Abstract Relevant literature was reviewed and evaluated. Inhalation of microorganisms may cause non-infectious diseases by activation of immune and non-immune defence mechanisms. The symptoms include allergic alveolitis, fever, chronic inflammatory changes in the airways, mucous membrane irritation, allergic asthma and rhinitis. Inflammatory cells have receptors which recognise and respond to components of microorganisms, such as endotoxin, peptidoglycan, bacterial peptides and fungal glucans. These substances can produce the "toxic" inflammatory reaction which has been reported from many work environments. On repeated intense exposure, the reaction is compounded by immune reactions that result in allergic alveolitis. Immune, non-immune or both types of reaction have been reported from the cotton industry, farming, animal husbandry, grain handling, wood handling, composting and office work (contaminated humidifiers).
