Mapping of beta-1,2-linked oligomannosidic epitopes among glycoconjugates of Candida species

Microbiology (Reading). 1995 Oct:141 ( Pt 10):2693-7. doi: 10.1099/13500872-141-10-2693.

Abstract

The distribution of beta-1,2-linked oligomannosides among glycoconjugates of various Candida species was investigated by Western blotting, using monoclonal and polyclonal antibodies which react with these epitopes. Expression of beta-1,2-linked oligomannosidic epitopes on a 14-18 kDa polydisperse antigen nonreactive with concanavalin A (ConA), previously identified as a C. albicans serotype A phospholipomannan (PLM), appeared to be restricted to C. albicans serotypes A and B (including var. C. stellatoidea types I and II) and C. tropicalis. In C. albicans, beta-1,2-linked oligomannosidic epitopes also appeared to be slightly associated with high molecular mass (> 100 kDa) polydisperse ConA-reactive mannoproteins. For all the other Candida strains investigated, belonging to the species C. parapsilosis, C. krusei, C. glabrata and C. robusta (S. cerevisiae), beta-1,2-linked oligomannosidic epitopes were found to be present in association with medium molecular mass (18-100 kDa) and high molecular mass ConA-reactive mannoproteins, giving reproducible labelling profiles that varied between species.
