Abstract

Aspergillus spp. are prevalent in the environment and commonly isolated from soil.  Microscopic characteristics of the genus are mainly defined by the aspergillum-like conidia bearing structure or conidial head. In most cases this structure is essential for rapid and quick identification in the laboratory especially for detection of Aspergillus spp. that are known to be clinically important. In the present study, several Aspergillus spp. isolated from beach sand were microscopically identified based on the characteristics of the conidial head and conidia of which seven species were identified. Microscopic observation was done using a light microscope and scanning electron microscope. The species were identified as A. aculeatus, A. carbonarius, A. niger, A. flavus, A. tamarii, A. terreus and A. sydowii. The results showed the characteristics of conidial head and the shape of conidia can be used as preliminary identification of Aspergillus spp. to sort the species into sections as well as to species levels for certain species.

Keywords: Aspergillus, scanning electron microscopy, light microscope,  beach sand.
