Show Program Is Set For Dectection Of Bangs Disease Commissioner of Agriculture, Alden K. Barton, announced today to-day the inauguration of a program for the detection of Brucellosis (Bang's disease) in the milk produced pro-duced by the dairy cattle in the State of Utah. The test is officially offic-ially known as the milk ring test and was introduced into this country coun-try from Denmark in 1949. It is being employed in twenty-five states at the present time and is being introduced into the State of Utah by Dr. Grant E. Blake, veterinarian vet-erinarian for the U.S. Bureau of Animal Industry, stationed in Wisconsin. Wis-consin. Dr. Blake is formerly from Provo, Utah, and received his early education there. The project will be under the joint sponsorship of the State Department of Agriculture Agricul-ture and the U.S. Bureau of Animal An-imal Industry. Dr. John I. Curtis, who is the state veterinarian, will head the program for the State and Dr. F. H. Melvin, veterinarian in charge for the U.S. Bureau of Animal Industry. Dr. Wayne Binns head of the Veterinary Science Department De-partment of the Utah State Agricultural Agri-cultural College, who has recently returned from a year's study at Cornell University, will assist in technical details encountered with use of the test. The ring test is a test applied to the whole milk of cattle to detect he presence of antibodies for Brucellosis. Bru-cellosis. It is applied to the pooled milk of each herd to determine the exact Brucellosis status of each individual animals. The great value val-ue of the test lies in the fact that the milk of each herd of cattle in the state may be sampled once each six months, and only those herds showing a suspicious ring test reaction need be blood tested. The test is performed by, placing 1 cc: of pooled milk in the test tube which is then mixed with one drop of a stained antigen which is prepared pre-pared by staining a suspension of Brucella abortus organisms. When this suspension is mixed with milk which may have antibodies that are produced in the body of an animal an-imal which is infected with Brucellosis Bru-cellosis it will cause a clumping of the organisms contained in the antigen. an-tigen. As the cream rises these clumped organisms are carried to the top of the tube forming a purple pur-ple ring in the case of a positive test. If no antibories are present in the milk there is no clumping of the organisms, and a clear cream line is formed. Testing will get under way in Weber County about September 14 and spread to other parts of the state as time and personnel permit. |
