Summary and Conclusions

  • 1.  As and occurred together in 20 times as many appendices as theoretically expected, it indicated some connection between the two species.
  • 2.  Sections of pinworms from a -harboring appendix revealed the presence in many eggs of small, ameboid, uninucleate organisms, whose nuclei greatly resembled those found in uni- and binucleate from the lumen of formalin-fixed appendices. These bodies were not found in pinworm eggs from cases not known to harbor . Therefore, the pinworm appears to be a vector of .
  • 3.  Indirect evidence of transmission of in pinworm eggs is presented, but efforts to culture the ameba from eggs have not yet been successful.
  • 4.  Further evidence linking with , the flagellate which causes blackhead in turkeys, is presented. This tends to confirm Dobell's hypothesis that is actually an aberrant flagellate rather than a true ameba and that its present classification is an error.
