Atypical H-type bovine spongiform encephalopathy in a cow born after the reinforced feed ban on meat-and-bone meal in Europe.

چکیده
The significance of atypical bovine spongiform encephalopathies (BSE) in cattle for controlling the BSE epidemic is poorly understood. Here we report a case of atypical H-type BSE in a cow born after the implementation of the reinforced feed ban in Europe. This supports an etiology of H-type BSE unrelated to that of classical BSE.

Bovine spongiform encephalopathy and spatial analysis of the feed industry.
In France, despite the ban of meat-and-bone meal (MBM) in cattle feed, bovine spongiform encephalopathy (BSE) was detected in hundreds of cattle born after the ban. To study the role of MBM, animal fat, and dicalcium phosphate on the risk for BSE after the feed ban, we conducted a spatial analysis of the feed industry. We used data from 629 BSE cases as well as data on use of each byproduct and...
متن کاملProtein nutrition for ruminants in European countries, in the light of animal feeding regulations linked to bovine spongiform encephalopathy.
The outbreak of bovine spongiform encephalopathy (BSE) and the discovery of the central role played by meat-and-bone meal (MBM) as the vehicle of infection resulted, from the late 1980s onwards, in the implementation of new regulations on the incorporation of animal proteins, and then of most fats of animal origin, into diets fed to ruminants and other farmed animals. The BSE-related feed ban, ...
متن کاملCase-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 کاملA spatio-temporal analysis of BSE cases born before and after the reinforced feed ban in France.
A spatio-temporal analysis was carried out to see how the risk distribution of bovine spongiform encephalopathy (BSE) in France changed depending on the period of birth. The data concerned the 539 BSE cases born in France after the ban (BAB) of meat and bone meal (MBM) in 1990 and detected between July 1, 2001 and December 31, 2003, when the surveillance of BSE was comprehensive. Seventy-two of...
متن کاملBSE, feed and cattle in Switzerland: is there a spatial relation?
Cross-contamination of cattle feed with meat and bone meal (MBM) allowed in feed for other species is regarded as the current hypothesis for the infection pathway of Bovine Spongiform Encephalopathy (BSE) cases occurring after the implementation of a ban on feeding MBM to cattle. This study was aimed at establishing a spatial relation between BSE cases in Switzerland and the findings of MBM in ...
