A case of prion disease acquired from contaminated beef

Spongiform encephalopathies are neurodegenerative diseases caused by misfolding of normal cellular prion proteins. A 2014 case of variant Creutzfeldt-Jacob prion disease in the United States was probably caused by eating beef from animals with bovine spongiform encephalopathy (BSE), or mad cow disease. Human spongiform encephalopathies are placed into three groups: infectious, familial or genetic, and sporadic, distinguished by how the disease …

Parasitic wasps (in the order Hymenoptera) inject their eggs into lepidopteran hosts, where the eggs go through their developmental stages. Along with the eggs, the wasps also deliver viruses carrying genes encoding proteins that inhibit caterpillar immune defenses. Some of these genes are permanently transferred to the lepidopteran host where they have assumed new defensive functions against other …
