GENERAL CHARACTERS OF SPIROCH^ETES. 59 



in noma or gangrene of the cheek, in hospital gangrene, 

 etc.). Uffenheimer thinks the spirochaetes are the 

 pathogenic agents in Vincent's angina, as, if the tonsils 

 are removed in cases in which these organisms are 

 present, further ulceration occurs. Ellermann also 

 points out that the spirochaetes are found more deeply 

 situated in the tissues in cases of noma than are the 

 bacteria, and that they seem to prepare the way for 

 the latter. The relationship between the spirochaetes 

 and the fusiform bacilli has already been discussed 

 (page 43). Veszpr&ni thinks that the spirochaete of 

 Vincent's angina is identical with the common spiro- 

 chaete of the mouth, Sp. buccalis. 



OTHER DISEASES IN MAN. 



Moritz found spirochaetes in the bone-narrow and in 

 the muscular coat of the intestine in a man who died 

 with symptoms of intense anaemia, fever and diarrhoea, 

 and in whom there were found after death an ulcer of 

 the stomach and miliary nodules of new growth (en- 

 dothelioma?) in the lungs. The primary seat of the 

 tumour was not discovered. The spleen was enlarged. 

 He thinks the spirochaetes in this case were different 

 from any previously described species, but their nature 

 and relation to the disease must remain problematical. 



Castellani found spirochaetes present in certain cases 

 of haemorrhagic bronchitis (Sp. bronchialis) . He believes 

 that they may be the cause of the disease. 



Waters also noted spirochaetes in a series of cases of 

 bronchitis, without haemoptysis. Branch found or- 

 ganisms of this nature in a case of pulmonary tuber- 

 culosis, in which they were present in the expectora- 

 tion along with tubercle bacilli; they may have been 

 derived from the mouth.
