Unicellular infectious agents are prokaryotes, eukaryotes, bacteria, and protoza.
Various infectious agents can cause upper respiratory infections, such as viruses (e.g., rhinovirus, influenza virus) and bacteria (e.g., Streptococcus pneumoniae, Haemophilus influenzae). The most common cause of URIs are viruses.
A prion is an infectious protein that can cause misfolding of normal proteins in the brain, leading to neurodegenerative diseases like Creutzfeldt-Jakob disease. Viroids are infectious agents made up of short, circular RNA molecules that can infect plants. A vector is an organism that can transmit a pathogen from one host to another, most commonly insects. Viruses are infectious agents that require a host cell to replicate and can cause a wide range of diseases in plants, animals, and humans.
Persistent chemical agents, such as certain nerve agents (e.g., VX) and some forms of blister agents (e.g., mustard gas), can remain active in the environment for extended periods, leading to casualties for more than 24 hours. These agents can contaminate surfaces and remain toxic, posing a risk to individuals who come into contact with or inhale them long after their initial release. Their long-lasting effects make them particularly dangerous in warfare and terrorist scenarios.
Antibodies, also known as immunoglobulins, are proteins produced by plasma cells in the immune system to target and neutralize infectious agents such as bacteria, viruses, and other pathogens. These antibodies bind to specific antigens on the surface of the pathogens, marking them for destruction by other immune cells.
It is not known if infectious agents also cause MALT lymphomas outside of the stomach.
Unicellular infectious agents are prokaryotes, eukaryotes, bacteria, and protoza.
Prions are the smallest known infectious agents.
Pathogens are infectious agents.
By coming in direct contact with people that have the disease, or if the nature of the illness is such that the infectious agent can survive outside the body by making contact with those infectious agents where they are left by the carriers of the disease.

In general, infectious arthritis is caused by the spread of a bacterial, viral, or fungal infection through the bloodstream to the joint. The disease agents may enter the joint directly from the outside as a result of an injury or a surgical procedure.
The CPT code 87798 is used for DNA or RNA detection of infectious agents. It is used for infectious agents that do not already have their own specific CPT code.
infectious diseases and types of chemicals
fungi and protozoa and bacteria
The term you are looking for is "fomite." Fomites are objects or materials that can carry and transmit infectious agents, such as viruses or bacteria, from one person to another.
No. You also have bacteria, fungi, etc.
