The author had an oppotunity to observe three interesting cases of endometritis of cattle which were supposed to be caused by associate infection of organisms including Corynebacterium. In the autumn of 1943, a 4 year-old Guernsey cow of the Obihiro Zootechnical University herd, consisting of 14 cattle, aborted, discharging after that white-yellowish vaginal flora occasionally and failing to show normal oestrus. The brucellosis-tests were carried out with invariably negative results. The records of her breeding history is incomplete but it is known that she has aborted before. In the spring of 1945, a Jersey cow of 7 year, which calved normally a month before, and a Holstein-Friesian heifer of 3 year were observed to discharge similar vaginal flora and to show abnormal oestrus, being kept on either side of the above-mentioned Guernsey cow since the preceding winter. When the auther examined these three cattle in May of 1945, it was known that they had been affected by endometritis, their vaginal flora containing Corynebacterium like bacillus together with Staphylococci and Streptococci. Endometritis of cattle is not an unusual disease but it is rare that cattle which are placed next stanchion to each other are affected by endometritis at the same time. In this observation, therefore, it may be asserted below: 1. Corynebacterium can become the pathogenic germ which causes endometritis of cattle in co-operation with other organisms. It is considered that Corynebacterium is a facultative pathogenic bacillus and it will attack the cattle with its virulence when the cattle are in generally ill health, for instance, they are fed under so poor conditions that their nourishment is greatly deficient. It may be manifest that the cause of endometritis of the three cattle are contagious infection. 2. Uterine washings were carried out 3-7 times according to the symptoms of each individual and administration of sulfamine and injection of ovahormon were given simultaneously. As a result, the three cattle have recovered from their endometritis in 1-2 months after the beginning of the treatments. 3. The preferable intervals between uterine washings have been determines to be one week for bringing about best results. Physiological saline, methylene blue, or acriflavine solution has proved to be suitable for uterine washing. 4. Sometimes the cattle may show a bit of general disturbance such as loss of appetite, straining and decline in milk-production immediately after a uterine washing, but they recover usually in a short time.
