Case-control study on feed risk factors for BSE cases born after the feed ban in France.
In France, after the ban on meat and bone meal (MBM) in cattle feeding in June 1990, cases of Bovine Spongiform Encephalopathy (BSE) have continued to be detected in bovines born after that ban (called BAB cases). A case-control study was therefore carried out to determine the way these cases were contaminated. A multivariate conditional model was built adjusting for the production type of the ...
متن کاملMad cows and computer models: the U.S. response to BSE.
The proportion of slaughtered cattle tested for BSE is much smaller in the U.S. than in Europe and Japan, leaving the U.S. heavily dependent on statistical models to estimate both the current prevalence and the spread of BSE. We examine the models relied on by USDA, finding that the prevalence model provides only a rough estimate, due to limited data availability. Reassuring forecasts from the ...
متن کاملTransgenic mouse brains for the evaluation and quality control of BSE tests.
Rapid BSE tests are widely used diagnostics in veterinary medicine and more than 11 million tests are applied worldwide. The evaluation of new rapid BSE tests and the quality assurance of approved BSE tests pose a challenge owing to the natural scarcity of BSE-infected bovine brainstems and regional variations in prion titer. Transgenic mice expressing bovine prion protein (Tg4092) offer an alt...
متن کاملClinical epidemiologic evaluation of BSE screening tests in Japan.
To address the public concerns provoked by the first incidence of bovine spongiform encephalopathy (BSE) in Japan, the BSE screening tests in Japan are evaluated in use of modeling analysis in evidence-based diagnosis. Under the assumptions based on epidemiological statistics such as the annual number of screened cattle with 1,227,385, the annual incidence of BSE infection with four, and the se...
