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.

Aspergillosis in the coral sea fan Gorgonia ventalina. Sea fan coral Gorgonia ventalina, Florida Keys, USA. Depth ~5 metres, showing a lesion surrounded by a band of purple tissue. Central areas of the lesion are devoid of coral tissue revealing the underlying axial skeleton. The purple areas are devoid of coral polyps and result from the increased production of purple sclerites (small, non-fused, carbonate skeletal elements). The purpled area also indicates the location of high fungal hyphal density and el
