Control and Eradication 493 



branes may lie undiscovered for a long time and act as a focus for 

 the spread of the disease to other mares. The vaginal discharges 

 are also dribbled about over the herbage, to more certainly dis- 

 seminate the infection. The mare comes in close contact with 

 pregnant companions and may readily transmit the infection 

 directly to them. 



4. Exposed pregnant mares should at once be thoroughly dis- 

 infected, and especially the anus, vulva, tail, buttocks and hind 

 legs. These parts should first be thoroughly scrubbed with soap 

 and hot water to which has been added carbolic acid or lysol. 

 After this thorough scrubbing, the parts should be daily disin- 

 fected with a warm 2 or 3% .solution of carbolic acid or lysol, 

 for six or eight days. 



5. Immediately after the occurrence of an abortion in a stable, 

 or at the commencement of control measures, the vaginae of all 

 exposed mares which have not aborted, and have not been iso- 

 lated, should be subjected to rigid disinfection by irrigating them 

 with a warm i to 2000 corrosive sublimate solution. Should no 

 subsequent abortions occur, the vaginal disinfection need not be 

 repeated. 



After each fresh abortion in a herd, the control measures out- 

 lined should at once be renewed, each separate abortion being 

 regarded as fresh exposure of all contiguous animals. 



6. Ample precautions should be taken against the spread of 

 the disease through the medium of secondary bearers. Blankets 

 which have been u.sed on mares which have recently aborted are 

 highly dangerous when used upon, or brought in contact with, 

 pregnant mares. Harness may bear the infection, as may curry- 

 combs, brushes and other stable uten.sils. 



Workmen who have handled an aborted fetus, or its afterbirth, 

 or who have cared for the aborted mare, may readily carry the 

 infection to pregnant mares. Due precautions are to be taken 

 against such accidents. The clothing of such persons should be 

 kept clean ; if necessary, it should be disinfected. The hands 

 especially become soiled with infection-laden substances and 

 readily carry the malady. The shoes also constitute dangerous 

 bearers of infection. The manure, or other filth from the staU 

 where a mare has aborted, clings tenaciou.sly to the shoes, and 

 upon these the infection may be carried from one stable to 

 another.
