¹³C-NMR of the rhamnomannan fraction isolated from the strains presenting less virulence in yeast phase. Sporothrix schenckii 4822 (A) and S. brasiliensis 4824 (B) show the signals associated to type I rhamnomannan (red and black arrows), but also a signal corresponding to C-1 of α-L-Rhap nonreducing end unit of α-L-Rhap-(l, 2)-α—Rhap and 2,4-di-0-substituted α-D-mannopyranose units (Cian arrows; Travassos, 1985), which suggest longer side chains in the cell wall for these two strains.
