1. BACILLUS PARATYPHOSUS B. 



LIKE the paratyphoid A bacillus the paratyphoid B bacillus was first 

 isolated by Schottmuller in 1900-1 from cases of disease in man clinically 

 indistinguishable from enteric fever. 



In England the description " paratyphoid B bacillus " is limited to those 

 strains which in their cultural, agglutination and absorption characteristics 

 are identical with the strain originally isolated by Schottmuller (p. 420). 



The relationship of this bacillus to the other organisms of the Salmonella group has 

 already been discussed (p. 422) and the position may be summarized by stating that 

 in England the following species all identical culturally are distinguished, viz. : 



1. Bacillus paratyphosus B. (Schottmuller).
