The paper summarizes the current state of knowledge regarding the roleof filamentous microorganisms (i.e., fungi and actinomycetes) and their submicrometer propagules (fragments)in formation of indoor bioaerosol. It discusses the importance of water damages in buildings and therole of humidity as a cause of fungal and actinomycetal contamination and subsequent deterioration ofindoor spaces. The importance of the size of airborne microbial propagules for adverse health effectsis broadly commented as well. Regarding the microbial fragments, the method of their release from thecontaminated surfaces (including factors influencing their aerosolization, i.e., air velocity, colonystructure, moisture conditions, vibration of the surface, time factor), modern measurement techniquesand newly obtained results of the immunological reactivity of fragments are discussed. The novel ideasconcerning the dynamic description of the release process of microbial propagules from their sourcesare also presented.
