Virus
a parasitic submicroscopic particle that infects and resides in the cells of biological organisms. A virus is capable of replication only through taking over the host cell’s reproduction function.
Wart
is caused by highly contagious virus that has infected an area of the skin and created a generally small, rough growth that resembles a solid blister with a cauliflower-like appearance.
Hepatitis
a bloodborne virus that causes disease affecting the liver
Contamination
the presences, or the reasonably anticipated presence, or blood or other potentially infectious material on an item’s surface, or visible debris/residues, such as cust, hair and skin
Immunity
the ability of the body to destroy and resist infection. Immunity against disease can be either natural or aquired and is a sign of good health
Natural Immunity
immunity that is partly inherited and partly developed through healthy living
Acquired Immunity
immunity that the body develops after overcoming a disease through an inoculation (such as a flu vaccination) or through exposure to natural allergens, such as pollen, cat dander and regweed
Parasites
organisms that grow, feed, and shelter on or in another organisms, while contributing nothing to survival of that organism. Parasites must have a host to survive.
Scabies
a contagious skin disease that is causefd bythe itch mite, which burrows under the skin
Fungi
single-cell organisms that grow in irregular masses that include mold, mildews, and yeasts, can produce contagious diseases, such as ringworm
Mildew
a type of fungus that affects plants or grows on inanimate objects but that does not cause human infections on the salon
Bacteria
are one-celled microorganisms, organisma of microscopic or submicroscopic size, with both plant and animal characteristics
Nonpathogenic
are harmless organisms that perform useful functions and are safe to come in contact with since they do not cause harm
Pathogenic
bacteria are considered harmful because they may cause disease or infection in humans when they invade the body
Cocci
round-shaped bacteria that apper singly or in groups
Staphylococci
pus-froming bacteria that grown in clusters, like a bunch of grapes, They cause abscesses pustules and boils
Diplococci
spherical bacteria that grow in pairs and cause diseases such as pueumonia
Bacilli
short, rod-shaped bacteria
Spirilla
Spiral or corkscrew-shaped bacteria
Motility
self-movement
Flagella
slender, hairlike extensions used by bacilli and spirilla for locomotion
Binary Fission
he division of bacteria cell into new cells called daughter cells
Spores
The inactive reproductive stage of certain fungi and bacteria during which these microorganisms coat themselves with waxy outer shells so they can withstand long periods of famine, dryness, and unsuitable temperatures
Pus
a fluid created by tissue inflammation; a sign of a bacterial infection
Inflammation - a condition in which a part of the body reacts injury, irritation or infection.
