Examples of MacConkey agar in the following topics:
-
- Sorbitol MacConkey agar is a variant of the traditional MacConkey commonly used in the detection of E. coli O157:H7 .
- Traditionally, MacConkey agar has been used to distinguish those bacteria that ferment lactose from those that do not.
- In sorbitol MacConkey agar, lactose is replaced by sorbitol.
- Sorbitol fermenting non pathogenic commensal bacteria from faeces growing on Cefixime Tellurite Sorbitol MacConkey Agar.
-
- After 24 hours, this inoculated MacConkey agar culture plate cultivated colonial growth of Gram-negative, rod-shaped, and facultatively anaerobic Proteus vulgaris bacteria.
-
- In most cases, specimens are also inoculated into differential media that define such characteristics as fermentation patters (mannitol salt and MacConkey agar) and as reactions in blood (blood agar).
-
- Mannitol salt agar (MSA) which is selective for Gram-positive bacteria and differential for mannitol.
- Xylose lysine desoxyscholate (XLD), which is selective for Gram-negative bacteria buffered charcoal yeast extract agar, which is selective for certain gram-negative bacteria, especially Legionella pneumophila.
- Blood agar (used in strep tests), which contains bovine heart blood that becomes transparent in the presence of hemolytic.
- MacConkey (MCK), which is differential for lactose fermentationmannitol salt agar (MSA), which is differential for mannitol fermentation.
-
- Typical media include Plate count agar for a general count or MacConkey agar to count gram-negative bacteria such as E. coli.
- The initial analysis is done by mixing serial dilutions of the sample in liquid nutrient agar which is then poured into bottles.
- The bottles are then sealed and laid on their sides to produce a sloping agar surface.
- In the pour plate method a diluted bacterial sample is mixed with melted agar and then that mixture is poured into a petri dish.
- Urine cultured on Oxoid Brilliance UTI Agar plate. 1uL of urine spread onto the agar surface.
