==Description==

Apergillosis is a disease of the respiratory system caused by several ''[[Aspergillus spp.]]''. ''Aspergillus fumigatus'' is the most frequently reported species in domestic animals but ''[[Aspergillus tereus]]'' has also been implicated. The pathogen is a ubiquitous saprophyte and is found worldwide. Commonly affected species include birds, dogs, cats, horses and cattle but the disease has been reported in many other wild and domestic species. The pathogenesis of the disease remains largely unknown but is thought to be related to the formation of haemorrhagic lesions and enzymatic breakdown of tissue by elastase.
