Sporothrix schenckii is a
fungus that can be found world-wide in the environment. The
species is present in soil as well as in and on living and decomposing plant material such as
peat moss. It can infect humans as well as animals and is the causative agent of
sporotrichosis, commonly known as "rose handler's disease". The most common route of infection is the introduction of
spores to the body through a cut or puncture wound in the skin. Infection commonly occurs in otherwise
healthy individuals but is rarely life-threatening and can be treated with antifungals. In the environment it is found growing as filamentous
hyphae. In host tissue it is found as a
yeast. The transition between the hyphal and yeast forms is temperature dependent making
S. schenckii a
thermally dimorphic fungus.
