∙ 9y agoThe four broad types of pathogens are bacteria, viruses, fungi, and parasites. Each type of pathogen can cause various diseases and illnesses in humans and other organisms.
There are really 5 main groups; viruses, bacteria, fungi, protozoa (which includes the malaria parasite) and Helminthes (which includes parasites such as flatworms and roundworms). Moulds are classified as fungi.
Bacteria and virus
Influenza is a virus. It is a respiratory virus that infects the nose, throat, and sometimes the lungs. It is not caused by bacteria or fungi.

Virus
Earthworms, fungi, and most, but not all bacteria are detritivores. Bacteria can also be parasites, photosynthesizers, and chemosynthesizers.

Four different microorganisms are bacteria, viruses, fungi, and protozoa. Bacteria are single-celled prokaryotic organisms, viruses are infectious agents that require a host cell to replicate, fungi are eukaryotic organisms that include yeasts and molds, and protozoa are single-celled eukaryotic organisms that can be parasitic.
virus
A virus is typically the smallest of these three biological entities, as it is much smaller than bacteria and fungi. Viruses are even smaller than the smallest bacteria and fungi, and can only replicate inside the cells of a living host organism.
