摘要
Extracellular phospholipase production by environmental and clinical isolates of Aspergillus fumigatus collected from several centres world-wide were compared. All isolates produced extracellular phospholipases which included phospholipase C and a phospholipid acyl hydrolase (phospholipase A and/or phospholipase B) activity. Clinical isolates of A. fumigatus produced the largest zone sizes in a diffusion assay and clinical isolates produced more extracellular phospholipase C than environmental isolates. However, environmental isolates of A. fumigatus showed increased acyl hydrolase activity compared to clinical isolates of A. fumigatus. This study suggests that extracellular phospholipase C activity, but not extracellular acyl hydrolase activity may be important in the pathogenicity of A. fumigatus.
