Summary
a devastating disease endemic livestock in the California foothills countries causes pregnant heifers to lose their fetuses in the third trimester, killing about 5% to 10% annually calf beef "culture" of the -a state lost 45,000 to 0,000 animals. The veterinary pharmaceutical industry has largely ignored, focusing on the largest markets. And researchers have long struggled to find a cause or cure. But after years of sleuthing, they identified the pathogen in ticks, which belongs to a class of soil microbes best known for their swarming behavior that slides to cause the disease. And sewing together the funding and collaborations, scientists have developed a promising vaccine and are now testing in thousands of heifers.
