Not true regarding sporotrichosis is
**Core Concept**
Sporotrichosis is a fungal infection caused by Sporothrix schenckii, which primarily affects the skin and subcutaneous tissue. It is typically acquired through traumatic inoculation of the fungus into the skin, often from thorns, rose thorns, or other plant material.
**Why the Correct Answer is Right**
The correct answer will be related to the characteristics, transmission, or clinical features of sporotrichosis. Sporotrichosis is known for its lymphocutaneous presentation, where the infection spreads along the lymphatic vessels, causing skin lesions and lymphadenopathy. The fungus can also affect the lungs and other organs in rare cases, but skin involvement is the most common manifestation.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because sporotrichosis is not typically spread through airborne transmission. The fungus is usually acquired through direct contact with contaminated plant material or soil.
**Option B:** This option is incorrect because the disease is not usually self-limiting and can persist for months or even years if left untreated.
**Option C:** This option is incorrect because the primary mode of transmission is not through contaminated water. While water can be a potential source of infection, it is not the primary route of transmission.
**Clinical Pearl / High-Yield Fact**
Sporotrichosis is often referred to as "rose gardener's disease" due to its association with rose thorns and other plant material. This term can serve as a helpful mnemonic for remembering the common mode of transmission.
**Correct Answer: D.**
