Experimental cerebral lesions produced by inoculation with Basidiobolus strains.

Two Basidiobolus strains produced progressive chronic granulomatous lesions in the brain following intracerebral inoculation of mice with hyphal material. Large septate hyphal bodies, together with sperical structures and granular material presumed to be of fungal origin, were present in the granuloma tissue surrounding the IIIrd and lateral ventricles. No progressive lesions developed when Basidiobolus mycelium was inoculated at extra-cerebral sites.
