Abstract

Antisera against native yeast of 6 species, Candida intermedia, C. parapsilosis, C. guilliermondii, C. lambica, Crytococcus laurentii, and Rhodotorula rubra, were prepared for use as probes in an enzyme-linked immunosorbent assay (ELISA).These antisera reacted with yeast cell surface antigens that are thought to consist of protein moieties.The cross-reactivities between the antisera and yeast of ll species were investigated by immunofluorescent and immunoblotting methods.It was shown that ELISAusing the antiserum against C. intermedia or C. parapsilosis, is a valuable meansof detecting yeast in orange juice.Yeast of more than 103 were capable of being detected by ELISA.
