Sources of Sporotrichosis
The fungus lives in sphagnum moss, hay, other plant materials, and soil. The fungus can enter the skin through small cuts or punctures from thorns, barbs, pine needles, or wires. In rare cases, inhalation of the fungus can cause pulmonary infection. Sporotrichosis is not spread from person to person; however, a small number of human cases have been caused by scratches or bites from infected animals such as cats.
