APPENDIX 



THE VENEREAL DISEASE OF SHEEP. 



Without having been aware of its existence in America, we 

 have inserted on page io8, a brief description of a venereal dis- 

 ease occuring in sheep in Great Britain. 



According to a recent communication from Mohler of the 

 Bureau of Animal Industry, this venereal disease of sheep pre- 

 vails in certain portions of the sheep raising section of the West, 

 especially in Montana and Wyoming.* His investigations, as yet 

 unpublished, indicate that the bacillus necrophorus is the causa- 

 tive agent, and that the infection may be transmitted to healthy 

 sheep by injecting pure cultures of this organism into the sheath 

 or vulva, if a slight abrasion or catarrhal condition of the mucosa 

 is present. The disease is apparently identical to that described 

 by McFadyean, Flook, and Williams, and is most frequently ob- 

 served in this country during the fall, winter and early spring. 

 It is not uncommonly found to co-exist with similar ulcerations 

 and wart-like crusts on the legs, lips and muzzles of sheep 

 (necrotic dermatitis). The latter affection is known locally as 

 lip and leg ulceration. Bucks with infected lips are said to 

 contaminate the vulvae of ewes by nosing them, and the sheath 

 and penis of the bucks in turn become involved by copulation. 



The treatment will be found very efl&cacious if the disease is 

 handled like contagious abortion. The healthy sheep should be 

 separated from the diseased, and the sheath and vagina irrigated 

 with mild antiseptic solutions, while the external ulcers should 

 be covered with vaseline containing five per cent carbolic acid.
