Microbiology and Infection Prevention
| Question | Answer |
|---|---|
| microbiology | the study of micro organisms |
| contamination | the state of being soiled or infected by contact with infectious organisms |
| micron | a unit of measure equal to 1/1000 of a millimeter |
| protoplasm | a thick mucous like substance that is colorless and translucent that forms the biochemical basis of life found within the cell nucleus |
| nucleus | the functional center of a cell that governs activity and heredity |
| phagocytosis | the process by which some cells can ingest bacteria or foreign objects |
| DNA | deoxyribonucleic acid. the protein found in the chromosomes of a cell nucleus which is the basis of heredity |
| spore | micro organism capable of forming a thick wall around itself to survive adverse conditions |
| chlorophyll | a molecule in plants that absorbs sunlight and converts it to energy |
| aerobic | capable of growing in the presence of oxygen, requiring oxygen |
| anaerobic | capable of growing in the absence of oxygen, not requiring oxygen |
| psychrophiles | cold loving bacteria which thrive at temps of 59°–68° f |
| mesophiles | bacteria that grow best at moderate temperatures 68°–113° f,are often pathogenic to humans because they grow best at body temperature |
| thermophiles | bacteria which grow best at 122°–158° f |
| vegetative | vegetative stage state of active growth of micro organisms |
| angstrom | a unit of measure of light |
| binary fission | The typical method of bacterial reproduction in which one cell divides into two |
| MRSA | methicillin resistant staphylococcus aureus |
| VRE | vancomycin resistant enterococcus |
| viruses | minute infectious agent that only grows in living tissues or cells |
| host | an animal plant or human that supports the growth of micro organisms |
| protozoan | a one celled animal like micro organism of the sub–kingdom protazoa |
| amoeboid movement | the crawling movement of cells |
| causative agent | the micro organism that causes an infectious disease |
| reservoir of agent | the place where an infectious agent can survive |
| carriers | an individual who harbors and disseminates pathogens without having symptoms |
| portal of exit | the path by which an infectious agent leaves the reservoir |
| mode of transmission | the method of transfer of an infectious agent from reservoir to a susceptible host |
| portal of entry | the path used by an infectious agent to enter susceptible host |
| susceptible host | a person or animal that lacks the ability to resist infection |
| infection | invasion of human body tissue by micro organisms |
| hand hygiene | the act of washing ones hands with soap and water or an alcohol scrub |
| PPE | personal protective equipment |
| standard precautions | using appropriate barriers to prevent transmission of infectious organisms. assumes every patient blood and body fluids is infectious |
| fomite | an inanimate object that can transmit micro organisms |
| asepsis | the absence of micro organisms that cause disease |
| aseptic technique | activity or procedure that prevents infection or breaks the chain of infection |
| medical asepsis | procedures performed to reduce the number of micro organisms to minimize their spread |
| surgical asepsis | procedures performed to reduce the number of all micro organisms and / or to prevent the introduction of micro organism into an area |
| Gram–stain and Ziehl–Neilson stain | The two most common processes designed to classify bacteria by color changes. |
