Question
**Question 2: Understanding Diseases Caused by Aspergillus sp.**

1. **What disease can be caused by Aspergillus sp.?**

   Aspergillus species can cause a disease known as aspergillosis. This condition can manifest in several forms, including allergic reactions, infections in the lungs, and infection spread to other organs.

2. **What part of the body is affected?**

   Aspergillosis typically affects the respiratory system, particularly the lungs. However, it can also spread to other parts of the body, including the sinuses, skin, and in severe cases, organs like the brain or kidneys if the infection disseminates.

3. **How is the disease transmitted?**

   Aspergillosis is primarily transmitted through the inhalation of fungal spores. These spores are commonly found in the environment, especially in soil, decaying vegetation, and dust, making it difficult to avoid exposure entirely. Individuals with weakened immune systems or underlying lung conditions are more susceptible to infection.

Step 1: Aspergillus

Aspergillus is a genus of moulds in the Ascomycota division. They are asexual spore-forming genera with a high aerobic capacity. Conidiophore is the asexual spore-forming body. Some of the species, however, have been reported to have a sexual state.

The most common species of the genera, Aspergillus niger, is a major source of citric acid and enzymes such as lactase, glucose oxidase, and lysozyme.
