A pathogen is any disease causing organism. There are many species of bacteria. Some cause diseases and some don't. The ones that cause diseases are pathogens and the ones that don't cause diseases are not pathogens. Of course a particular species of bacterium might cause a disease in dogs, for example, but not in humans (and vice versa) so it would be considered a pathogen in dogs but not humans.
Diseases not caused by pathogens include genetic disorders, mutations in the cells, and other disorders not caused by viruses, bacteria, prions, micro organisms, etc. An example would be muscular dystrophy or even cancer, although many pathogens can increase the likely hood of cancer developing
Yes. Mosquitoes and other biting flies are some of the worst offenders, spreading the pathogens that cause diseases such as yellow fever, malaria, and sleeping sickness. Fleas are the primary carriers of bubonic plague.
no all diseases are caused by pathogens . for example some disesae are caused by deficiency of vitamins ,proteins
The term pathogen is derived from the Greek παθογένεια, "birth of pain." or "that which produces suffering" and that's basically what a pathogen is. It is an agent that causes pain and suffering to its host through disease or illness. Put more simply, a pathogen is anything that causes a disease. The agents that cause these diseases are infectious microbes (more commonly known to people as germs or bugs) such as bacteria, viruses, fungi and parasites. There are many different types of these agents and not all of them are infectious or harmful. In fact the majority of them are harmless and some even beneficial. Therefore it is important to remember, that pathogens refer specifically to those agents that can cause disease, illness or harm to its host. So yes, in answer to the question. pathogens are harmful bacteria (but not just bacteria) that cause disease.
Some diseases can cure other diseases.Some types of bacteria can cure OR cause diseases
