Q

Infectious Agents Prion Details

A

Small protease resistant proteins

Derived from neurons, capable of converting others to abnormal proteins

Accumulation = neuronal dysfunction

Results in transmissible neurodegenerative diseases: Creutzfeldt-Jacob disease, Bovine spongiform encephalopathy, dementia

Mode of infection: Injection, transplantation of infected tissue, contaminated medical devices

Treatment challenges: No reproduction/metabolic functions

Q

Infectious Agents Viruses Details

A

Obligate intracellular pathogens

Protein coat +RNA/DNA

Incapable of replication outside of the host

Can cause cell lysis, latency, and oncogenesis
