338 Suppuration 



Entamoeba histolytica {q.v.) is, to all appearances, the sole excitant 

 of the abscesses of the liver secondary to dysentery. It is true that 

 these are cold abscesses and necrotic rather than distinctly purulent 

 in character, yet it seems best to speak of the organism in this 

 connection. 



Entamceba buccalis (Prowazek*) is a small ameba that has been 

 found in purulent exudates in the oral tissues of persons with carious 

 teeth. It is at present thought to be the cause of Riggs' disease or 

 pyorrhea alveolaris. 



Amoeba kartulisi (Dofleinf) appears to be capable of exciting 

 suppuration. It was found by Kartulis in the pus from an abscess 

 of the right side of the lower jaw. The patient was a man aged 

 forty- three years who had been operated upon for the removal of a 

 piece of bone. It is 30 to 38 /x in diameter, is actively motile. Its 

 coarse protoplasm contains red and white blood-corpuscles. Kar- 

 tuUst found the same organism five times in other cases, and 

 Flexner§ found it also. 



Amoeba mortinataUum, described by Smith and Weidman,|| 

 was found in distributed small purulent foci in the kidneys and 

 other organs of a still-born fetus.

Before leaving the subject, attention must be directed to other 

 bacteria that under exceptional circumstances become the cause of 

 suppuration. Among these are the pneumococcus of Frankel and 

 Weichselbaum, the typhoid baciUus, and the Bacillus coli communis. 

 These organisms are considered under separate and appropriate 

 headings, to which the reader is advised to refer.
