3 Classifications of Pathogenic Bacteria Cocci- round shaped, appear singly or in groupsStaphylococci-pus- forming grow in clusters (abscesses, pustules and boils)Streptococci-pus-forming, grow in chains(strep throat, blood poisoning)Diplococci-grow in pairs (pneumonia
4 Classifications of Pathogenic Bacteria Bacilli- short, rod-shaped bacteria (lockjaw, typhoid fever and tuberculosis)Spirilla- spiral or corkscrew shaped (syphillis or Lyme disease
5 Movement of BacteriaCocci-transmitted in air, dust or within substance on which they settle.Bacilli and spirilla are motile and have slender, hair-like extensions known as flagella or cilia for locomotion.
6 Growth and Reproduction Active Stage-grow and reproduce-warm, dark, damp places-sufficient food availableDivide into two new cells – mitosisInactive (spore forming stage)-form spherical spores with tough outer covering for protection-cannot be harmed by disinfectantsWhen conditions are favorable they grow and reproduce.
13 How Pathogens Enter the Body Break in the skinMouthNoseEye or earsUnprotected sex
14 Principles of Prevention Decontamination-removal of pathogens from tools and surfaces by physical or chemical means.3 levels of decontamination
15 Sterilization Highest level of decontamination Completely destroys every organism.Methods include steam autoclave and dry heat
16 DisinfectionControls microorganisms on nonporous surfaces. Does not kill bacterial spores.
17 DisinfectantsDisinfectants chemical agents used to destroy most bacteria and viruses.Disinfectants are not for use on human skin, hair or nails.
18 DisinfectantsQuats-quaternary ammonium compounds-–non-toxic, fast actingPhenols-not recommended for rubber and plastic itemsAlcohol -70% (ethyl, 99% for IsopropylBleach
19 Disinfecting Implements Pre-clean implements & tools.Rinse thoroughlyPut on gloves and safety gogglesMix solution according to manufacturers directionsImmerse tools or implements required timeRemove implementsRinse and dry thoroughlyStore in clean, closed dry disinfected container.
20 Requirement For ALL Students concerning dirty implements. Every student must have at their station the following:Zip lock baggie marked “pre-sanitized implements” for their clean combs and brushes.Zip lock baggie marked “soiled implements”.Make sure each student cleans dirty combs and brushed with hot water and soap, the place in wet sanitizer.Station inspections will be performed regularly without prior notice.
21 Blood Spill Disinfection Stop service and clean injured area.Use gloves or finger guardApply antisepticCover injury with band-aid or other dressingClean workstationDiscard contaminated objectsDouble-bag, use biohazard stickerRemove gloves, wash hands with soap and waterDisinfect contaminated items by full immersion in EPA-hospital grade disinfectant
22 Sanitation“To significantly reduce the number of pathogens or disease producing organisms found on a surface”Proper washing of hands before and after each client.
23 Your Professional Responsibility Protect you client’s health and safety as well as your own.Never take shortcuts with sanitation and disinfection.Follow the rules of safety and sanitation always.
24 SANITATION IS EVERYONE’S RESPONSIBILITY THE BUCK STOPS HERE!!INSTRUCTORS, STUDENTS, STAFF AND ADMINISTRATORS
