malady is such that it can be conveyed by an affected animal rub- 

 bing its hind-quarters or by whisking the tail against the external 

 parts of another animal, so that the tail of an affected animal should 

 also be looked after, washed, and disinfected. The treatment is the 

 same as noted in pars. 800 and 801. 



753. Coital Exanthema — a vesicular, pustular, and suppura- 

 tive affection of the generative organs, commonly known as the 

 ' disorder.' It is highly contagious and inoculative, and affects 

 both male and female, and varies very much in degree of severity. 

 Some cases are very slight, and resemble very much at the onset 

 genital erythema {par. 752), causing little or no constitutional 

 disturbance, while in others it assumes a more aggravated form. 

 When it makes its appearance in the male, numerous vesicles or 

 small blebs are noticed on the penis, which finally burst and form 

 little ulcers. In the female the external parts of the genital organs 

 are swollen and inflamed. The passage internally is studded with 

 small ulcers and spots of matter, causing an irritative discharge 

 from the parts. There is a great deal of itching, the tail is constantly 

 on the move, and also great inclination to urinate. In the mare it at 

 times assumes an epidemic form, showing all the symptoms of a 

 slight attack of pink-eye (par. 526). The animal drops off its food, is 

 very feverish, stiff, and dull, with swollen eyelids and limbs. These 

 symptoms are noticed in from seven to ten days after service. 

 Should the mare have a sucking foal following her, it as a rule 

 contracts the complaint shortly after the symptoms appear in the 

 mother. For further particulars and treatment, see par. 801. 



754. Obstructions in the Vagina. —False Membranes and 



Cords are often formed in the vagina by a doubling of the lining 

 membrane. They may run from side to side, or from roof to floor, 

 and before parturition can take place they have to be cut with a 

 knife, or broken down with the fingers. They usually cause some 

 pain, the animal getting up and lying down as if in colic ; but, as a 

 rule, no constitutional disturbance results. Long-necked tumours 

 are not infrequently found in the passage ; these have to be either 

 twisted or cut off. Abscesses are also sometimes formed in the
