Pulmonary aspergillosis

Pulmonary aspergillosis is mainly caused by Aspergillus fumigatus, and a few are Aspergillus flavus, Aspergillus flavus, Aspergillus flavus, Aspergillus nidulans, Aspergillus niger and Aspergillus variegata. In China, more than 300 cases of respiratory aspergillus infections were reported successively from 1949 to the end of 1988, but the total number before 1972 was only 47 cases. Pulmonary aspergillosis is mostly a secondary infection, and the primary is extremely rare. Clinically, the disease is generally divided into three types: aspergillus, allergic bronchopulmonary aspergillosis (ABPA), and invasive pulmonary aspergillosis (IPA).
