Question
Which one of the following moulds causes mucormycosis, commonly known as 'black fungus'?
The correct answer is
Rhizopus
Identifying the Mould Behind Mucormycosis (Black Fungus)
Mucormycosis, often referred to as the 'black fungus', is a serious opportunistic infection. The question asks to identify the specific type of mould responsible for causing this disease.
Rhizopus: The Primary Culprit
- Rhizopus species are the fungi most commonly associated with mucormycosis. These moulds are widespread in the environment, often found in soil, decaying organic matter, and even on certain foods.
- The infection typically occurs when the spores of Rhizopus are inhaled, ingested, or enter the body through a break in the skin.
- Individuals with weakened immune systems, such as those with uncontrolled diabetes, undergoing chemotherapy, or post-transplant patients, are particularly vulnerable.
Other Fungal Options
- Aspergillus: Causes aspergillosis, a different type of fungal infection.
- Candida: Responsible for candidiasis (yeast infections).
- Histoplasma: Causes histoplasmosis, typically affecting the lungs.
Therefore, Rhizopus is the correct mould identified as the cause of mucormycosis.
