2. to induce such propagation.

3. the product of such propagation.cul´tural

cell culture  a growth of cells in vitro; although the cells proliferate they do not organize into tissue.

continuous flow culture  the cultivation of bacteria in a continuous flow of fresh medium to maintain bacterial growth in logarithmic phase.

hanging-drop culture  a culture in which the material to be cultivated is inoculated into a drop of fluid attached to a coverglass inverted over a hollow slide.

plate culture  one grown on a medium, usually agar or gelatin, on a Petri dish.

primary culture  a cell or tissue culture started from material taken directly from an organism, as opposed to that from an explant from an organism.

pure culture  a culture of a single cell species, without presence of any contaminants.

slant culture  one made on the surface of solidified medium in a tube which has been tilted to provide a greater surface area for growth.

stab culture  one in which the medium is inoculated by thrusting a needle deep into its substance.

streak culture  one in which the medium is inoculated by drawing an infected wire across it.

suspension culture  a culture in which cells multiply while suspended in a suitable medium.

tissue culture  maintenance or growth of tissue, organ primordia, or the whole or part of an organ in vitro so as to preserve its architecture and function.

type culture  a culture of a species of microorganism usually maintained in a central collection of type or standard cultures.

Culture

A laboratory procedure in which a sample from a wound, the blood or other body fluid is taken from an infected person. The sample is placed in conditions under which bacteria can grow. If bacteria grow, identification tests are done to determine the bacteria species causing the infection.

culture,

n 1. language, values, customs, and aesthetics of an individual or a group of people; culture influences attitudes about health and health care.
2. growth of bacteria, fungi, or viruses on or in nutritive media in the laboratory.

culture,

n 1. the growth of microorganisms or other living cells on artificial media.
2. a set of learned values, beliefs, customs, and behavior that is shared by a group of interacting individuals.

culture, bacterial,

n the bacterial growth on or in an artificial medium. The medium used may be selective for a given type or genus of organism (e.g., tomato juice agar for lactobacilli).

culture, endodontic,

n the growth of microorganisms obtained from root canals or periapical tissues.

culture, endodontic medium,

n a type used for endodontic cultures.

culture medium,

n a type used for cultivating bacteria.

culture

1. the propagation of microorganisms or of living tissue cells in special media conducive to their growth.

2. to induce such propagation.

3. the product of such propagation.

anaerobic culture

one carried out in the absence of air.

continuous flow culture

the cultivation of bacteria in a continuous flow of fresh medium to maintain bacterial growth in logarithmic phase.

explant culture

a small piece of tissue such as trachea or gut maintained in culture.

hanging-drop culture

a culture in which the material to be cultivated is inoculated into a drop of fluid attached to a coverglass inverted over a hollow slide.

primary culture

a cell or tissue culture started from material taken directly from an organism. Subsequent passages of cells are referred to as secondary cultures.

secondary culture

a subculture derived from a primary culture.

slant culture

one made on the surface of solidified medium in a tube which has been tilted when the agar was solidifying to provide a greater surface area for growth.

stab culture

a culture into which the organisms are introduced by thrusting a needle deep into the medium.

streak culture

one in which the medium is inoculated by drawing an infected wire loop across it.

suspension culture

a culture in which cells multiply while suspended in a suitable liquid medium.

tissue culture

the maintaining or growing of tissue, organ primordia, or the whole or part of an organ in vitro so as to preserve its architecture and function. Used loosely to refer to monolayer cell cultures. See explant culture (above).

type culture

a culture of a species of microorganism usually maintained in a central reference collection of type or standard organisms.
