Presence of a Parasitic Agent in Various Intracranial Tumours of Man

Abstract

IN a preliminary communication¹, one of us (C. J.) reported how, by following up indications that gliomas of the domestic fowl arise as foci of chronic inflammation and appear to be a response to the presence of some irritant influence, he was led to the demonstration of a parasitic agent associated with the lesions of glioma and encephalitis in this species. Bodies (A, B, C and D) were described and illustrated which were claimed to be phases of a pleomorphic parasite, while others (E) were strongly suspected, and still others considered possibly to represent further phases. In glioma and in chronic disseminated encephalitis, it was the C and D bodies that were especially demonstrated, while the A and B bodies tended to be more characteristic of purulent encephalitis.
