Rhamnomannans from several isolates ofSporothrix schenckii andCeratocystis species were compared. No major differences emerged in the analysis of the carbohydrate composition of polysaccharides from either species. Methylation analysis for the identification of the glycosidic linkages present in the polysaccharides showed that they all were very similar with minor differences being observed among strains and between polysaccharides obtained at 25 and 37 C. Partially methylated derivatives were identified by gas-liquid chromatography and mass spectrometry. Their proportions suggest that polysaccharides fromS. schenckii andC. stenoceras have a general structure similar to that ofC. ulmi : a (1 → 6)-linked α-d -mannopyranosyl main chain substituted in the 3-positions by α-l -rhamnopyranosyl and in many cases by α-l -rhamnopyranosyl (1→2)-l -rhamnopyranosyl side chains. Differences among polysaccharides resided in the proportions of the dirhamnosyl side chains and of 4-O -substituted and 2, 4-di-O -substituted mannose units. Increased proportions of dirhamnosyl side chains were observed in the polysaccharides fromS. schenckii strains and from a pathogenic variant ofC. stenoceras grown at 25 C. Proton magnetic resonance spectra (H-1 region) of the rhamnomannans showed thatS. schenckii strains could be placed in two different groups similar but not identical to anyCeratocystis species. These spectra were very close to those of the polysaccharides from theC. clavata andC. ambrosia groups ofCeratocystis species.
