[Isolation of A. boydii from the soil of the Tadzhik SSR].

The authors present a detailed description of a pathogenic strain of Allescheria boydii Shear, isolated from a soil sample obtained from the karst cave in the vicinity of the Iskan derkerev lake, the Tajik SSR (the morphology of the conidial and ascosporic stages of the fungus, its physiological and biochemical activity and experimental pathogenicity). Data on the existence of this causative agent as a saprophyte in the soil of various continents are also given. A conclusion was drawn that A. boydii was an unpretencious geophilic fungus readily adaptible to the environmental conditions, much more widespread in nature than believed formerly.
