AMOEBAE OCCURRING IN EXUDATIONS, ABSCESSES, 

 AND IN THE LUNGS. 



IJIMA described amoebae occurring in serous 

 fluid obtained from a woman suffering from peri- 

 tonitis due to an endothelioma, to which he gave the 

 name of Entamceba miurai. He described this 

 organism as measuring from 15 to 18 microns in 

 diameter, and spherical or oval in shape, with a 

 pseudopodium at one end covered with cilia. The 

 cytoplasm is described as finely granular and no dis- 

 tinction was noted between the ectoplasm and endo- 

 plasm. From 1 to 3 nuclei were observed, but no 

 data are given regarding the methods of reproduction. 



It is generally believed that Ijima mistook cells 

 present in the serous exudation for amoeba? and his 

 observations have not been confirmed. I do not be- 

 lieve that Entamceba miurai can be considered a valid 

 species. 



In 1892 Flexner described an amoeba occurring 

 in the pus of an abscess in the oral cavity, and in 

 1893 a similar organism was described by Kartulis 

 in abscesses of the lower jaw, and to this parasite 

 the name Entamoeba kartulm has been given. The 

 description given by Flexner and Kartulis could be
