Disease |
|
To transit a pathogen that may induce development of an infectious disease in another person. |
Infection |
|
The act of introducing disease, germs, or infectious material into an area or substance. |
Contamination |
|
Organisms that cause or induce disease in a host. |
Pathogenic Organisms |
|
Organisms that due to its own virulence is able to produce disease. |
True Pathogens |
|
An organism that exists as part of a normal flora |
Opportunist Pathogens |
|
The presence of macroscopic organisms on or in a host-environmental space. |
Infestation |
|
The ability or the genetic capacity for an organism to cause disease |
Pathogenisity |
|
The complete expression or fulfillment of an organisms capacity to cause disease |
Virulence |
|
To abate an organism that causes an infection or disease |
Attenuation |
|
Organisms that cause disease outside the host. |
Exogenous infections- measles, Diphteria, Tuberculosis, Syphilis |
|
Organisms that cause disease within the host |
Endogenous infection- actinomycosis |
|
Rapid onset...short duration |
Acute Infection |
|
Slow onset...long duration |
Chronic infections |
|
Infections that are readily transmitted from one host to another. |
Communicable infections |
|
Disease that occurs at a constanly low frequency in a community and are present at low levels all of the time. |
Endemic |
|
A disease that affects a large number of people in a community in a short time will appear with a high level of intensity for a short time. |
Epidemic |
|
World wide epidemic where persons all over the world become infected with the same disease. |
Pandemic |
|
A few persons get the disease at regular intervals. |
Sporadic |
|
Disease or infection not transmitted from one host to another. |
Non Communicable disease-Tetanus |
|
The first infection that host aquires after a state of health |
Primary Infections |
|
The second infections that the host aquires after the state of health. |
Secondary infection |
|
Infections caused by 2+ organisms |
Mixed Infections |
|
Remains confined to an area of infection where pathogens were introduces. |
Local Infection |
|
Moves and spreads through the body of the host during the course of infection. |
General infection |
|
An infection that localizes in one area of the body and then moves to another sight. |
Focal Infection- tooth Abscess |
|
the presence of bacteria in blood |
Bacteremia |
|
a more severe condition where bacteria are in blood for a longer period of time and are growing and reproducing. |
Septicimia |
|
A toxin or poison in the blood usually produced by bacteria. |
Toxemia |
|
The last infection that a host will have and is cause of death. |
Terminal infection |
|
Certain types of poisons are produced by bacteria. |
Toxins |
|
A toxin produced by microorganisms and excreted into its surrounding mediums |
Exotoxins |
|
Toxins released from the bacterial cell only when the cells die. |
Endotoxins |
|
A thick covering of the cell wall of bacteria which reduces or prevents phagocytosis of the bacteria |
Capsules |
|
A thick walled spore within a baterium |
Endospores |
|
Organism causing a disease is directly transmitted from one host to another in a short period of time. |
Direct Transmissions |
|
Involves the generation of droplet spray of contaminated respiratory mucous into the atmosphere |
Droplet infection |
|
Transmission in utero from mother to unborn fetus |
Congenital |
|
Disease indirectly passed from one host to another. |
Indirect Transmission |
|
Examples of direct transmissions |
Physical contact |
|
Indirect transmission |

|
Entry transmission examples |
Skin mucous membranes, respiratory tract, digestive tract, genito urinary tract |
|
Exit Transmission examples |
Feces, urine, semen, vag secretions, sputum, saliva, blood, pus lesions, tears |
|
Cardinal signs of inflammation |
1. local redness of skin 2. Increased local temp 3. local swelling 5. Sensation of pain 6. Loss of function |
|
Can be recognized by the immune system and spur the immune system to produce antibodies, which react specifically against antigens that stimulate their formation. |
Antigens |
|
Proteins that are produces by the immune system in response to an antigenic stimulous |
Antibodies |

Natural immunity |
|
Acquired through vaccination or immunization |
Aquired Immunity |
|
active having the disease and recovering from it |
