Types of Mould

Mould is ubiquitous and can grow anywhere there is moisture and dust (source of food). There are approximately 6000 to 10,000 genes identified in fungi. Most fungi do not affect human health. However, there are at least 189 types that have been identified as fungal allergens and a few genera such as Aspergillus, Penicillium, and Cladosporium have been well-characterized.
