  There is a large presence of microorganisms in the lungs known as the lung microbiota that interacts with the airway epithelial cells; an interaction of probable importance in maintaining homeostasis. The microbiota is complex and dynamic in healthy people, and altered in diseases such as asthma and COPD. For example significant changes can take place in COPD following infection with rhinovirus. Fungal genera that are commonly found as mycobiota in the microbiota include Candida, Malassezia, Saccharomyces, and Aspergillus.
