Infectious Diseases: What You . Infection: Results when a pathogen invades and begins growing within the host. Disease: Results only if and when normal tissue function is impaired. The body has defense mechanisms to prevent infection (i.e. burns, skin lesions). Most abundant molecule in cells making up 50% or more of their dry weight. Every protein has a unique structure, or shape. Allows it to perform a specific function. Enzymes are proteins that function as catalysts for many reactions in foods.

Bovine spongiform encephalopathy (BSE) is a progressive, fatal, infectious neurologic disease of cattle that resembles scrapie of sheep and goats. It was first diagnosed in the UK in 1986. Approximately 200,000 cases of BSE have been diagnosed in cattle, almost all of which were in the UK. In 1992, at the peak of the UK outbreak, 37,280 cases were reported in a single year..
