Granular Venereal Disease of Cattle 97 



Thorough disinfection of the stalls and of the diseased and soiled 

 parts of the animals contributes materially to the control of an 

 outbreak and the shortening of its duration. 



The treatment consists of the disinfection of the copulatory 

 organs and those parts which become soiled from the discharges. 

 The choice of a disinfectant is not of essential importance. 

 Thorough mechanical cleansing by washing constitutes a highly 

 important part of the handling. The disinfectants used should 

 constantly be of such a character as to cause little irriation to 

 the highly sensitive parts. One of the chief dangers to be an- 

 ticipated is adhesions between contiguous mucous surfaces of the 

 vagina or of the sheath of the penis. If the walls of the vagina 

 or vulva adhere, because of the denudation of epithelium, breed- 

 ing may be prevented, owing to the narrowing of the canal to 

 such an extent that copulation cannot occur. In the bull, the 

 penis may become adherent to the sheath so that it cannot be 

 protruded, and coition thus be prevented. 



Such untoward results may be best anticipated, and recovery 

 hastened and assured, by douching thoroughly with such mild 

 disinfestants as J^ % solution of carbolic acid, i % alum solution 

 or . I % permanganate of potash, repeated twice daily. The so- 

 lution should be used at about the body temperature and intro- 

 duced into the vagina or sheath by means of an irrigator, until 

 the cavity is^well distended, when it should be allowed to escape. 

 Should the patient give indications, by straining, that the douche 

 is painful, it should be reduced in strength until it is well borne.

In many portions of continental Europe there exists a widely 

 spread and highly contagious venereal disease of cattle, which 

 causes very serious losses in dairies. So far as known, it is purely 

 venereal, transmitted clinically, generally, if not always, by coi- 

 tion, though capable of being transferred by other means.
