ORGANISMS RESEMBLING THE CHOLERA SPIRILLUM, 

 Spirillum of Finkler-Prior (Vibrio Proteus). 



THIS germ was found in the intestinal discharges of 

 patients sick with cholera nostras. 



Biology and morphology : The Finkler-Prior spirillum re- 

 sembles the cholera organism very closely in contour, but is 

 much shorter and thicker, and it does not form such long 

 chains and spirals. Its ends are pointed and it bulges 

 slightly in the centre. Extending from one end of the

organism is a single flagellum (Fig. 113). The spirillum 

 is exceedingly motile. It does not form spores. The ordi- 

 nary anilin dyes are used in staining. 



It is a facultative anaerobe, growing readily on all culture-
