Detailed explanation-1: -The vast majority of microbes are harmless to us, and many play essential roles in plant, animal and human health. Others, however, are either obligate or facultative pathogens exerting a spectrum of deleterious effects on their hosts.
Detailed explanation-2: -Not all bacteria are harmful, and some bacteria that live in your body are helpful. For instance, Lactobacillus acidophilus-a harmless bacterium that resides in your intestines-helps you digest food, destroys some disease-causing organisms and provides nutrients.
Detailed explanation-3: -Pathogens include viruses, bacteria, fungi, and parasites that invade the body and can cause health issues. Anthrax, HIV, Epstein-Barr virus, and the Zika virus, among many others are examples of pathogens that cause serious diseases.
Detailed explanation-4: -Non-pathogenic bacteria are the ones that are incapable of causing any disease. They are also called non-infectious agents. They do not harm their host, instead can be beneficial to some.
