Abstract: 

Aspergilli cause a variety of health problems ranging from mild allergies to life-threatening systemic mycoses. The incidence of mycoses caused by Aspergillus (aspergilloses) has risen rapidly as chemotherapy, organ transplants and diseases such as AIDS have increased the immunosuppressed population. The most common Aspergillus human pathogens, A. fumigatus, A. flavus, A. niger , and A. terreus, are also the most frequently occurring species in soils, indicating that the clinical population reflects the natural population. About 40 of the 250 species of Aspergillus have been reported as human pathogens. The pathogenic species are not clustered in any one subgeneric taxonomic group. The common trait of most of the pathogenic species is that they grow well at 37 C. Many new species have been described recently based on molecular and physiological data. Some of these are clinically important because they respond differently to therapeutic drugs. The most notable species in this regard is A. lentulus, a sibling species of A. fumigatus.
