在免疫损伤患者中,真菌引起的感染仍然是导致发病和死亡的一个主要原因。在真菌性感染中,虽然白色念珠菌和曲霉菌是最常分离到的病原菌,但其他少见的真菌,诸如链孢霉菌(Alternaria)已被人们检出。链孢霉菌是一种条件致病菌,可引起轻微的临床症状。作者于1974～1989年观察了1186例连续进行骨髓移植的患者,其中129例(占11%)发生的真菌感染不是由白色念珠菌所致。这129例中有6例(占5%)为链孢霉菌引起的局部侵袭性鼻窦感染。其特征是,临 In immunocompromised patients, infections caused by fungi are still a leading cause of morbidity and mortality. In fungal infections, while Candida albicans and Aspergillus are the most commonly isolated pathogens, other rare fungi, such as Alternaria, have been detected. Streptomyces is a pathogenic bacterium that causes mild clinical symptoms. The authors looked at 1,166 consecutive patients who underwent bone marrow transplantation between 1974 and 1989, of which 129 (11%) had fungal infections not caused by Candida albicans. Six of these 129 (5%) were locally invasive sinus infections caused by Neurosporidium. Its characteristics are, Pro
