|---|---|
| Asepsis | freedom from infection |
| Bacteria | Prokaryotic, ubiquitous single-celled organisms |
| Bloodborne Pathogens | Disease-causing microorganisms that may be preset in human blood |
| Chemotherapy | Treatment of disease by chemical agents |
| Cyst | Stage in the life cycle of certain parasites during which they are enclosed in a protective wall |
| Dimorphic | occurring in two distinct forms |
| Diseases | Deviations from or interruptions of the normal structure or function of any part, organ, or system of the body that are exhibited by a characteristic set of symptoms & signs & whose cause, pathologic mechanism, & prognosis may be known or unknown |
| Disinfectants | Chemicals used to free an environment from pathogenic organisms or to render such organisms inert, especially as applied to the treatment of inanimate materials to reduce or eliminate infectious organisms |
| Eukaryotes | Organism whose cells have a true nucleus |
| Flora | Microbial community found in or on a healthy person |
| Fomite | An object such as a book, wooden object, or ab article of clothing that is not in itself harmful but is able to harbor pathogenic microorganisms & thus may serve as an agent of transmission of an infection |
| Fungi | General term used to denote a group of eukaryotic protists |
| Health-Care Associated Infection (HAI) | Infection that patients acquire while they are receiving treatment for another health care issue |
| Host | An animal or plant that harbors or nourishes another organism |
| Iatrogenic | resulting from activities of physicians |
| Immunity | Security against a particular disease |
| Infection | Invasion & multiplication of microorganisms in body tissues that may be clinically inapparent or that may result in local cellular injury |
| Medical Asepsis | Reduction in numbers of infectious agents, which, in turn, decreases the probability of infection but does not necessarily reduce it to zero |
| Microorganisms | Microscopic organisms |
| Nosocomial | Pertaining to or originating in the hospital- said of an infection not present or incubating before admittance to the hospital but generally developing after 72 hours after admittance |
| Pathogens | Disease-producing microorganisms |
| Prokaryotes | Cellular organisms that lack a true nucleus |
| Protoza | A subkingdom comprising the simplest organisms of the animal kingdom |
| Reservoir | Alternative or passive host or carrier that harbors pathogenic organisms, without injury to itself, and serves as a source from which other individuals can be infected |
| Standard Precautions | Precautions to prevent the transmission of disease of body fluids and substances |
| Sterilization | Complete destruction or elimination of all living microorganisms |
| Surgical Asepsis | Procedure used to prevent contamination by microbes, and endospores before, during, or after surgery using sterile technique |
| Vaccine | Suspension of attenuated or killed microorganisms administered for the prevention, improvement, or treatment of infectious disease |
| Vector | A carrier, especially an animal, that transfers an infective agent from one host to another |
| Virion | Complete viral particle found extracellularly and capable of surviving in crystalline form and infecting a living cell; comprises the nucleoid (genetic material) and the capsid; also called a viral particle |
| Viruses | any group of minute infectious agents not resolved in the light microscope, with certain exceptions and characterized by a lack of independent metabolism as well as the ability to replicate only within living host cells |
