Identification of species of Candida, Cryptococcus, and Torulopsis by gas-liquid chromatography. 1979

P K Gangopadhyay, and H Thadepalli, and I Roy, and A Ansari

Gas-liquid chromatography was used to identify species of Candida, Cryptococcus, and Torulopsis by fatty-acid analysis of the whole-cell hydrolysate. Candida albicans characteristically revealed 2-OH C14:0 and C19:0 (chain length:number of double bonds); these were absent in other organisms. Candida curvata was characterized by a ratio of C16:1 to C16:0 of greater than 1.0. Candida guilliermondii contained C10:0, and Candida tropicalis had no C12:0, these features were used for their identification. Cryptococcus was characterized by the absence of C16:1. Torulopsis was characterized by a C16:1 to C16:0 ratio of greater than 10 accompanied by the presence of one unidentified fatty acid. These data suggested that certain Candida, Cryptococcus, and Torulopsis (the clinically important yeast-like organisms) may be identified by gas-liquid chromatography.

D002175	Candida	A genus of yeast-like mitosporic Saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. It is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including CANDIDIASIS; ONYCHOMYCOSIS; VULVOVAGINAL CANDIDIASIS; and CANDIDIASIS, ORAL (THRUSH).

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
