| Conradi-Drigalski agar | A selective, nutrient medium for isolation of Salmonella typhi and other intestinal pathogens from faecal specimens; it contains the dye crystal violet, which generally inhibits growth of Gram-positive, but not Gram-negative, bacteria. Synonym: Drigalski-Conradi agar. (05 Mar 2000) |

| cornmeal agar | A culture medium that is low in nutrients, used extensively in the study of yeastlike and filamentous fungi; it suppresses vegetative growth while stimulating sporulation of many species, and is widely used for producing the distinctive and rapidly diagnostic chlamydospores of Candida albicans. (05 Mar 2000) |
| potato dextrose agar | A culture medium used extensively for the cultivation of fungi; especially good for development of conidia and other sporulating forms by which an organism is identified microscopically. (05 Mar 2000) |
| Sabouraud's agar | A culture medium for fungi containing neopeptone or polypeptone agar and glucose, with final pH 5.6; it is the standard, most universally used medium in mycology and is the international reference. Modified Sabouraud's agar (Emmons modification) with less glucose is better for pigment development in the colonies. Synonym: French proof agar. (05 Mar 2000) |
| Sabouraud's dextrose agar | A dextrose peptone media that supports the growth of most pathogenic fungi. (05 Mar 2000) |
| Czapek's solution agar | A culture medium used for the cultivation of fungus species and for identification of Aspergillus and Penicillium species. Synonym: Czapek-Dox medium. (05 Mar 2000) |
| serum agar | An enriched medium for cultivation of fastidious organisms; prepared by adding sterile serum to melted agar. (05 Mar 2000) |
| soft agar | <cell culture> Semi solid agar used to gelate medium for culture of animal cells. Placed in such a medium, over a denser agar layer, the cells are denied access to a solid substratum on which to spread, so that only anchorage independent (usually transformed) cells are able to grow. (18 Nov 1997) |
| Novy and MacNeal's blood agar | A nutrient agar containing two volumes of defibrinated rabbit's blood; suitable for the cultivation of a number of trypanosomes. (05 Mar 2000) |
| nutrient agar | A simple solid medium containing beef extract, peptone, agar, and water; used for growing many common heterotrophic bacteria. (05 Mar 2000) |
| Drigalski-Conradi agar | A selective, nutrient medium for isolation of Salmonella typhi and other intestinal pathogens from faecal specimens; it contains the dye crystal violet, which generally inhibits growth of Gram-positive, but not Gram-negative, bacteria. Synonym: Drigalski-Conradi agar. (05 Mar 2000) |
| oatmeal-tomato paste agar | A special culture medium for the production of ascospore formation in the dermatophytes. (05 Mar 2000) |
| Thayer-Martin agar | A Mueller-Hinton agar with 5% chocolate sheep blood and antibiotics, used for transport and primary isolation of Neisseria gonorrhoeae and Neisseria meningitides. Synonym: Thayer-Martin medium. (05 Mar 2000) |
| electrophoresis, agar gel | Electrophoresis in which agar or agarose gel is used as the diffusion medium. (12 Dec 1998) |
| EMB agar | Agar composed of peptone, lactose, and sucrose and containing eosin and methylene blue, used to distinguish between lactose-fermenting and non-lactose-fermenting Gram-negative bacteria. Synonym: EMB agar. (05 Mar 2000) |
