A MANUAL OF BACTERIOLOGY 



Under " Paratyphoid Fevers," p. 436, reference has been made 

 to a paratyphoid C bacillus. Hirschf eld's aertrycke strain (see 

 above) was named by him para C. The same name was, however, 

 previously applied to an organism described by Uhlenhuth in 1908, 

 belonging to this group, but apparently causing only gastro- 

 enteritis in man and not an enteric-like disease. It would seem 

 better, therefore, to reserve the name para C bacillus for Hirsch- 

 feld's organism. It was pointed out (p. 436) that the B. para- 

 typhosus A is more akin to the typhoid bacillus than the B. para 

 typhosus B, which is nearer to the Gartner bacillus, and the 

 para B. bacillus seems capable of producing gastro -enteritis as 

 well as paratyphoid fever. 



The Paratyphoid-Gartner group may be subdivided as follows 

 on the basis of fermentive power : 



The Gartner group of organisms has been termed the Salmonella 

 group, and the relationship of the various types is represented 

 diagrammatically as follows by Schiitze : l 



Salmonella Group. 



B. enteritidis 

 (Gartner). 



B. paratyphosus C 

 (Uhlenhuth). 



Schottmiiller 

 type (F & G).* 



Hirschfeld 

 type (F).f 



Multon 

 type (G). 



Stanley 

 type (F & G). 



Etc. 



* Prototype : B. paratyphosus B of Schottmiiller. 



t Prototype : B. paratyphosus C of Hirschfeld, MacAdain, etc. 



F = Known to cause continued fever in man. 



G = Known to cause gastro-enteritis in man.
