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

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.
