Loss of virulence of the endoparasitic fungus Drechmeria coniospora in culture

Parasitic fungi in culture frequently lose pathogenicity. For example, the virulence of certain entomogenous fungi decreases during in vitro culture over long time periods. Management of plant-parasitic nematodes through natural enemies is an active research area. Since many of the efficient nematod...

Description
Summary:Parasitic fungi in culture frequently lose pathogenicity. For example, the virulence of certain entomogenous fungi decreases during in vitro culture over long time periods. Management of plant-parasitic nematodes through natural enemies is an active research area. Since many of the efficient nematode antagonists are obligate parasites, knowledge of their behavior under laboratory conditions is required. Previously, Drechmeria coniospora was reported to infect Meloidogyne incognita and two other plant-parasitic nematode species. This is a report of the loss of pathogenicity of isolates of D. coniospora and on studies investigating this phenomenon.
