As regards the reactions of the food poisoning, rat virus, 

 and miscellaneous types above described, the vast majority 

 show no marked variation from the B. type paratyphoid 

 bacilli shown in the table. 



Numbers Fei (b. Gunther Krai.), P47 (b. Danysz from 

 Danysz Virus Oo.) gave slight acidity on salicin after a 

 week. Numbers P29 (b. Gaertner Lenz), P 5 (b. Abel Krai), 

 P 6 5 (b. Hanstedt Krai), Per (b. Kenneth Krai) showed late 

 action on arabinose. This was not affected till after a 

 week (between 7 and 21 days). There were also irregular 

 differences in the amount of motility displayed and in the 

 exact rate of alkalinisation of the litmus milk. 



The indol reaction in all cases was negative by the 

 benzaldehyde method though frequently there was shown 

 a trace of colour by the sulphuric and nitrite method. 



The swine fever cultures while agreeing with the 

 remainder fn all other respects never affected arabinose 

 during the three weeks period of observation. Also it 

 may be added none of these four cultures attacked dulcit 

 under four days, one strain taking over a week (between 

 7 and 21 days).
