Characteristics of the organisms
Aspergillus spp. (53%) were the commonest species isolated among the
studies (Table 1). In terms of specific organism, Aspergillus niger,
Candida albicans, Aspergillus flavus and Aspergillus fumigatus were
found in 53%, 41%, 33% and 31% of studies respectively. At least one
Aspergillus organism was routinely isolated in studies involving
immunocompromised patients. Opportunistic organisms were isolated in
immunocompetent patients in two studies: a case of external ear
mucormycosis was reported in India and a case of otomycosis caused by
Pseudallescheria apiosperma was reported in Tunisia.
