FOWL TYPHOID AND SIMILAR INFECTIONS 65 
interferes with nutrition. Pigeons, mice and rats proved equally 
refractory. A guinea pig inoculated subcutaneously with duodenal 
contents succumbed to the infection. Rabbits inoculated subcutane- 
ously with culture and fed the same, proved refractory. Intra- 
abdominal inoculation of half a cubic centimeter of culture proved 
fatal to a rabbit. 
Symptoms. Extreme emaciation is the most noticeable symp- 
tom. The appetite is voracious. There is no evidence of diarrhea 
and no increase of temperature. The comb and wattles are slightly 
more pale than normal. 
Morbid anatomy. Autopsy of affected fowls reveals extreme 
emaciation of the muscular system and viscera with almost complete 
absence of fat. There is reddening of the walls of the duodenum 
and the contents are mucoid in appearance. 
Treatment. Dawson recommends purgation to remove the or- 
ganisms in the duodenum. For this purpose he administers castor 
cil in a dose of two teaspoonfuls or calomel in one fourth grain doses 
repeated frequently. He suggests that purgation be followed by a 
stimulating tonic recommended by Mégnin as follows: Powdered 
fennel, anise, coriander seed, cinchona, each 30 grains; powdered 
gentian and ginger, of each 1 dram; powdered sulphate of iron, 
15 grains. Mix. Add from 2 to 4 grains of this mixture for each 
fowl to the food twice a day.
