Study Notes
Microorganisms and Infections
- Microorganisms are found everywhere and can exist in almost every environment.
- They can be found on body surfaces such as skin, intestines, and other open areas (e.g., mouth, respiratory system).
- Microorganisms can also inhabit the upper respiratory tract, vagina, and urinary tract.
Infection Definition
- Infection is the growth of microorganisms in body tissue where they are not usually found.
- An infectious agent (microorganism) can be transmitted through direct or indirect contact, or as an airborne infection.
Types of Infectious Agents
- Bacteria
- Fungi (including yeast and mold)
- Viruses (e.g., Zika virus)
- Parasites (including protozoa)
Types of Infections
Local Infection
- Limited to a specific part of the body where microorganisms remain.
- Can lead to chronic infections, which may occur slowly over a long period and last months or years.
Note:
- Acute infections typically appear suddenly or last for a short period.
- Chronic infections may take months or years to develop and can last for an extended period.
