BIGGY Agar is used for the isolation and differentiation of Candida spp. in a laboratory setting. BIGGY Agar is not intended for use in the diagnosis of disease or other conditions in humans.

BIGGY Agar is a modification of the formula described by Nickerson. BIGGY Agar, an abbreviation for Bismuth Glucose Glycine Yeast Agar, is also referred to as Nickerson Agar and Nickerson Candida Selective Agar. BIGGY Agar was developed while studying sulfite reduction by Candida spp. Nickerson found that Candida albicans can be differentiated from other Candida spp. on this medium based on colony morphology.

Candidiasis, the most frequently encountered opportunistic fungal infection is usually caused by Candida albicans. Candida tropicalis and Candida (Torulopsis) glabrata infections occur less frequently. Candida spp. are present in samples as a result of environmental contamination, colonization, or an actual disease process.
