Viruses are not considered living pathogens because they lack the cellular structure and metabolic processes necessary for independent life. They cannot reproduce or carry out metabolic functions on their own; instead, they must infect a host cell to replicate. This dependency on host cells for reproduction distinguishes them from living organisms.
A virus is a non-living pathogen that invades body cells to replicate and cause infection.

Cancer is not considered a pathogen because it is not caused by an infectious agent like bacteria or viruses. Instead, cancer is a disease that arises from the uncontrolled growth and division of abnormal cells within the body.
Pathogenicity is the ability of an organism to cause disease.
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.
# No; a parasite is a living organism that feeds off another living organism's body, known as the host. A tumor is a group of cells that mutate and then reproduce rapidly normally with harmful effects. # Yes, if the tumor is considered an organism.
A pathogen = a virus. An organism, macro or micro, is alive, but viruses cannot technically be considered 'living.' Thus, non-pathogenic means 'not a virus'.
Anything that causes disease is considered to be pathogenic. This includes viruses and bacteria. People who come in contact with certain of these organisms may become very ill.
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.
Tuberculosis, Elephantiasis, African trypanosomiasis (Sleeping Sickness)
Whether a pathogen is considered alive depends on its classification. Viruses, for example, are not considered alive because they cannot reproduce or carry out metabolic processes independently; they require a host cell to replicate. In contrast, bacteria and certain fungi are classified as living organisms because they can carry out metabolic functions and reproduce on their own. Thus, the definition of life plays a critical role in determining the status of different pathogens.
