Infection caused by bacteria, viruses or other microbes. This is the clinical states in which the presence of a microbe in a host is suspected or discovered. Infection is the presence of microorganisms causing damage to body tissues, usually in the presence of acute inflammation (pain, swelling, redness, heat and loss of function). For example Staphylococcus aureus on intact skin does not cause a problem; it is the normal flora for skin. However if you cut your skin, Staphylococcus aureus can cause infection in the cut.
Microorganisms can also cause damage in the absence of inflammation but it is unusual, e.g. in neutropaenic patients with angio-invasive fungal infections causing tissue infarction.
