INFECTIOUS DISEASES. 567 
disease. Various medicinal agents have been recommended and are 
being exploited for the treatment, but to the present time no satis- 
factory evidence has been established as to their merits. Bacterial 
vaccines prepared from the specific organism have been given limited 
trials, but to date they can not be considered as entirely satisfactory, 
since it will require considerable experience with them before their 
usefulness can be definitely established. 
The prevention should consist largely in sanitary measures di- 
rected toward .the disinfection of premises and animals. (For a 
method for disinfection of premises see article under that heading.) 
The following procedure is advised for the disinfection of ani- 
mals: To prevent a stallion from carrying:the infection from a dis- 
eased mare to a healthy one the sheath and the penis should be dis- 
infected with a solution of 4 per cent of compound cresol: solu- 
tion, lysol, or trikresol, or a 1 per cent carbolic acid or 1 to 
1,000 potassium permanganate solution in warm water. For this 
purpose it is advisable to use a soft-rubber tube with a large funnel 
attached to one end, or an ordinary syringe and tube would serve the 
purpose. The tube should be inserted into the sheath, and the fore- 
skin held with the hand to prevent the immediate escape of the fluid. 
‘In addition to this the hair of the belly and inner side of the thighs 
should be sponged with an antiseptic. This disinfection should in- 
variably precede and follow every service. 
With regard to the mares, a -period of three months should elapse 
between abortion and a subsequent breeding, and especially if there 
is any evidence of a discharge the breeding of the animal should not 
be undertaken. The mare showing signs of abortion should be imme- 
diately isolated and the fetus and membranes should be burned. 
The fetus should never be dragged across a barnyard or stable, but 
should be removed by other means by which the contamination of 
the premises may be prevented. The stall in which the animal 
aborted should be’ thoroughly disinfected and the genital organs of 
the mare washed daily with a disinfectant. The antiseptic washing 
recommended for the treatment of the stallions prior to and after 
breeding should be also used for the irrigation of the uterus of mares 
which have aborted. This treatment should be continued daily until 
all evidence of discharge has ceased. The isolation of the animal 
should be carried out for at least one month after the evidence of a 
discharge has ceased. 
By carefully and persistently carrying out the sanitary measures 
it may be possible to control and finally eradicate the disease. 
NAVEL ILL OF COLTS. 
Navel ill of colts is also known as joint ill, omphalophlebitis, 
septic arthritis of sucklings, and pyosepticemia of the newly born.
