    Bovine Spongiform Encephalopathy (mad cow disease)

  • BSE (Bovine Spongiform Encephalopathy)

    Sometimes called “Mad Cow Disease”, and TSE (Transmissible Spongiform Encephalopathy). A disease of cattle presumably caused by a virus or other unidentified entity that affects the brain and causes the cow to behave erratically. Prevalent in parts of Europe but not in the United States. BSE is a contaminant that is undesirable in bovine sera. It is not known whether the causative agent can be filtered out since the causative agent itself is not known. In humans, it is believed to cause Creutzfeldt-Jakob, a disease affecting the nervous system.

  • BSE/TSE (Bovine Spongiform Encephalopathy/Transmissible Spongiform Encephalopathy)

    Transmissible Spongiform Encephalopathies are a class of lethal diseases characterized by brain lesions. Examples of TSEs include scrapie in sheep and goats, BSE in cattle and Creutzfeldt-Jakob disease in humans. The appearance of a new variant of Creutzfeldt-Jakob disease has raised concerns regarding the risk of transmission of these diseases from medicines containing certain bovine-derived ingredients.
