antiseptics
- chemical germicides formulated for use on skin
- registered and regulated by the Food and Drug Administration (FDA)
aseptic procedures
a process of properly handling sterilized and disinfected equipment and supplies to reduce contamination
asymptomatic
showing no symptoms or signs of infection
autoclave
a device for sterilization by steam under pressure
bacilli
- short rod-shaped bacteria
- they are the most common bacteria and produce diseases such as tetanus (lockjaw), typhoid fever, tuberculosis, and diphtheria
bacteria
(singular : bacterium)
- one-celled microorganisms that have both plant and animal characteristics
- some are harmful
- some are harmless
bactericidal
capable of destroying bacteria
binary fission
the division of bacteria cells into two new cells called daughter cells
bioburden
the number of viable organisms in or on an object or surface or the organic material on a surface or object decontamination or sterilization
bloodborne pathogens
disease-causing microorganisms carried in the body by blood or body fluids, such as hepatitis and HIV
body substance isolation
- abbreviated BSI
- a system of precautions developed by a Seattle hospital in 1987 to prevent contact with bodily substances and fluids by using protective apparel to prevent the spread of communicable disease
chelating soaps
- aka. chelating detergents
- detergents that break down stubborn films and remove the residue of products such as scrubs, salts, and masks
clean
- aka. cleaning
- a mechanical process (scrubbing) using soap and water or detergent and water to remove all visible dirt, debris, and many disease-causing germs
- cleaning also removes invisible debris that interferes with disinfection
cocci
- round-shaped bacteria that appear singly (alone) or in groups
- the three type of cocci are staphylococci, streptococci, and diplococci
contagious disease
- aka. communicable disease
- a disease that is spread from one person to another person
- some of the more contagious diseases are the common cold, ringworm, conjunctivitis (pinkeye), viral infections, and natural nail or toe and foot infections
contamination
- the presence, or the reasonably anticipated presence, or blood or other potentially infectious materials on an item’s surface or visible debris or residues such as dust, hair, and skin
cross-contamination
contamination that occurs when you touch one object and then transfer the contents of that object to another, such as touching skin, then touching a product without washing your hands
decontamination
the removal of blood or other potentially infectious materials on an item’s surface and the removal of viable debris or residue such as dust, hair, and skin
dermatophytes
a type of fungi that causes skin, hair, and nail infections
diagnosis
- determination of the nature of a disease from its symptoms and/or diagnostic tests
- federal regulations prohibit salon professionals from performing a diagnosis
diplococci
spherical bacteria that grow in pairs and cause diseases such as pneumonia
direct transmission
transmission of blood or body fluids through touching (including shaking hands), kissing, coughing, sneezing, and talking
disease
an abnormal condition of all or part of the body, or it’s systems or organs, that makes the body incapable of carrying on normal function
disinfectants
chemical products that destroy all bacterial, fungi, and viruses (but not spores) on surfaces
disinfection
- aka. disinfecting
- the process that eliminates most, but not necessarily all, microorganisms on nonporous surfaces
- this process is not effective against bacterial spores
efficacy
the ability to produce an effect
exposure incident
contact with nonintact (broken) skin, blood, body fluid, or other potentially infectious materials that is the result of the performance of an employee’s duties
flagella
- aka. cilia
- slender, hair-like extensions used by bacilli and spirilla for locomotion (moving about)
folliculitis
- aka. folliculitis barbae, sycosis barbae, or barber’s itch
- inflammation of the hair follicles caused by a bacterial infection from ingrown hairs
- the cause is typically from ingrown hairs due to shaving or other epilation methods
fungi
(singular : fungus)
- microscopic plant parasites, which include molds, mildews, and yeast
