194 BACTERIOLOGY. 



patches and thence into the mesenteric glands 

 and the spleen. They are found in the rose- 

 spots on the abdomen, but the circulating 

 blood is usually free from them. They may 

 induce also broncho-pneumonia, meningitis, 

 myocarditis, orchitis, and especially suppura- 

 tions such as otitis, periostitis, peritonitis and 

 empyema. They may also produce inflamma- 

 tion of the kidneys, and I have cultivated 

 them from the urine during life in cases where 

 albuminuria occurs, while A. Pfeifferhas culti- 

 vated them from the diarrhceal stools, where 

 they generally appear only after the first week 

 of the disease. 



The " true " colon bacteria have been re- 

 peatedly observed in pneumonia in children 

 and also in inflammatory processes in the in- 

 testine, especially in inflammation of the ap- 

 pendix and in perforation-peritonitis ; also in 

 otitis, puerperal fever, and more often, in in- 

 flammations of the bladder when inflammation 

 ascending to the kidney may be induced. 



The typhoid bacteria have been found in the 

 water of wells, especially in the slime at the 

 bottom, and once also they have been found in 

 soil ; the colon bacteria are often found in pol- 

 luted water. 



In cases of meat-poisoning, bacteria are usu- 

 ally found which bear a striking resemblance
