Symptoms, Course, Diagnosis, Treatment. 359 



The neighboring lymph glands may suppurate, leading to 

 abscess formation in the vicinity of the anus and in the groins ; 

 exceptionally such may also occur in the tissue of the udder. 

 At the same time the gait is stiff, sensibility is greatly depressed, 

 the appetite impaired, the body temperature increased, and the 

 fever may be remittent. Finally pyemia or septicemia with 

 their usual severe results may follow the local affection through 

 the development of a general infection. 



Course. In the great majority of cases the disease runs a 

 course of 2, more rarely of 3 to 4 weeks, and terminates in com- 

 plete recovery. The severe cases may always be traced to a 

 subsequent septic infection, or to traumatic influences ; in such 

 cases the infection may be so intense, and the changes in the 

 tissue so severe, that convalescence may extend to several 

 months ; sometimes entire recovery fails to follow or the disease 

 may terminate in death. Although even larger wounds may 

 heal without scar formation, in some cases a chronic vaginal 

 catarrh follows, which may result in sterility of itself, or through 

 an extension to the uterus. In bulls the deep penetrating abscess 

 formation may result in a deformity of the penis (Kampmann), 

 or a weakness of the penis remains, which prevents the animals 

 from the act of coitus. 



Diagnosis. The thin walled vesicles on the genital organs 

 assure the diagnosis, and distinguish the disease from the other 

 inflammatory local affections. If ulcers have already developed 

 from the vesicles, it can be distinguished from traumatic inflam- 

 mation only by. its infectious nature, and by the rapid recovery. 

 In infectious vaginitis of cattle, with which this disease has 

 been frequently confounded, hemp-seed size, grayish-red nod- 

 ules on the mucous membrane are characteristic, which remain 

 for a long time, and only exceptionally change to small ulcers. 

 In horses dourine comes into consideration; in this however 

 there is also no vesicle formation, and it develops with less 

 acute symptoms and is later associated with nervous mani- 

 festations. 



Treatment. Mild cases recover without any treatment. 

 Keeping the genital organs clean and washing with mild disin- 

 fectants and astringents hasten the recovery. For this pur- 

 pose alum, sulphate of zinc (%%), boracic acid (3%), iron and 

 copper sulphate (1%), acetate of lead (1-2%), carbolic acid, 

 creolin, lysol, or chinosol in 2-3% solutions, may be used, with 

 which the affected parts should be washed two or three times a 

 day. In the presence of a severe vaginal catarrh, irrigations of 

 the vagina with the same solutions may be undertaken. If the 

 ulcerations are unclean, with deep penetrating destruction of 

 tissues, they may properly be cauterized with nitrate of silver, 

 or copper sulphate. J. & H. Streit recommend the blowing into 

 the vagina of a powder consisting of four parts of sulphate of
