因职业性接触而吸入某些抗原引起的一组肺部变态反应性疾病统称为外源性过敏性肺泡炎,蘑菇肺即属其中之一。随着蘑菇培植增长和接触人群的增加,该种致病性抗原越来越引起人们的注意。 1.病因与发病机理蘑菇肺的发生主要由于在蘑菇栽培中大量真菌类孢子被人体吸入,菌孢子来源之一是在高温堆肥时(40～60℃)所产生的大量嗜热放线菌,它们能产生大量孢子,孢子很小,直径约为1微米左右,广泛存在蘑菇培育室中。再者,是在蘑菇
A group of lung allergic diseases caused by inhalation of certain antigens due to occupational exposure are collectively referred to as extrinsic alveolar alveolitis. Mushroom lungs are one of them. With the growth of mushroom cultivation and the increase of people exposed to the disease, the pathogenic antigen attracts more and more attention. 1. Etiology and pathogenesis The occurrence of mushroom lung is mainly due to a large number of fungal spores inhaled in the mushroom cultivation, one source of spores is a large number of thermophilic actinomycetes in the high temperature composting (40 ~ 60 ℃) They can produce a large number of spores, spores are small, about 1 micron in diameter, widespread in mushroom cultivation room. Again, it’s mushrooms
