[Diseases associated with organic dusts].

Organic dust is ubiquitous and is a mixture of both allergens and several pro-inflammatory agents. Exposure to organic dust elicits a very complex immune response leading to pulmonary and systemic symptoms, in some occupational settings as well as in domestic environment. In this later setting, identification of pathogenic components from the organic dust could improve our understanding of pathogenesis of asthma as well as chronic obstructive pulmonary diseases.
