霉菌广布于自然界,但致病性霉菌仅10余种,导致霉菌性肺炎的最常见菌群为念珠菌、曲菌、放线菌、新型隐球菌、毛霉菌等。上述菌群除新型隐球菌外多为条件致病菌,其感染常继发于机体抵抗力低下的重症患者或免疫功能低下者,也可发生于应用广谱抗生素后的菌群失调或原有肺部感染性疾病、呼吸道功能减退者。霉菌性肺炎多无特异临床表现,且常被原发病所掩盖,诊断比较困难,其确诊除临床征象外尚须反复多次作痰液检查。现将常见霉菌性肺炎介绍
Mold widely distributed in nature, but only more than 10 kinds of pathogenic mold, resulting in fungal pneumonia is the most common flora Candida, Aspergillus, Actinomyces, Cryptococcus neoformans, Mucor. In addition to the above bacteria outside the new type of cryptococcosis opportunistic pathogens, the infection is often secondary to the body’s resistance in patients with severe or immunocompromised persons can also occur after the application of broad-spectrum antibiotic flora or the original Pulmonary infectious diseases, respiratory dysfunction. Fungal pneumonia more non-specific clinical manifestations, and often covered by the original disease, the diagnosis is more difficult, its diagnosis in addition to clinical signs have to be repeated several times for sputum examination. Common fungal pneumonia will now be introduced
