Prions are unique infectious agents composed solely of misfolded proteins, lacking nucleic acids, while viruses are made up of genetic material (DNA or RNA) encased in a protein coat and require a host cell to replicate. Bacteria are single-celled organisms with a cellular structure, capable of independent metabolism and reproduction. Unlike viruses and bacteria, prions propagate by inducing abnormal folding in normal proteins, leading to neurodegenerative diseases without any genetic material involved.

Bacteria are single-celled prokaryotic organisms that can reproduce independently and have cellular structures, including a cell wall and metabolic machinery. In contrast, viruses, viroids, and prions are acellular entities; viruses require a host cell to replicate, viroids consist of short RNA strands without a protein coat, and prions are misfolded proteins that induce misfolding in normal proteins. Additionally, bacteria can carry out metabolic processes and respond to stimuli, while viruses and prions do not exhibit metabolic activity.
Prions are not susceptible to antibacterial or antiviral drugs because they are not living organisms like bacteria or viruses. Prions are misfolded proteins that cause other proteins to misfold, leading to disease. They are resistant to most traditional forms of disinfection or drug treatment.
Careers associated with bacteria, viruses, and prions include microbiologists, who study microorganisms; virologists, specializing in viruses and their effects; and epidemiologists, who investigate disease patterns and outbreaks. Additionally, clinical laboratory technicians and pathologists analyze samples to diagnose infections. Research scientists in pharmaceutical companies also work on developing vaccines and treatments for infectious diseases. Finally, public health officials focus on managing and preventing the spread of these pathogens in communities.
Viruses and prions are examples of non-living pathogens. Viruses require host cells to replicate, while prions are misfolded proteins that can cause disease by inducing other proteins to misfold.

No. Mad Cow Disease is caused by prions, or misfolded proteins, not bacteria or viruses. Your immune system cannot nor have any means of fighting these prions because they are not recognized by the immune system as a threat.
No, prions are smaller still.

Both are missing some key characteristics of life - prions more so than viruses. The most prominent feature that is missing is the ability to reproduce without a host. Viruses can't reproduce without a host cell and prions can't propagate without a normal protein that is transformed into a prion.
