摘要

In response to a request from the Centers for Disease Control and Prevention,National Center for Environmental Health, the presence of Stachybotrys-atra fungi and associated mycotoxins was assessed in 42 homes in the Cleveland, Ohio area to support an investigation of acute pulmonary hemorrhage (hemosiderosis) among infants in this area. Air, bulk, and surface samples were obtained from homes with cases of hemosiderosis and homes without such cases. Mean levels of total fungi were higher in homes with hemosiderosis cases without such cases. Mean levels of total fungi were higher in homes with hemosiderosis cases had higher levels of Aspergillus and Cladosporium fungi compared with homes with cases. In contrast, S-atra fungi were much more abundant in homes with cases of hemosiderosis. The mean concentration of S-atra in surface samples was significantly higher in homes with cases compared with those without. The authors conclude that homes with infants with hemosiderosis had higher concentrations of total fungi and S-atra than homes without.
