aerobic bacteria bacteria that requires oxygen to grow
anaerobic bacteria bacteria that does not require oxygen to grow
antibody a protein specific to a certain antigen that weakens or destroys pathogens
antigen a pathogen or any other substance that induces an antibody response
antiseptic a cleansing agent that can be applied to living tissue to destroy pathogens
asepsis a state in which pathogens are absent or reduced. There are 2 principal types of asepsis; medical and surgical
asymptomatic without clinical signs or symptoms
autoclave a device using steam for sterilzation
bactericidal killing microorganisms
bacteriostatic reducing or inhibiting the number of microorganisms
chronic infection one that is persistent over a long period, perhaps for life
contagious disease a disease that is spread from person to person
contamination the presence of pathogens on an object
disinfectant a chemical substance that destroys or eliminates specific species of infectious microorganisms. It is not usually effective against bacterial spores.
disnfection a more thorough removal of contaminants than sterilization
immunity an individual's ability to fight off disease
immunoglobulin a serum that contains antibodies that can help protect an exposed person from contracting the disease
exacerbation a period in which a chronic infection shows symptoms
infection a disease process that results from the entry and spread of a microorganism
latent infection one in which the symptoms disappear and recur, while the disease-causing agent remains in the body
local infection an infection that is confined to a specific region of the body, ex. your finger

sterilant a substance that destroys or eliminates all forms of microbial life in an inanimate environment
sterile techniques methods to avoid contamination of sterile materials
sterile completely free of pathogens
sterilization the process of destroying all microorganisms including bacterial endospores and viruses. This is the highest level of cleanliness
systemic infection an infection that has spread to more than one region of the body
teratogenic causing abnormalities in the fetus
topical applied to the skin or affected area
virulence the power of a microbe to produce disease in a particular host
opportunistic infection an infection that does not ordinarily cause disease but does so under certain circumstances, for example, in compromised immune systems; so called because it takes advantage of an "opportunity"
