近年来，深部真菌感染率正在上升，感染菌种也多种多样。假丝醇母是最常见的病原菌，其中又以白假丝酵母最为多见，曲霉、隐球酵母等也是常见的病原菌。病原菌侵犯人体，可累及各系统、器官及组织，甚至引起败血症．其中，呼吸道感染较常见．除自身免疫力下降外，外伤、用药、手术操作、导管植人等外源性因素也是深部真菌感染的危险因素．人类免疫缺陷病毒感染、血液病、恶性肿瘤、器官移植等患者更易发生深部真菌感染。深部真菌感染对患者的健康与生命构成严重威胁，临床医生必须于以足够重视，注意合理用药、合理操作、密切观察、及时诊断、尽早治疗，以挽救患者生命。
In recent years, the rate of deep fungal infections is on the rise, with a wide variety of infectious species. Filament alcohol mother is the most common pathogen, which is the most common Candida albicans, Aspergillus, Cryptococcus is also a common pathogen. Pathogens invade the human body, can affect various systems, organs and tissues, and even cause sepsis. Among them, respiratory infections are more common. In addition to decreased immunity, exogenous factors such as trauma, medication, surgical procedures and catheterization are also risk factors for deep fungal infections. Deep fungal infections are more likely to occur in patients with human immunodeficiency virus infections, blood diseases, malignancies, and organ transplants. Deep fungal infection poses a serious threat to the health and life of patients. Clinicians must treat them with enough attention, pay attention to rational use of drugs, rational operation, close observation, timely diagnosis and early treatment to save their lives.
