A specific diagnosis was arrived at in 1986. By June of 1990 there were 14,324 confirmed cases out of an estimated population of 10 million cattle in Great Britain (2, 22, 23, 104). Other cases have been reported in Ireland and Oman in 1989 and 1990, respectively (22, 23, 62, 52). BSE is an afebrile neurological disease that primarily affects mature cattle. Clinical signs include abnormally stilted gaits, high stepping, heightened sensory perception, itching, anorexia, excessive licking, and death. Abnormal motor nerve control coupled with aggressiveness have earned the disease the common name of Mad or Raging Cow Disease. Although all types of cattle are susceptible, most cases have been reported in the Holstein-Fresian breed. The first clinical signs of the disease (onset) has been observed in cattle at an age of 1 year 10 months to 15 years. From onset, the disease course varies from less than 2 weeks to 14 months usually resulting in death or humane destruction within 4 months (2, 9, 20, 22, 23, 31, 37, 69). The causative agent of BSE is not known, however, histopathological studies and clinical signs indicate a strong resemblance to that of scrapie. Brain extracts of suspect cattle have produced disease specific structures known as scrapie-associated fibrils (SAF). SAF are attributed to infectious type agents called prions. Prions are associated with a unique protein found in brain tissue called prion protein (PrP). Because scrapie has been transmissible via filtrates, the disease agent has been thought to be a virus. However, other characteristics of the disease do not readily fit traditional virus concepts (2, 6, 8, 9, 19, 31, 49, 54). In 1979 studies were conducted by the United States Department of Agriculture (USDA) to attempt experimental transmission of scrapie to cattle. Approximately 30% of the inoculated cattle developed progressive neurological signs of the disease. Upon initial histological examination scrapie could not be confirmed. However, a more recent examination of the same tissues, coupled with new information, have shown PrP structures to be present (2, 79). The incubation period for the disease has also been studied. Mice inoculated with BSE brain homogenates develop neurological signs of the disease 300 to 450 days later, therefore, indicating a prolonged incubation period before onset. In cattle the incubation period has been estimated to be from 2 to 8 years. Although the onset of BSE is observed in mature cattle the prolonged incubation period indicates that exposure can and does occur in calfhood. Calves have an estimated 30 times risk of exposure than adults (2, 31, 82). To date there is no evidence of animal to animal transmission of BSE. BSE is considered a "common source" epidemic, meaning that animals contract the disease from a common element in their environment. Evidence has ruled out sources of the disease such as semen, chemicals, autosomal inheritance, biologics and pharmaceuticals. The primary suspect disease source are diets fed to cattle containing ruminant based meat and bone protein. Scrapie or BSE contaminated carcasses which are rendered for ruminant diets may account for the presence of SAF in the brain homogenates of affected cattle. The feeding of animal protein specifically derived from ruminants was ceased in the United Kingdom as of July, 1988. Results of this control effort by the United Kingdom will not be assessable before 1992 (2, 9, 20, 23, 31, 91, 97). There have been no reported cases of BSE in the United States. As a preventative measure a prohibition of importation of ruminants from the United Kingdom was implemented in July of 1989. Scrapie and other forms of spongiform encephalopathy are present in the United States, hence, the intense interest in BSE. A transmissible form of spongiform encephalopathy found in ranched mink, transmissible mink encephalopathy (TME), in the United States has been primarily attributed to the feeding of scrapie infected sheep and goat carcasses. However, cattle carcasses (also part of the ranched mink diet) are now a suspect source of TME (2, 3, 4, 83). The USDA's Animal and Plant Health Inspection Service (APHIS) Veterinary Services program produces a Programs Alert on BSE (released in 1989) and a quarterly Foreign Animal Disease Report providing up-to-date information on diseases foreign to the United States including BSE. Copies of the Programs Alert and the Foreign Animal Disease Report may be requested from: USDA-APHIS, VS, 6505 Belcrest Drive, Room 741, Hyattsville, MD 20782.
