概述病原:曲菌属丝状霉菌,其中致病性较强的有薰烟色曲菌、黄曲菌、黑曲菌等。曲菌孢子存在空气中,尤以秋冬及阴雨季节,谷物、稻草发霉时更多。曲菌虽在自然界分布很广,但系寄生菌,多不致病,仅当呼吸道有炎症或机体免疫力低下时,吸入大量曲菌或口咽腔原有的曲菌大量繁殖,才能引起感染,故称为条件致病菌或机遇感染。发病情况:过去认为曲菌病较为少见,近年发现发病率有所增加。霉菌病的增加与使用抗菌素、激素、细胞毒性药物有密切关系。抗菌素引起菌群失调,促进霉菌繁殖;激素为强有力的免疫抑制剂,能使淋巴细胞溶 Overview Pathogen: Aspergillus filamentous mold, which is highly pathogenic smoked fungus, Aspergillus flavus, Aspergillus, and so on. Aspergillus spores exist in the air, especially in autumn and winter and the rainy season, grains, straw moldy more. Aspergillus is widely distributed in nature, but Department of parasites, and more non-pathogenic, only when the respiratory tract inflammation or the body immunity is low, the inhalation of a large number of Aspergillus oropharyngeal original Aspergillus multiply, can cause infection , So called opportunistic pathogens or opportunistic infections. Morbidity: In the past that aspergillosis is relatively rare, in recent years found that the incidence has increased. Mycosis increased with the use of antibiotics, hormones, cytotoxic drugs are closely related. Antibiotics cause flora and promote mold reproduction; hormones as a powerful immunosuppressive agent, can make lymphocyte lyse
