CHAPTER IX 



Tuberculosis 



Tuberculosis in fowls has long been a serious pest in 

 Euorpe. Ziirn in his "Krankheiten des Hausgefliigels," 

 published in 1882, devotes several pages to the description 

 of this disease as it occurred in Germany, Its appearance in 

 this country, however, seems to have been much more recent. 



Salmon, whose book was published about 1888, says that 

 the disease " is by no means rare in the United States if the 

 statements of our professional men are to be accepted." 

 However, at that time very little had been done in the way of 

 bacteriological diagnosis and no doubt many of the early 

 reports were unreliable. 



The disease was first reported on the basis of bacterio- 

 logical examination in 1900 by Pernot.'^ In 1903 Moore 

 and Ward ^ reported investigations on avian tuberculosis in 

 California. They found "a number of flocks in which the 

 mortality from the disease was very high." Fowl tuber- 

 culosis was reported from western and central Canada in 

 1904 by Dr. C. H. Higgins.^ In 1906 it was reported from 

 New York and in 1907 from southern Michigan. The
