Eesults : 



The rooster died in 9 days. P.M. positive. 

 The rabbit died in 17 days. P.M. positive. 

 The guinea pig and the rats remained alive. 

 A little of the mashed liver of No. 3 fowl was given as food 

 to 2 young rabbits, 3 rats, and 1 guinea pig. 



Results : — 



1 rabbit died in 6 days. P.M. positive. 

 The other rabbit, together with the rats and the guinea 

 pig, remained alive. 

 A Broth Culture inoculated from the rabbit's liver gave 

 positive results. A little of this broth culture was injected into 

 a pullet, a rabbit, a rat, and a guinea pig. 



Results : — 



The pullet sickened on the 6th day. but gradually 



recovered. 

 The rabbit appeared sick on the 4th day, became weaker 



on the 5th, and died on the 6th day after inoculation. 

 Post mortem and microscopical examination gave positive 



results. 

 The rat and the guinea pig remained alive. 



INOCULATION AND FEEDING EXPERIMENTS 



To Show the Difference in the Susceptibility of Rabbits 

 TO Fowl Enteritis and Fowl Cholera. 



For this experiment 4 healthy and vigorous rabbits were 

 selected. Inoculated one rabbit and fed another with a mere 

 trace of a 24 hours old broth culture of the bacteria of chicken 

 cholera. 



Results : — 



The inoculated rabbit died in 14 hours and the fed one 

 in 17 hours. P.M. in both cases positive. 



Microscopical examination of the blood from the liver 

 showed enormous numbers of the specific bacteria. 

 Inoculated one rabbit and fed another with a mere trace of 

 a 24 hours old broth culture of the bacteria of " fowl enteritis."
