Sabourauddextrose

Sabourauddextrose is not a standard term in microbiology and does not denote a distinct, regulated compound in major reference sources. It is likely a nonstandard or misspelled variant of Sabouraud dextrose medium, a widely used culture medium for fungi.

Sabouraud dextrose medium, named after French dermatologist Raymond Sabouraud, is formulated to promote fungal growth while inhibiting many bacteria. The solid agar version typically contains a high concentration of dextrose (glucose) and peptone, with an acidic pH around 5.6, and agar to provide a solid surface. The common formulation is roughly 4% dextrose, 1% peptone, and 2% agar, prepared in distilled water and sterilized by autoclaving. Variations exist among manufacturers, and some formulations include antibiotics such as chloramphenicol to suppress bacterial contamination or cycloheximide to inhibit rapidly growing saprophytic fungi.

Uses and applications of Sabouraud dextrose medium include clinical mycology and basic fungal research. It supports the growth of yeasts and molds, allowing for colony formation, morphological observation, and preliminary identification. For clinical specimens, media may be supplemented with antibiotics to improve isolation from mixed flora. In research settings, SDA can be used to culture a broad range of fungi, assess growth characteristics, and screen antifungal agents.

History and naming: Sabouraud dextrose medium credits its origin to Sabouraud’s early work on fungal culture techniques in the late 19th and early 20th centuries. While often referred to in shorthand as Sabouraud dextrose, the exact spelling “Sabourauddextrose” is not established in standard reference works and should be interpreted as a likely variant spelling of the familiar medium rather than a separate substance.
