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.
Microorganisms â bacteria, archaea, fungi, algae, viruses and protists â are often easy to overlook. For the most part (except fungal fruiting bodies seen as mushrooms) we canât see microbes. The effects of microbes we feel are usually associated with an illness.icroorganisms â bacteria, archaea, fungi, algae, viruses and protists â are often easy to overlook.
