Abstract

Ethanol-precipitable culture filtrate antigens of 100 strains of 75 species of the Sporothrix-Ceratocystis-Europhium-Graphium complex and 1 species of Botrytis were examined for neutral sugar components and for serological cross-reactivity with S. schenckii rabbit antiserum and human sporotrichosis sera by capillary precipitin and double immunodiffusion assay. Results revealed that cross-reactive species (60 of 77, ca. 80%) produced exoconidial forms and rhamnose- and mannose-containing polysaccharides and included Ceratocystis, the three known Europhium, and several Graphium-form species. Endoconidial-form Ceratocystis species did not cross-react.
