| blood agar | <cell culture> An agar-based medium which hasbeen enriched with sterilised, defibinated blood (sheep, rabbit or horse). It is used for primary plating andsubculturing, especially to determine bacterial haemolysis. (09 Oct 1997) |
| Bordet-Gengou potato blood agar | Glycerine-potato agar with 25% of blood, used for the isolation of Bordetella pertussis. (05 Mar 2000) |
| brain-heart infusion agar | A medium used for the isolation of fastidious microorganisms, especially fungi. (05 Mar 2000) |
| brilliant green salt agar | A highly selective culture medium consisting of agar with peptone, lactose, sodium taurocholate, brilliant green, and picric acid solution used in the primary isolation of enteric pathogens such as Salmonella species. (05 Mar 2000) |
| MacConkey agar | Medium containing peptone, lactose, bile salts, neutral red, and crystal violet used to identify Gram-negative bacilli and characterise them according to their status as lactose fermenters. Fermenters appear as red colonies while nonfermenters are colourless. (05 Mar 2000) |
| rice-Tween agar | A useful medium for the development of the differential chlamydospores in Candida albicans and for preparation of slide cultures for other forms of sporulation in other fungal species. (05 Mar 2000) |
| chocolate agar | Blood agar heated until the blood becomes brown or chocolate in colour, used especially to isolate Haemophilus influenza or Neisseria species. (05 Mar 2000) |
| cholera agar | An alkaline agar medium for cultivating Vibrio cholerae. (05 Mar 2000) |
| Guarnieri's gelatin agar | A type of agar, similar to Stoddart's gelatin agar, used for the cultivation of Streptococcus pneumoniae. (05 Mar 2000) |
| Pfeiffer's blood agar | Solid agar with a few drops of human blood smeared on the surface. (05 Mar 2000) |
| Mueller-Hinton agar | Medium containing beef infusion, peptone, and starch used primarily for the disk-agar diffusion method for antimicrobial susceptibility testing. (05 Mar 2000) |
| 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) |
