“…To our knowledge, four monoclonal antibodies (MAbs) have been demonstrated by indirect immunofluorescence assay (IFA) to be specific for the C. albicans mycelial phase (8,21,22,26,28); however, only two of these components that are recognized by Western blotting have been recovered exclusively from C. albicans hyphae (8,21). Concerning species specificity, two MAbs have been isolated; the first of these is specific to C. krusei (30) and the second of these is specific to C. albicans blastoconidia (31). In this paper we present the characteristics of a novel C. albicans germ tube-specific MAb (MAb 16B1-F10) that allows differentiation of C. albicans from the recently identified species C. dubliniensis (10,37).…”
