Sporothrix schenckii

Sporothrix schenckii is a fungus that is the causative agent of Sporotrichosis, a disease primarily affecting the skin, bones, and sometimes the lungs. This fungus is found worldwide, particularly in soil, hay, sphagnum moss, and plants.

Taxonomy[edit | edit source]

Sporothrix schenckii belongs to the Ascomycota division of fungi, specifically within the Ophiostomatales order. It is the type species of the Sporothrix genus.

Morphology[edit | edit source]

Sporothrix schenckii is a dimorphic fungus, meaning it can exist in two different forms. At room temperature, it grows as a filamentous fungus, while at body temperature, it transforms into a yeast form.

Pathogenesis[edit | edit source]

The fungus enters the body through small cuts or punctures in the skin, often as a result of handling contaminated material. Once inside, it can cause a localized infection or spread to other parts of the body. The most common form of infection is cutaneous sporotrichosis, which presents as a chain of skin nodules or ulcers along the lymphatic vessels.

Diagnosis and Treatment[edit | edit source]

Diagnosis of Sporothrix schenckii infection is typically confirmed through culture of the fungus from a skin lesion. Treatment usually involves oral antifungal medication, such as itraconazole.

Epidemiology[edit | edit source]

Sporothrix schenckii is found worldwide, but is most common in tropical and subtropical regions. It is often associated with gardening, farming, and other activities that involve contact with soil and vegetation.
