Aspergillus fumigatus in Poultry
Aspergillus fumigatus remains a major respiratory pathogen in birds. In poultry, infection by A. fumigatus may induce significant economic losses particularly in turkey production. A. fumigatus develops and sporulates easily in poor quality bedding or contaminated feedstuffs in indoor farm environments. Inadequate ventilation and dusty conditions increase the risk of bird exposure to aerosolize...
متن کاملHumic acid as a feed additive in poultry diets: a review
Many studies tested different feed additives, among these additives, humic substances (HS) have been used in livestock and poultry diets. Humic substances commonly present in nature as they are created from the organic matter decomposition, and are normally found in the soil and natural water. Active components of HS consist of humic acid (HA), humus, ulmic acid, fulvic acid, humin and certain ...
متن کاملExtracellular proteinases of Aspergillus oryzae.
Although the production of proteolytic enzymes by different strains of Aspergillus oryzae has been investigated in submerged culture (5, 15), in static liquid culture (3, 11), and on solid substratum (8-10), there appear to be few reports pertaining to the comparative evaluation of these different methods on the elaboration of proteinases by specific strains of A. oryzae. K. Mogi (13) compared ...

Bacteriol. 91:1883-1887. 1966.-Trehalases (soluble trehalase and coat-bound trehalase) were found in the conidia of Aspergillus oryzae, and the total activity of the trehalases increased during the germination process. The soluble trehala...
متن کاملCyclopiazonic Acid Biosynthesis of Aspergillus flavus and Aspergillus oryzae
Cyclopiazonic acid (CPA) is an indole-tetramic acid neurotoxin produced by some of the same strains of A. flavus that produce aflatoxins and by some Aspergillus oryzae strains. Despite its discovery 40 years ago, few reviews of its toxicity and biosynthesis have been reported. This review examines what is currently known about the toxicity of CPA to animals and humans, both by itself or in comb...
