Overview
Among the almost infinite varieties of microorganisms, relatively few cause disease in otherwise healthy individuals.[1] Infectious disease results from the interplay between those few pathogens and the defenses of the hosts they infect. The appearance and severity of disease resulting from any pathogen depends upon the ability of that pathogen to damage the host as well as the ability of the host to resist the pathogen. Infectious microorganisms, or microbes, are therefore classified as either primary pathogens or as opportunistic pathogens according to the status of host defenses.

Infectious disease are caused by pathogenic microorganisms. These disease can be categorized into 4 main categories:
- Bacterial infections
- Viral infecions
- Fungal infections
- Parasitic infections
Each one of these pathological infections then can be categorized based on different methods:
- Bacterial classification based on:
- Gram staining mathod
- Gram positive bacteria
- Gram negative bacteria
- Oxidase containing method
- Oxidase positive bacteria
- Oxidase negative bacteria
- Lactose fermenting method
- Lactose fermenting bacteria
- Non-lactose fermenting bacteria
- Coagulase containing method
- Coagulase positive bacteria
- Coagulase negative bacteria
- Gram staining mathod
- Viral classification:
- Genetic material
- DNA virus
- RNA virus
- Number of genetic copies in the virus
- Single stranded genome
- Double stranded genome
- Genetic material
RNA viruses themselves can be categorized based on their ability to use host cell polymerizes or need to bring their own polymerizes with themselves into 2 categories:
- Positive stranded viruses
- Negative stranded viruses
