Yes, viruses are the smallest known pathogens that can cause disease in humans, as they are much smaller than bacteria and other microorganisms. Viruses rely on host cells to replicate and can infect a wide range of organisms, including humans, animals, plants, and even bacteria.
Yes. Diseases can be caused by: -Viruses -Bacteria -Protists - As well as Fungi. There are also diseases caused by the body. Such as autoimmune diseases and cancers.
Bacteria and viruses that cause illness are known as 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.
retroviruses
Yes they do
Yes, many viruses cause disease.
Viruses can affect animals, and some viruses can affect plants.
Viruses and bacteria that cause disease are known as pathogens. Some examples are herpes simplex virus and Mycobacterium tuberculosis.
Microorganisms that cause disease are known as pathogens, such as bacteria, viruses and fungi.
While most viruses co-exist harmlessly in their host and cause no signs or symptoms of disease, many of the viruses do cause fever.
Flu viruses cause disease, they cause influenza (flu). They are the infectious agents of the flu. The viruses are submicroscopic organisms that infect your body and that give you the influenza, the disease.
Pathogenic viruses cause illnesses and disease.
pathogen
No. Computer viruses are only called "viruses" by figurative analogy with biological viruses. And biological viruses (such as chickenpox, hepatitis, and the flu) are not the same as disease-causing bacteria (such as strep throat, tuberculosis, and lyme disease).
All things that can cause disease are microscopic: viruses, bacteria, and certain protists like amoebas.
