Aspergillus deflectus is an aspergillus mold that does not do well in indoor environments. It has been actually premodinantly isolated from tropical and subtropical soils. Colony characteristics of this species are mouse-grey in color and has very restricted growth.
Aspergillus deflectus is found to be allergenic and occasionally pathogenic. While there are no health issues associated with this type of aspergillus mold on humans, several cases of disseminated aspergillosis, particularly mycosis, in dogs were reported in Australia and in the West Coast of the USA. Although not considered to be hazardous to humans, it is still advised to take certain precautions when handling this kind of mold so as to prevent acquiring diseases that might be induced by A. deflectus.
