Expectations of efficacy
In consideration of the efficacy expectations for products providing novel and non-chemical helminth control strategies, these products cannot be evaluated using the same criteria as chemical anthelmintics and Ketzis et al. (2006) proposed that evaluation be based on efficacy and economic benefit. After consideration of the published studies, the authors concluded that the use of D. flagrans met the proposed criteria.
In Australia, a field survey of nematophagous fungi by the Australian government science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in 1992-1993 isolated a number of strains of Duddingtonia flagrans and from this collection the strain selected, IAH 1297, had the most suitable characteristics for scale-up and commercial production.
