Il6 SPIROCH^ETES. 



lived a little while in broth : he also noted that the more 

 cholera-vibrios there were present, the fewer were 

 the spirilla, and vice versa. 



Le Dantec found spirilla in the stools of certain pa- 

 tients suffering from dysentery. 



Werner found in the human alimentary canal two 

 forms of spirochaetes one with long undulations, 4 . 6 

 to 7 . 3/1 in length, which may occur in masses (this form 

 is not identical with any of the mouth-spirochsetes) ; and 

 a second, with finer curls, 3.5 to 6 . i/i in length, resem- 

 bling Sp. dentium. The former he calls Sp. eurogyrata 

 and the latter, Sp. stenogyrata. 



Smith (Theobald) found spirilla along with comma 

 bacilli (vibrios) in the intestines of pigs ; they had two 

 to three curls, with a wave-length of 2//. He could 

 not cultivate them. 



Novy and Knapp found spirilla (Spirillum glossince) 

 in the stomach of the tse-tse fly; short forms measured 

 8/z in length and long ones 1 5^. The spirilla were shorter, 

 narrower, and more closely curled than Sp. obermeieri. 

 They multiplied by transverse division, the long 

 forms probably being about to divide (see also page 

 68). 



Mezinescu found spirilla in the pus from a case of 

 calculous pyelitis ; they were from 3.6 to 8// long, rarely 

 attaining a length of 10 or i2/x. Doerr found spirilla 

 in the pleural and pericardial fluid of a syphilitic sub- 

 ject and thinks they may have been the same as those 

 described by Mezinescu.
