Aspergillus accounts for a significant number of fungal species for microfungi. While colours of the fungus varies accordingly to its species, growths on agar for the study shows a light green colony center with white edges.
Features
Cladosporium is a fungus with dark-pigmented conidiophores and conidia. Similar to curvularia, spores sprout direct from the short conidiophores, which are located at apically and laterally of hyphae. The conidia are 1 to 2-celled, with the shape ranging from round to oval. Lemon-shaped conidia are also characteristic of Cladosporium spores.

|
| Observed Spores Growth |
- At tip (Apical) and side (Lateral)

Allergenic Diseases
|
Affected Areas
|
Forms/ Medical Terms
|
Descriptions
|
|
Airway to Lungs (Bronchial Tubes)
|
Asthma
|
- Inflammation and constriction of airway to lung
|
|
Eyes
|
Allergic Rhinitis
|
- Occurs when allergens trigger release of histamine, causing inflammation and fluid production in linings of nasal passages, sinuses, and eyelids
- Reactions include sneezing, congestion, runny nose, itchy nose, throat, eyes, and ears
|
|
Throat
|
|
Nose
|
|
Allergic Fungal Sinusitis (AFS)
|
- Occurs in individuals with a background of asthma and rhinitis
- Does not invade tissue; fills up sinus with substances of membrane cells, decomposing white blood cells and fungal hyphae
- Built-up pressure in the sinus can eventually cause expansion and erosion of the sinus walls
