Chemotherapy

Back 4

treatment of disease by chemical agents

Front 5

Cyst

Back 5

stage in the life cycle of certain parasites during which thay are enclosed in a protective wall

Front 6

Dimorphic

Back 6

occurring in two distinct forms

Front 7

Disease

Back 7

any deviation from or interruption of the normal structure or function of any part, organ, or system (or combination thereof) of the body that is exhibited by a characteristic set of symptoms and signs and whose cause, pathologic mechanism, and prognosis may be known or unknown

Front 8

Disinfectant

Back 8

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 infections organisms

Front 9

Eucaryotes

Back 9

organisms whose cells have a true nucleus

Front 10

Flora

Back 10

microbial community found on or in a healthy person

Front 11

Fomite

Back 11

object, such as a book, wooden object, or article of clothing, that is not in itself harmful but is able to harbor pathogenic microorganisms and thus may serve as an agent of transmission of an infection

Front 12

Fungi

Back 12

general term used to denote a group of eucaryotic protists- including mushrooms, yeasts, rusts, molds, and smuts- that are characterized by the absence of chlorophyll and by the presence of a rigid cell wall

Front 13

Host

Back 13

animal or plant that harbors or nourishes another organism

Front 14

Iatrogenic

Back 14

resulting from the activities of physicians

Front 15

Immunity

Back 15

security against a particular disease

Front 16

Infection

Back 16

invasion and multiplication of microorganisms in body tissues that may be clinically inapparent or result in local cellular injury as a result of competitive metabolism, toxins, intracellular replication, or antigen-antibody response

Front 17

Medical Asepsis

Back 17

reduction in numbers of infectious agents, which, in turn, decreases the probability of infection but does not necessarily reduce it to zero

Front 18

Microorganism

Back 18

microscopic organism; those of medical interest include bacteria, viruses, fungi, and protozoa

Front 19

Nosocomial

Back 19

pertaining to or originating in the hospital; said of an infection not present or incubating before admittance to the hospital but generally occurring 72 hours after admittance

Front 20

Pathogen

Back 20

any disease-producing microorganism

Front 21

Procaryotes

Back 21

cellular organisms that lack a true nucleus

Front 22

Protozoa

Back 22

a subkingdom comprising the simplest organisms of the animal kingdom, consisting of unicellular organisms that range in size from submicroscopic to macroscopic; most are free living, but some lead commensalistic, mutualistic, or parasitic existences

Front 23

Reservoir

Back 23

alternate 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

Front 24

Standard Precautions

Back 24

precautions to prevent the transmission of disease by body fluids and substances

Front 25

Sterilization

Back 25

complete destruction or elimination of all living microorganisms, accomplished by physical methods (dry or moist heat), chemical agents (ethylene oxide, formaldehyde, alcohol), radiation (ultraviolet, cathode), or mechanical methods (filtration)

Front 26

Surgical Asepsis

Back 26

procedure used to prevent contamination by microbes and endospores before, during, or after surgery using sterile technique

Front 27

Vaccine

Back 27

suspension of attenuated or killed microorganisms (bacteria, viruses, or rickettsiae) administered for the prevention, improvement, or treatment of infectious disease

Front 28

Vector

Back 28

carrier, especially an animal (usually an arthropod), that transfers an infective agent from one host to another

Front 29

Virion

Back 29

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 viral particle

Front 30

Virus

Back 30

any group of minute infectious agents not resolved in the light microscope, with certain exceptions (e.g., poxvirus), and characterized by a lack of independent metabolism and by the ability to replicate only within living host cells
