Endolimax kueneni n.sp., Parasitic in the Intestinal Tract of the Monkey Macacus cynomolgus

Abstract

This amoeba was found in the large intestine of a Macacus cynomolgus, that was killed because it suffered from paralysis of the hind legs and emaciation. The autopsy showed these symptoms to be dependent on a general tuberculosis, in which, besides many other organs, the spinal matter was involved. Microscopic examination of the intestinal contents revealed the presence of motile amoebae and cysts. Except some small tubercular foci in the serosa no pathological lesions could be detected in the intestine. Close examination of the mucosa failed to reveal any ulceration; blood and mucus were totally absent.
