Pulmonary aspergillosis (cow 2). Section of lung from a 2 year old cow with weight loss and anorexia since calving. On necropsy examination, multiple firm masses were identified throughout the lungs. These were cavitating in nature, with a necrotic centre and peripheral fibrosis. Both this section and the following one are taken from the edge of such a lesion and demonstrate the pyogranulomatous inflammatory response.
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.
