Study Notes
Types of Microorganisms
- Microorganisms include bacteria, viruses, fungi, and protozoa.
- Skin microorganisms are classified into resident and transient flora.
Resident Microorganisms
- Permanent residents of the skin that survive and multiply without causing harm.
- Difficult to remove through regular hand-washing unless significant friction is applied.
- Deep skin layers require antimicrobial products for effective removal.
- Staphylococcus aureus is a common resident microorganism of the skin.
Transient Microorganisms
- Temporary organisms that adhere to the skin after contact with people or objects.
- Example of contact leading to transient microorganisms: touching a bedpan or contaminated dressing.
- These organisms are loosely attached and can easily be transmitted if not properly removed.
- Escherichia coli (E. coli), typically found in the bowel, is an example of a transient bacterium affecting the skin.
Factors Influencing Disease Potential
- Sufficient quantity of microorganisms is necessary for disease.
- Virulence: The organism's ability to cause disease.
- Organism's capacity to enter and survive within the host.
- Susceptibility of the host plays a critical role in infection risk.
