Comparison of immunodiffusion and crossed-immunoelectrophoresis in the diagnosis of invasive candidiasis. 1983

A N Vanmali, and A L Lentnek, and J Franco, and B Z Ngwenya

A retrospective single blind study was conducted to compare the efficacy of crossed-immunoelectrophoresis using concanavalin A intermediate gel with double immunodiffusion tests in the diagnosis of invasive candidiasis. On the basis of cytoplasmic antibody detection, crossed-immunoelectrophoresis with concanavalin A differentiated reliably between Candida albicans fungemia and invasive candida infection, whereas double immunodiffusion did not. With regard to sensitivity, specificity, and predictive value crossed-immunoelectrophoresis with concanavalin A was superior to double immunodiffusion. Analysis of double immunodiffusion precipitin bands revealed fuzzy and sharp precipitin bands which corresponded to mannan (fuzzy) and cytoplasmic (sharp) antibodies in the crossed-immunoelectrophoresis with concanavalin A assay. Therefore, the finding of sharp bands in the double immunodiffusion procedure supports the diagnosis of invasive candidiasis.

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).
