SPOROTRICHOSIS is a disease of man and animals resulting from introduction of spores of Sporotrichum schenckii from exogenous sources in nature, generally occurring through breaks in the skin and not through inhalation like other spores of coccidioidomycosis, histoplasmosis, and blastomycosis.1 Over 3,000 infections have been reported. They are generally cutaneous infections, but a form of generalized infection is also recognized.
Sporotrichum is a dimorphic organism which grows in culture in a yeastlike form at incubation temperatures and in a filamentous form at room temperature.2 Sabouraud's agar is a satisfactory cultural medium. The spores usually appear as tiny cigar shaped bodies 3μ to 5μ microns in length with 1 to 3 buds at either end. They are, however, dimorphic in character, and spheroid forms measuring up to 8μ are not uncommon. It has a worldwide distribution and is saprophytic in vegetable matter, animal excreta, and soil.
