DISEASE FOUND IN SEVERAL MISSOURI COUNTIES
Last month, the disease was found in six Missouri, including Bates, Howell, Oregon, Platte, Shelby and Webster, after being detected in Howell County last summer. The eight other states that have reported theileria are Virginia, West Virginia, Tennessee, North Carolina, Pennsylvania, Kentucky, Kansas and New York. ...
