Micropara Lab Mod 10 (Bacteria and Disease)

Pathogenicity

Ability of an organism to produce disease. An organism that can produce disease in human is said to be pathogenic.

Virulence

Describes the degree of pathogenicity of an organism or the degree to which an organism can produce disease.

Carrier

Person harboring the organism without signs and symptoms of the disease.

Fomite

Biological substances that can carry organisms.

Vector

Insects that transmit infection

Vehicle

Inanimate objects which can carry microorganisms.

Septicemia

Multiplying bacteria in the bloodstream.

Fulminant Infection

Infection that always leads to death

Nosocomial Infection

Hospital-acquired infections

Local infection

Infection confined to a limited area.

Bacteremia

Presence of bacteria in the blood

Toxemia

Presence of toxin in the bloodstream.

Endemic

The disease is constantly present in a population at low levels.

Epidemic

A great number of people in a given locality develop an infectious disease in a short period of time.

Sporadic

A disease that occurs occasionally

Exotic

An infectious disease that normally do not occur in the region.

Reservoir

This serves as the continual source of disease-producing microorganisms.

Reservoir

It is the site where an infection agent normally resides and multiplies. It provides the organisms with conditions that enable them to survive and multiply and provide opportunity for transmission to a susceptible host.

Portal of exit

Route by which an infectious agent exits its host. It is usually the site where the infectious agent is commonly located or localized.

Vector transmission

Vectors are usually insects that can transmit an infectious agent.
