霉菌在自然界是低等植物中之一大族,已知约8～12万种,共分四大纲:藻状菌纲、子囊菌纲、担子菌纲和半知菌纲。在四大纲中半知菌纲种类最多。因为体积小、孢子繁殖最大,为引起人类过敏最重要的菌类。霉菌引起呼吸道过敏的途径主要是吸入空气中飘散的孢子,而霉菌中含有致敏性的抗原物质。当致敏病人吸入相应的霉菌后,往往引起呼吸道过敏症状如过敏性鼻炎、支气管哮喘等。因此,探明空气中飘散的霉菌种类及数量分布,对指导过敏病人的诊断与治疗有重要意义。
Mold in nature is one of the lower plants, known about 8 to 120,000 species, is divided into four groups: algae spermatophyte, Ascomycota, Basidiomycetes and semi-know Mycobacterium. In the four programs in the most known type of fungi. Because of its small size, spores reproduce the most, causing the most important human allergy bacteria. The main cause of respiratory tract allergy caused by fungal inhalation of spores in the air, while the mold contains allergenic antigen. When the sensitized patient inhaled the corresponding mold, often cause respiratory allergies such as allergic rhinitis, bronchial asthma and so on. Therefore, it is important for the diagnosis and treatment of allergic patients to detect the type and quantity distribution of mold in the air.
