Penetration of ovicidal fungus Verticillium chlamydosporium through the Ascaris lumbricoides egg-shells.

Abstract:

:The course of penetration of the ovicidal fungus Verticillium chlamydosporium Goddard through the Ascaris lumbricoides egg-shells was studied in electron miorographs. The contact area between the egg and the fungus is smooth at the stage of the contact of the ovicidal fungus with the egg surface, as well as at the stage of adhesion. No special attaching organs are formed which indicates that no mechanical penetration of the fungal hypha through the egg-shells is involved. Traces of enzymatical activity of the fungus penetrating upright through the egg-shells can be observed during the penetration stage proper. At the consumption stage, the branching of the ovicidal fungus becomes more dense and some hyphae grow through the egg envelopes parallelly under the egg surface. The fungus grows through all parts of the infected egg, even through its contents.
