Microorganisms can be, according to their characteristics, divided into several groups: 1  bacteria, viruses, certain fungi and parasites. 2  pathogenic (capable of causing disease), non-pathogenic, and opportunistic (causing disease when they have an opportunity, like in people with low immune system).xamples of bacteria pathogenic for a human are: 1  Staphylococcus aureus, causing skin infections, pneumonia, infection of the heart valves, etc. 2  Streptococcus pyogenes, causing âstrep throatâ, cellulitis, etc. 3  Neisseria gonorrheae, causing gonorrhea.
A pathogen is an infectious agent that causes illness to the host. These are commonly attributed to be bacteria and viruses. They can also be simple organisms, such as Naegl â¦ eria fowleri [the uncommon brain eating ameoba].Most pathogens are infectious microbes, such as bacteria or viruses, which are capable of causing disease.Other parasites, such as fungi and protozoans, are also considered pathogens.Because not all microbes are harmful, pathogens refer specifically to those that can cause disease or other harm.   pathagens are bacterias.which cause people to get sick.hese are commonly attributed to be bacteria and viruses.
