Notes:
Confocal scanning laser microscopy – (CLSM). CAAF stained showing the hyphal network in contact with extracellular matrix. The polysaccharides of the ECM and fungal cell walls were stained by CAAF (concanavalin A-Alexa Fluor 488 conjugate).
These colonies were isolated from a BAL, (also with bacterial qrowth of S.aureus and S.maltophilia) from a patient with a VAP (undergoing corticosteroid treatment). The growth medium used is sabouraud dextrose agar , incubated at 37° C
The identification is made by microscopic/macroscopic observation criteria.
Microscopic morphology of A. flavus. Conidial heads are radiate, splitting to form loose columns, biseriate but having some heads with phialides borne directly on the vesicle.
