Study Notes

Infection

Infection occurs when microorganisms grow in body tissue where they are not usually found.
Microorganisms in this context are called infectious agents.

Pathogenicity

Pathogenicity refers to the ability of microorganisms to produce disease.
A pathogen is a microorganism that causes disease.

Asepsis

Asepsis means freedom from disease-causing microorganisms.
There are two basic types of asepsis: medical asepsis and another type not specified in the text.

Medical Asepsis

Medical asepsis involves practices that confine specific microorganisms to specific areas.
These practices limit the number, growth, and transmission of microorganisms.
Medical asepsis has a significant protective role by preventing the colonization of pathogenic microorganisms.

Pathogenic Bacteria

Pathogenic bacteria have greater virulence and cause infections.
Chronic infections caused by pathogenic bacteria may occur slowly over a long period and last months or years.
