Article on Avian Aspergillosis from Allison German in the new Veterinary section:


No abstract. First paragraph: The agent and the environment Aspergillus fumigatus is an opportunistic, ubiquitous soil saprophyte. It is a mycelium-forming true fungus, classified as an Ascomycete, capable of asexual reproduction. The fungus may be found as a contaminant of animal feeds, straw or rotting plant or animal matter, with growth promoted by poor hygiene. Inadequate ventilation and dusty environments increase the risk of exposure (Oglesbee, 1997). An example of the importance of poultry litter as a source and predisposing cause of Aspergillus spp. is given by Huton (1966). Forbes (1990) describes an increase in incidence in aspergillosis in a raptor collection due to the use of contaminated shredded wood bark.
