| 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) |
| Endo agar | A medium containing peptone, lactose, dipotassium phosphate, agar, sodium sulfite, basic fuchsin, and distilled water; originally developed for the isolation of Salmonella typhi, this medium is now most useful in the bacteriological examination of water; coliform organisms ferment the lactose, and their colonies become red and colour the surrounding medium; non-lactose-fermenting organisms produce clear, colourless colonies against the faint pink background of the medium. Synonym: Endo's medium. (05 Mar 2000) |
| Endo's fuchsin agar | Nutrient agar containing lactose, alcoholic solution of fuchsin, sodium sulfite, and soda solution, used as a culture medium to differentiate Salmonella typhi from coliform bacteria. Synonym: fuchsin agar. (05 Mar 2000) |
| eosin-methylene blue 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) |
| yeast extract agar | A medium used to induce sporulation and reduce vegetative growth in the cultivation of fungi. (05 Mar 2000) |
| lactose-litmus agar | Agar made by adding 2% lactose and litmus to acid-free nutrient agar; formerly used in the identification of Salmonella typhi. (05 Mar 2000) |
| French proof 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) |
| fuchsin agar | Nutrient agar containing lactose, alcoholic solution of fuchsin, sodium sulfite, and soda solution, used as a culture medium to differentiate Salmonella typhi from coliform bacteria. Synonym: fuchsin agar. (05 Mar 2000) |
| acid salt | A salt in which not all of the ionizable hydrogen of the acid is replaced by the electropositive element; e.g., NaHSO4, KH2PO4. Synonym: bisalt, protosalt. (05 Mar 2000) |
