Study Notes
Normal Flora
- Normal flora refers to the microorganisms that are present on the skin and mucous membranes of a healthy individual.
- They are usually harmless and can even be beneficial to the host.
Opportunistic Pathogens
- Opportunistic pathogens cause disease when the host's immune system is compromised or when the normal flora is disrupted.
- This can occur due to various factors such as old age, antibiotics, or underlying medical conditions.
Resident Normal Flora
- An example of resident normal flora is Staphylococcus epidermidis, which is a bacterium that is commonly found on the skin.
Transient Flora
- Transient flora inhabit the skin or mucous membrane for a short period of time, usually less than 24 hours.
- Transient flora are typically composed of microorganisms that are acquired from the environment, such as bacteria, viruses, and fungi.
