    Abstract: In a process for the selection and isolation of predacious fungi for use in the biological control of parasitic nematodes in animals, compost and soil samples are subjected to a multi-step process consisting of 1) a primary stress selection step done in vitro; 2) a secondary stress selection step done in vivo, wherein the fungi which survived the in vitro stress selection step, are selected on the basis of their ability to pass through living animals and 3) isolation of the predacious fungi passing both selection steps and exhibiting a predacious capacity of at least 50% by dung pat assay. These fungi can than be subject to an optional field test experiment. The selected predacious fungi can be administered to the animals as a feed additive or in the form of a device, such as a lick stone or bolus.
