Molecular analysis of certain isolates of Serpula lacrymans

Abstract

A range of isolates of Serpula lacrymans show identical molecular profiles by Western Blotting or lectin staining. One isolate, BF-050, showed differences in silver stained protein profiles from old mycelium but profiles from young mycelium of BF-050 were identical to the type strain of S. lacrymans FPRL 12C. Both S. lacrymans and the related organism, Serpula himantoides, shared different profiles for old and young mycelium confirming that growth phase antigens/proteins are not limited to S. lacrymans. Lectin staining profiles could distinguish between S. lacrymans FPRL 12C, BF-015B, S. himantoides and all other basidiomycete organisms tested. Differences between strains of S. lacrymans including BF-050, were not apparent.
