A virus is a non-living pathogen that invades body cells to replicate and cause infection.

A virus
A pathogen is a microorganism that causes disease such as bacterium and viruses. All viruses are pathogens, which means they all cause disease it causes disease But a pathogen is a living organism and a viru s is not so its really argumentive.
Pathogenicity is the ability of an organism to cause disease.
A pathogen (being something living from the goodness a body example: a tic living from a dog) 3 ways it can effect the host is: * disease of the host as the pathogen carried disease. * malnutrition of the host as the host can become weak due to the pathogen surviving from the hosts body. Example would be iron deficiency in the host, due to the pathogen using the hosts blood to live on * finally death of the host.

Viruses are the only non-biological infectious agents; all otheres are forms of pathogen, which are bacteria.
A virus is a pathogen that is made of nucleic acid surrounded by protein. Viruses can infect living organisms and hijack their cellular machinery to replicate and spread.
Microorganisms are living things that are so small that they can not be seen by the naked eye. When a microorganism causes a disease it is then called a pathogen. A host is a scientific term used to refer to whatever the pathogen is living in. So a host could be an animal, such as a human, or even a plant. An infection occurs once a pathogen enters a host. Disease occurs after infection once the pathogen disrupts homeostasis, or "the balance", in the host's normal functions. The study of this process is known as pathology, and the process of a disease being caused by a pathogen in a host is called pathogenesis.
Antibiotics are chemicals produced by living organisms that kill or inhibit the growth of other organisms, particularly bacteria.
