The affection to which the foregoing names have been given is a chronic, mild, and apparently contagious disease of cattle, characterized by an inflammatory condition of the mucous membrane of the vagina and the development of nodules upon its surface. This disease is very widely spread, but from an economic point of view it does not appear to have great significance. Williams, who investigated it, asserts that it is difficult to find a single herd in this country which is free of this disease. He considers it of great importance, claiming that granular vaginitis has a vital relation to abortion. This view, however, is not substantiated by other investigators, it being now generally accepted that the disease is only rarely responsible for abortion, and further, that it exerts no apparent ill effects on the health of the animal and that it has no effect on the milk yield. _Symptoms._--Natural infection may take place either by direct contact of animals or at the time of service. Most of the cows in the affected herd contract the disease, but the bulls are rarely or very mildly affected. The inflamed condition of the membranes of the vagina results in a catarrhal exudate, and this discharge, which soils the external genitals and the tail, and the uneasiness and sometimes the straining of the animal, are the first and most prominent symptoms observed. Upon examination, small, hard, grayish nodules can be seen and felt upon the inflamed membranes. This acute stage may last for three or four weeks, then it gradually subsides and assumes the chronic form, only to flare up again as the animal comes in heat. These nodules are sometimes found on the membranes of the uterus, and some investigators have argued from this fact that it was responsible for abortion and sterility. Others, however, deny this and point out that the bacillus of abortion can be demonstrated in nearly every case. The importance of the disease is therefore in dispute and the decision must be left to future investigation. _Treatment._--The exaggerated importance which has been attached to this disease resulted in the exploitation of the most varied kinds of remedies for its treatment. It is true that with a protracted and laborious treatment it is possible to effect cures in from one to three months, but with our present knowledge of this disorder it is advisable to limit the treatment to animals which show an acute inflammatory condition of the vagina and vulva with a discharge as a result of the granular affection. The treatment should be local and confined to the application of antiseptic washes in the form of irrigations. For this purpose a 0.5 per cent solution of the compound solution of cresol or of Lugol's solution has been found satisfactory. PARTURITION (CALVING). SYMPTOMS OF CALVING.
