72 FOWL CHOLERA 



duced a successful treatment. In order to study the horrible microbe, 

 the illustrious professor made a "bouillon" with the muscular tissue of a 

 hen and water. He dropped in it a drop of blood taken from a diseased 

 living fowl. He left the whole exposed to the surrounding air for a period 

 of time depending on the noctivity of the virus he wished to obtain. After 

 six or seven months he thus obtained a virus to such an extent attenuated 

 that by inocculating or vaccinating with this product, he was able to cause 

 a mild form of the disease which generally immunized the fowls against the 

 deadly infection. 



Fowl cholera is thus no longer a cause of dread and horror, and we may 

 look with confidence to the future. 



Under the influence of the pasteurian treatment the incipient diarrhea 

 is arrested, torpor disappears and life seems to return. The improvement 

 is persistent and lasting. After a short time, the animals run around, 

 scratch and pick; the comb resumes its shape and color; the eye is 

 bright; the animals become lively again and are heard once more; they 

 cackle and crow, they hunt their food with a renewal of vigor and life. 

 There is a complete and sure return to a condition of perfect health. 



It has been recommended to give those animals which are not infected, 

 plenty of green food, and grape marc when in season. 



The manure should be carted away, and the poultry house or pen 

 properly cleaned and washed with a solution of one per thousand of sul- 

 phuric acid, which kills the bacillus. The animals may be brought together 

 again : 



1 If the isolation has been sufficient. 



2 If there are no more diseased birds. 



3 If the hens and poultry in general are kept separate from the other 

 animals on the farm. 



To protect their birds and animals against those two most deadly 

 plagues, cholera and anthrax, breeders should have their fowls vaccinated 

 with the Pasteur refractory bouillon. 



Diseases of poultry are nearly always the result of bad food, filth in 

 the drinking water, or infection of the ground and houses; consequently 

 the best and most successful remedies are, good food, water renewed daily 

 and kept fresh and clean, and in general proper attention to cleanliness 

 of the poultry house and pen.
