Abstract
Vibrio fetus, Smith and Taylor, is the principle etiological agent of ovine infectious abortion in the United States. During the 1952 lambing season, the lamb abortions were estimated at 50,000 in Colorado, 30,000 to 40,000 in Idaho, and from 10,000 to 15,000 each in Utah and Wyoming. A conservative estimate of premature lamb losses due to V. fetus infections in the western states for this year was 100,000. In infected flocks the incidence of mortality in aborting ewes may be as high as 10 percent. Since 1952 the incidence of vibrosis among sheep has remained high.
