Brain-heart infusion agar with antibiotics


Inhibitory mold agar


Dermatophyte test medium


For identification
Potato dextrose agar


Cornmeal agar with Tween 80

General medium. pH 5.6 inhibits bacteria. Grows most molds & yeast.

Antibiotics inhibit fungal contaminants & bacteria. Dermatophytes & most fungal
pathogens grow.

For isolation & conversion of dimorphic fungi from mold to yeast phase. Used for normally
sterile specimens.

Selective medium used for isolation of pathogenic fungi from specimens contaminated
with bacteria.

For recovery of fungi from specimens contaminated with bacteria. Contains chloram-
phenicol & gentamicin to inhibit bacteria.

For recovery of dermatophytes from skin, hair, nails. Turn agar from yellow to red.
Antibiotics inhibit bacteria.

Stimulates sporulation of molds. Good for slide cultures.

To differentiate Candidaspecies. C. albicansproduces chlamydospores.

Detection of urease production by C. neoformans.

Isolation of C. neoformans. Black-brown colonies in 4–7 days.
