A | B |
Aerobes (aerobic) | Microorganisms that require oxygen to live and grow |
Anaerobes (anaerobic) | Microorganims that do not require the presence of oxygen to live and reproduce |
Autotrophic | Self-nourishing. Pertains to green plants and bacteria which form protein/carbohydrates from inorganic salts/ carbon dioxide |
Bacteria | Most common group of microbes. Essential to life; many reside naturally in the body. Cause disease when a person is compromised |
Binary fission | The process by which bacteria reproduce |
Endotoxin | Bacterial toxin confined within the body of a bacterium, freed only when the bacteria is broken down |
Exotoxin | A toxin produced by a microorganism and excreted into its surrounding medium. Most potent toxins known |
Fomite | Inanimate object which act as reservoirs for infection.(Clothes/utensils/contaminated equipment/surgical instruments |
Fungi | Eucaryotic organisms including mushrooms, molds and yeasts |
Gram negative bacteria | Bacteria which appear red/pink following a staining process |
Gram positive bacteria | Bacteria which retain a purple color when subjected to a staining process |
Heterotrophic | Organisms which require complex organic food to grow and develop |
Host | The organism from which a parasite gets its nourishment |
Infection | Term used when nonresident flora invade a susceptible area/host |
Inflammation | The body's response to infection. Signs/symtoms: redness, heat, swelling (edema), pain, pus |
Microorganisms | Living organisms to small to be seen with the naked eye |
Nosocomial infection | Infection that develops while a patient is in the hospital or is produced by microbes during hospitalization |
Opportunist | A microbe with potential to cause disease given the opportune time or place |
Pathogenic microorganism | A disease causing/producing microorganism |
Prinary invader | First, initial microorganism causing infection |
Protozoa | Eucaryotic, usually single-celled, animal like microorganism |
Pyogenic organism | Pus producing microorganism |
Septicemia | "Blood poisoning". Systemic disease associated with pathogenic microbes/toxins in blood |
Spores | Formed by some bacteria as a means of survial |
Vector | Animate carrier of microorganisms, many times an arthropod |
Virulence | The degree of pathogenicity os a microorganism |
Virus | Small, simple structured "particle" reliant of its host for survival. Causes hepatitis and HIV |
Bacteremia | The presence of bacteria in blood |
Acute infection | An infection of sudden onset and short duration |
Algae | Group of microbes abundantly found, many beneficial. Example: seaweed |
Carrier | Person who harbors a microorganism but is asymptomatic, may spread the disease |
Chronic infection | Infection of slow progression, long duration |
Infectious agent | Microorganism which produces a specific disease |
Latent infection | Disease which reaches a stage where the patient is not symptomatic but still harbors the microorganism |
Local infection | An infection confined within an area |
Parasite | Organism that lives within, upon ar at the expense of a host |
Primary disease | First disease or infection |
Prion | An infectious protein affecting the central nervous system. Ex: mad cow disease Cruetsfeld-Jakob disease) |
Pus | The liquid producto of inflammation, usually yellow in color |
Resident microorganism | "Normal flora" Microorganism which are normally found in an area |
Rickettsiae | Group of microorganisms transmitted by vectors. (Example: Rocky Mountain Spotted Fever) |
Saprophyte | Microorganism whose main source of foof is dead and decaying organic matter |
Secondary disase | A second illness encoutered due to a weakened resistance from an original disease |
Shedder | Individuals who carry and shed staphylococcus at a higher volume/rate |
Superinfection | Second infection due to the use of antibiotics or disruption of the normal flora |
Suppuration | the process of pus formation |
Systemic infection | An infection which occurs throughout the body |
Toxin | Poisons released by microorganisms |
Transient microorganism | Temporary flora, not part of the normal flora |
