Abstract
Aspergillus species (spp.) are medically important pathogens that cause aspergillosis, and A. fumigatus is the most prevalent causative agent of the disease. Aspergillus spp. produce various secondary metabolites; however, the role of these metabolites in aspergillosis remains unclear. Gliotoxin is a major secondary metabolite produced by A. fumigatus. Several recent studies have reported that gliotoxin contributes to the virulence of A. fumigatus. Here I review studies related to gliotoxin and its contribution to the infection caused by A. fumigatus.
