·
Sheep blood agar
supports the growth of most bacteria, both gram-positive and gram-negative.
·
Chocolate agar
provides the growth requirements for fastidious organisms such as H. influenzae or N. gonorrhoeae, as
well as for most other less-fastidious bacteria.
·
MacConkey agar supports most gram-negative rods,
especially the Enterobacteriaeceae, but inhibits
growth of gram-positive organisms and some fastidious gram-negative bacteria,
such as haemophilus and neisseria
species.
·
Thayer-Martin
medium, which is composed of chocolate agar supplemented with
several antibiotics, suppresses the growth of nonpathogenic Neisseria
and other normal and abnormal flora, but permits the growth of gonococcus.
·
Hektoen enteric agar, Xylose Lysine
DCA Agar are also a selective
medium often used to culture Salmonella and Shigella
species.
·
C. diphtheriae can be
isolated most easily from a selective medium, such as Tinsdale's
agar, which contains potassium tellurite.
·
Loeffler's coagulated serum medium. On this medium, C diphtheriae produces polyphosphate storage granules (called
volutin granules) that stain variegated blue/red (metachromatic).
·
Tellurite-containing differential medium. C diphtheriae imports and reduces tellurite,
turning the colonies gray to black.
·
Mycoplasma or PPLO culture medium: mycoplasma
·
Regan-Lowe or
Bordet-Gengou medium: Bordetella
pertussis
·
S.aureus is the only
Staphylococcus to grow on mannitol salt agar with fermentation of the mannitol and production of acid. (This is a surveillance medium.)
·
charcoal yeast
extract medium: LEGIONELLA PNEUMOPHILA
·
potassium cyanide
medium: MORGANELLA MORGANII
·
C. albicans is
identified by the ability to produce germ tubes and/or chlamydospores
in cornmeal agar
·
Thiosulfate citrate bile salts sucrose (TCBS) medium: V.cholerae
·
Mueller Hinton
Agar: Meningococci
·
BCYE = Buffered
Charcoal Yeast Agar: Legionells
·
Wagatsuma Agar: V.parahaemolyticus (Kanagava
Phenomenon)
·
Cysteine Glucose Blood Agar: F.tularensis
·
Nonnutrient agar overlaid with E.coli:
N.fowleri / Acanthameba
·
cefsulodin-irgasan-novobiocin (CIN) - a medium selective for Yersinia
·
Sabouraud dextrose agar, which, because of its low pH
(5.0), inhibits bacterial growth while allowing fungal colonies to form: Most
fungi
·
Lowenstein-Jensen
medium: an egg-based solid medium that supports the growth of
Mycobacterium species, including M. tuberculosis.
·
Eosin methylene blue: differentiates E coli as
metallic green colonies, whereas pathogenic, nonlactose-fermenting
Salmonella and Shigella organisms are translucent.
Inhibits gram-positive organisms via aniline dyes.
·
Salmonella-Shigella (bile salt and sodium citrate)
·
Campy agar:
campylobacter jejuni
·
Skirrow agar: campylobacter jejuni
