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.
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.
# 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.
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 = a virus. An organism, macro or micro, is alive, but viruses cannot technically be considered 'living.' Thus, non-pathogenic means 'not a virus'.
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)
Viruses are the only non-biological infectious agents; all otheres are forms of pathogen, which are bacteria.
