Microorganisms on the skin are either resident flora or transient flora. Resident flora are permanent residents of the skin and within the body, where they survive and multiply without causing illness. Transient flora are:
Microorganisms on the skin are either resident flora or transient flora. Resident flora are permanent residents of the skin and within the body, where they survive and multiply without causing illness. Transient flora are:
Resident skin microorganisms are not virulent. However, they can cause serious disease depending on the number of microorganisms present, their virulence, or ability to enter and survive in a host, and the susceptibility of the host.

Study Notes
Chain of Infection
- A cyclical process with steps including infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and host.
Infectious Agent
- Microorganisms include bacteria, viruses, fungi, and protozoa
- Can be resident or transient flora.
- Resident organisms are permanent, and transient organisms are temporary.
- Present on skin and multiply without causing illness.
- Ability to cause disease depends on the number entering the host and virulence/ability to survive
- The potential for microorganism disease depends on ability to enter and survive in a host.
- Resident skin microorganisms are not virulent, but can cause infection when a patient is severely immunocompromised.
Table 28.1 - Infections and Common Causative Organisms
- Provides common causative organisms by infection site.
- Example: Bronchitis - S. pneumoniae, H. influenzae, respiratory viruses
- Example: Device-related - Coagulase-negative staphylococci, Corynebacterium sp.
- Example: Endocarditis - S. viridans, S. aureus, Enterococci
