark, damp, dirty places with foodDivide into two new cells (mitosis)Inactive StageNo growth occurs when conditions are unfavorableForm spores not harmed by disinfectants, cold or heatBecome active when conditions are favorableChapter 2.1 Salon EcologyMicrobiology
28Inactive 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
