| + | A fifth controversial type are Pirons, which are infectious proteins that are believed to be the cause of bovine spongiform encephalopathy (BSE) and the human variant Creutzfeldt–Jakob disease (vCJD).<br /> |

| + | All exist as either: |
| + | *Primary pathogens ('''obligate'''): presence always corresponds with disease |
| + | *Secondary ('''opportunistic'''): prerequisites must be fulfilled before disease occurs |
| + | |
| + | Microorganisms can enter the body by three routes: |
| + | *'''Contact''': typically seen in dermatological infections |
| + | *'''Aerosol''': typically respiratory infections |
| + | *'''Orofecal''':typically enteric infections |
