In vitro stress selection of nematophagous fungi for biocontrol of parasitic nematodes in ruminants.

Laboratory experiments were designed to select nematophagous fungi that were able to survive in vitro conditions simulating passage through the gastro-intestinal tract of cattle. All of the tests were conducted at 39 degrees C. In a primary stress selection step in diluted rumen fluid, 21 isolates were obtained.

Fungal Parasites of the Potato Cyst Nematode Globodera rostochiensis: Isolation and Reinfection.

Fungal parasitism of eggs of the potato cyst nematode Globodera rostochiensis was < 1, 3, and 17% at three sites in Sweden. The fungi isolated most frequently from infected eggs were a Septocylindrium-like fungus ( 19 %), Exophiala spp. (17 %), and Cylindrocarpon spp.

Quantification of predatory and endoparasitic nematophagous fungi in soil.

Methods were developed to quantify predatory and endoparasitic fungi in soil. The methods were based on previously developed detection techniques and combined with a most probable number estimation. The methods were applied to an agricultural soil fertilized with farmyard manure.

Fungal Parasites of the Cereal Cyst Nematode Heterodera avenae in Southern Sweden.

Fungal parasites of the cereal cyst nematode Heterodera avenae were isolated from four sites in southern Sweden. In all, 15 different fungi were isolated from different stages of the nematode life cycle. Among the egg parasites, Verticillium chlamydosporium was common in young cysts on roots, whereas an unidentified species of Verticillium (Verticillium sp.
