Species In Flemming, D.O., and Hunt, D.L. In humans, the major forms of disease are:[29][30], Fungal infections from Aspergillus spores remain one theory of sickness and untimely death of some early Egyptologists and tomb explorers. These mycotoxins produced are called aflatoxins; they are not constantly produced but can be triggered to do so by factors including stress of the organism. The simultaneous publication of three Aspergillus genome manuscripts in Nature in December 2005 established the genus as the leading filamentous fungal genus for comparative genomic studies. (1996). ), [26], Genome sizes for sequenced species of Aspergillus range from about 29.3 Mb for A. fumigatus to 37.1 Mb for A. oryzae, while the numbers of predicted genes vary from about 9926 for A. fumigatus to about 12,071 for A. oryzae.
