Abstract

Summary

  • 1.  The chorio-allantoic membrane of the developing chick was successfully inoculated with a seven year old culture of .
  • 2.  Eggs were incubated 12 days and observed 6 days after inoculation.
  • 3.  The macroscopic appearance of the lesion showed a thickened, yellowish-gray plaque with a peripheral opaque region.
  • 4.  Microscopically, there was a marked reaction in the ectoderm, mesoderm, and the underlying entoderm.
  • 5.  The cellular response consisted of the appearance of large numbers of fibroblasts, monocytes, leucocytes, red blood cells with a marked eosinophilia.
  • 6.  The organism showed a conversion into yeastlike cells analogous to the formation of arthrospores and oidia.
  • 7.  The ascus-like cells, stalagmospores or aleuriospores became converted into many yeastlike cells which seemed to indicate that they are most likely ascus-like structures, probably of a degenerate nature.
