空气中的真菌是变态反应性疾病的重要致敏原，可致过敏性鼻炎，眼病、过敏性哮喘，过敏性肺炎，肠炎、皮肤病等。这些真菌多数为空气中的污染杂菌，一般不致病或为条件致病菌，由于真菌在自然界分布极广，含量很大，孢子体积小，最小的仅为2～3μm，比花粉粒还小，极易在空气中 The fungus in the air is an important allergen for allergic diseases and can cause allergic rhinitis, eye diseases, allergic asthma, allergic pneumonia, enteritis, and skin diseases. Most of these fungi are contaminated bacteria in the air, and they are generally not pathogenic or pathogenic. Because the fungi are widely distributed in nature, the contents are large, and the spores are small in size. The smallest is only 2 to 3 μm, which is more than the pollen grains. Small, easy to be in the air
