Mycotoxin: Chaetoglobosin A, C
Health Effects: Chaetoglobosins are lethal to mammalian cells due to binding to actin and inhibition of cell division and movement. In one study, injection of Chaetoglobosin A in rodents was fatal at relatively low doses.
C. globosum is a common indoor fungal contaminant of water damaged homes or buildings. It is found on wet drywall, wall-paper, carpets, window frames, and baseboards. Like Stachybotrys, C. globosum spores are relatively large and due to their mode of release are not as easily airborne as are some other molds. Hence, the spore concentration may not be indicative of the severity of the mold contamination, or its production of Chaetoglobosins.
