36 SPECIAL VETERINARY THERAPY 



Although this disease is supposed to affect turkeys 

 chiefly, it is far more common among chickens than 

 is generally presumed. It can easily be demonstrated 

 by post-mortem examination. 



Whenever the disease has gone through a flock 

 the hen house and all accessories should be thoroughly 

 renovated. If this is not done, isolated cases in an 

 atypical form may make their appearance indefinitely. 



In this as in all contagious or infectious diseases, 

 isolation of the sick helps to curtail the outbreak con- 

 siderably. As soon as a bird shows signs of the di- 

 sease it should be taken out of the flock.
