What are groups of the microorganisms?
protozoa fungi bacteria viruses prions
Are viruses the smallest pathogens?
No, prions are smaller still.
What are 2 non-living pathogens?
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.
Why don't viruses and prions qualify as organisms?
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.
What are some characteristics of members of residents microbiota?
Archaea,Bacteria,Prions and Viruses
Describe how can viruses and prions can alter cell function?
Viruses can alter cell function by entering host cells and using their machinery to replicate and produce more virus particles. Prions, on the other hand, are misfolded proteins that can induce normal proteins in the cell to also misfold and accumulate, disrupting normal cellular function. Both viruses and prions can cause damage to cells, leading to various diseases and health problems.
Do all scientists believe viruses are alive?
Certainly not. It is a hotly debated subject. Viruses (and prions for that matter) are not alive in a conventional sense.
Viruses are the smallest known infectious agents?
Prions are the smallest known infectious agents.
What are 5 classes of infectious agents?
Prions, Viruses, Bacteria, Fungi, and Animal Parasites.
What is infectious diseases caused by?
"germs" -- bacteria, viruses, parasites, fungi, and possibly prions
What incomplete viruses have been linked to diseases like scrapie and mad cow?
Prions.
Are prions prokaryotic?
No. Prions are neither prokaryotic nor eukaryotic. They are similar to viruses - nonliving. However, they are more "nonliving" than viruses in the respect that they are just protein sans nucleic acid or anything cell-like.
